Elements C¢.a,- ~,-..~a:; SLrI~T~IT~,~ON: The need to clarify and simplify the language that now uses various but similar terms such as label, listing mark, classification mark, etc. Presently there is agreement that the current text contains problems with both confusion and omission. The attempt, in these proposals, has been to consistently use the word "label" when referring to a products ' marking for identification. There was some suggestion to use another word, in addition to "label", in instances where it would be impractical for the means of identification to contain pr inted information, such as a colored wire in glazing material. I have not included that suggestion because I believe that is of a sufficiently technical nature to warrant its own separate proposal. Maybe the definition of "label" can be broadened to include these means of identification and retain the simplification of the on word application. COMMITTEE ACTION: Accept.

AFFIRMATIVE: 26 NEGATIVE: Urban NOT RETURNED: Fridlyand, Hicks

EXPLANATION OF NEGATIVE: URBAN: (with regard to Section 1-4 only): Under the definition of

listed, replace the word "equipment" wherever it appears ($ places) with the word "products". The word "products" more closely represents the types of items covered By NFPA 80. COMMENT ON AFFIRMATIVE:

HUDNUT: Under Table 2-8 (a) Builders Hardware, Note 3 contains permissive language that I believe is no t in conformance with present NFPA policy. T h e first line should be revised to read: "some manufacturers are vermit ted to provide fire doors with....," I regard this as editorial. "

KOFFEL: I concur with the comment offered by Mr. Hudnut and the editorial change should be made.

"There are new developments in the area of glazing which show a resistance to the passage of heat beyond that discussed in AppendixJ -Radiant Heat Transfer. Historically, the fire resistance of glazing has been based on wired glass which is incapable of successfully meeting the fire exposure test criteria of NFPA 257, Standard for Fire Tests of Window Assemblies, and has been accepted as having a fire protection rating of 45-minutes. The newly developed glazing materials are capable of meeting the fire test criteria for as much as 3-hours and some have a low radiant heat transfer capability for as much as 1 and 1 1/2 hours." SUBSTANTIATION: To recognize new developments in the manufacture of glazing materials. The ceramic glass may meet fire test requirements for as much as 3-hours. New types of insulating glass will guard against the transmission of heat of sufficient magnitude to ignite wood for 30, 45, 60 and 90 minutes when

ositioned within 15 inches of the glass. OMMI'~EE ACTION: Reject.

(Log #48) 80- 8- (1-3.5 (New) and 15-2.3.2 (New)): Reject SUBMITYER: Rick Thornberry, The Code Consortium, Inc. RECOMMENDATION: 1. Add a new Section 1-3.5 to read as follows:

1-3.5 Signage. Signs installed on the surfaces of fire doors shall be in accordance with this section.

1-3.5.1 Fire doors which are normally closed or provided with self- closing devices shall be provided with an approved permafient sign which reads: "Fire Door - - Keep Closed." Such signs shall be installed on both sides of the fire door. Such signs shall be readily visible and shall contrast with the door surface finish. The letters on the sign shall contrast with the background finish of the sign. The letters shall no t be less than 1/2 in. high with a stroke width no t less than 1/16 in.

1-3.5.2 Information signs shall be permit ted to be installed on the surface of fire doors in accordance with this section.

1-3.5.3 The total of area of all at tached signs shall not exceed 5 percent of the area of the face of the fire door to which they are attached.

1-3.5.4 Signs shall be at tached to fire doors using an adhesive. Mechanical at tachments such as screws or nails shall no t be allowed.

1-3.5.5 Signs shall not be installed on glazing material in fire doors. Exception: Fire resistant glazing material. 1-3.5.6 Signs shall not be installed on the surface of fire doors so as

to impair or otherwise interfere with the proper operation of the fire door.

2. Also add a new Section 15-2.3.2 to read as follows and renumber the remaining sections accordingly.

15-2.3.2 When required by the authority having jurisdiction, an approved permanen t sign shall be installed on the face of the fire door to read: "Fire Door - - Do Not Block." The letters of the sign shall comply with Section 1-3.5.1. The installation of the sign shall comply with Section 1-3.5. SUBSTANTIATION: Presently NFPA 80 gives no guidance on the installation of signs on fire doors. There is a Section 1-3.4 which deals with plant-ons but they are not generally considered signs. This proposal provides guidance for the installation of signs that will minimize their impact on the fire performance of the fire doors to which they are attached. It also provides for mandatory signs to indicate when fire doors are required to be kept closed and when they are required to be prevented from being blocked. Signs indicating that fire doors should no t be blocked need only be installed at the discretion of the authority having jurisdiction in those cases where he continually finds doors blocked upon reinspection. C O M M I ~ ACTION: Reject. COMMITTEE STATEMENT: This proposal is beyond the scope of the standard. The requi rement for the siguage is not an installation standard but a maintenance standard. NUMBER OF C O M M I ~ E MEMBERS ELIGIBLE TO VOTE: 29 VOTE ON COMMITTEE ACTION:

AFFIRMATIVE: 26 NEGATIVE: Kinsock NOT RETURNED: Fridlyand, Hicks

EXPLANATION OF NEGATIVE: KINSOCI~ The necessity for indicating via mandatory siguage to

the building's occupants, that a fire doors closed position is vital to the safety of the occupants and the building. To assume that occupants know why a door has mandatory hardware and functions is fallacious and failing to inform them via siguage nullifies the reason for documen t 80's existence, which is the occupants safety. If the committee disagrees on the proposed location for siguage it is incumbent on them to designate an acceptable location.

(Log #24) 80- 9 - (1-4 Bottom Bar Sensing Edge/Reversing Edge (New)): Reject SUBMITTER: ClayWarix, Overhead Door Corp RECOMMENDATION: Add new paragraph to 1-4 definitions.

Bottom Bar Sensing Edge/Reversing Edge. A device mounted to the closing edge of electrically operated rolling steel fire doors that will stop a n d / o r reverse the closing door when it meets an obstruction. SUBSTANTIATION: The sensing edge which underwriter laboratories considers as s tandard on electrically operated doors should be included in the definitions paragraph. COMMITTEE ACTION: Reject.

(Log #2) 80- 10 - (1-4 Closed or Closed Position): Reject SUBMI'ITER:. Jeffrey E. Gould, Factory Mutual Research Corp. RECOMMENDATION: Add the following definition:

Closed or Closed Position: A position of the fire door assembly such that all latches are completely engaged within latch strikes or catches, and all edges of the door are fully engaged into or against locks, sills,jambs, stops, binders, guides or any other such devices used to secure the door and protect the opening f rom the passage of flame. Allowance is made for design clearances between items in the assembly. SUBSTANTIATION: Many sections of this Standard state to the effect, that doors will close when activated by some type of antomatic device; however, the term closed is not defined. For instance, f fa rolling steel door is activated and the bot tom bar stops 1 inch from the sill, is this sufficient to be te rmed closed? Also, if a swinging door comes to rest within the frame but the latch is not engaged, some may view the door as closed. A definition is needed to remove any ambiguity that may be associated with the term closed or closed PcOSition.

bot tom of one leaf and the top of the other protected with an astragal, bevel, or rabbit. Required hardware shall be located as shown in Figure B-26. SUBSTANTIATION: Quite often the subject of dutch doors arises especially in a health care setting. Unfortunately, except in Figure B-26, there is no reference to this type of door in the text of the code nor any reference in the definition section. I believe there should be some dialogue concerning dutch doors somewhere in the code.

EXPLANATION OF NEGATIVE: SIANO: I agree with the action but the substantiation is incorrect.

Glass lites can be usedin 4 hr doors if there are no thru openings and it is allowed by the authority having jurisdiction. THORNBERRY: I am opposed to this revision since it implies that

fire protection ratings greater than 3 hours are possible under the present codes and stan~lards. However, NFPA 259 is limited to a maximum 3 hour fire protection rating. Furthermore, all requirements contained in NFPA 80 are basedon the assumption that the highest fire protection rating for a fire door is 3 hours. Until such time as NFPA '252 is modified to allow testing of 4 hour fire doors or specific modifications to that test method are incorporated into NFPA 80 for the purpose of referencing the use of 4-hour fire doors, this proposed change is inappropriate.

, Exception : Where otherwise tested and approved. 2.8.4 Automatic Louvers. Only labeled fire door louvers shall be

used in fire doors. (See 1-3.2.) 2-8.5 Closing Devices. 2-8.5.1 Where there is an astragal or project ing latch bolt that

prevents the inactive door from closing and latching before the active door closes and latches, a coordinating device shall be used. A coordinating device shall no t be required where each door closes and latches independent ly of the other.

2-8.5.2 A closing device shall be installed on every fire door. Exception: Where pairs of doors are provided for mechanical

eqmpmen t rooms to permit movement of equipment, the dos ing device shall be permit ted to be omitted on the inactive leaf.

2-8.5.3 Attachment. All components of closing devices used shall be securely attached to doors and frames by steel screws or through- bolts.

2-8.5.4* Adjustment. All closing mechanisms shall be adjusted to overcome the resistance of the latch mechanism so that positive latchingis achieved on each door operation.

2-8.6 Door Holder/Release Devices. Holder / re lease devices shall be permitted in conjunction with doors illustrated in Figures B-20 tbrough B-28 and as shown in Figure B-51 when acceptable to the authority having jurisdiction.

2-8.7 Automatic Fire Detectors. 2.8.7.1 Detectors for the release of fire doors shall bepe rmi t t ed to

be part of an overall system, such as a fire alarm, water flow alarm, or carbon dioxide release system, which shall release the door.

2.8.7.$ Installation. Detectors and their components shall be installed in accordance with the manufacturer s instructions.

2-8.8 Operation of Doors. All swinging doors shall be closed and latched at the time of fire. For the purposes of this section the operation of doors is divided into three categories.

2-8.8.1 Self-Closing Doors. The door shall swing easily and freely and shall be equipped with a closing device to cause the door to close and latch each time it is opened. The closing mechanism shall no t have a hold-open feature.

2-8.8.2 Automauc Closing Doors. A door shall be permit ted to be made automatic closing by the installation of a closing device and a separate, labeled, fall-safe door holder / re lease device or a hold-open mechanism that shall be permit ted to be an integral part of the basic closing device or an integral closing device that permits free swinging of the door during normal operation and automatically closes the door during an alarm condition, provided the hold-open mechanisms are released by one or a combination of automatic fire detectors acceptable to the authority having jurisdiction.

2-8.8.3 Power Operated F'me Doors. Power operated fire doors shall be equipped with a releasing device that shall automatically disconnect the power operator at the time of fire, allowing a self- closing or automatic device to close the door irrespective of power failure or manual operation.

2-8.9 Application of Door Holder/Release Devices. 2-8.9.1" Door holder / re lease devices shall be installed in accor-

dance with the manufacturer 's instructions and only in conformance with the individual manufacturer 's published listings.

2-8.9.2 Location of smoke detectors used to control door bo lde r / release devices shall be as shown in Figure 13-51.

Exception: A detector shall no t be required on the exterior (outside) wall. 2-9 Astragals. 2-9.1 Doors swinging in pairs and having a fire protection rating of

more than 11/2 hours shall have an overlapping astragal. 2-9.2 Doors swinging in pairs, where located within a means of

egress, shall not be equipped with astragals that inhibit the free use of either leaf. The free use shall mean that the forces required to fully open any door manually in a means of egress shall not exceed 15 lbf (67 N) to release the latch, a 30 lbf (133 N) to set the door in motion, and a 15 lbf (67 N) to open the door to the minimum re.qu.ired width. These forces shall be applied at the latch stile to the mmLmum required width.

2-9.3 Pairs of doors that require astragals shall have at least one attached in place so as t op ro t ec t approximately 3 /4 in. (19.1 ram) or as may be otherwise indicated in the individual published listings. (See Figures B-21, B-23, and B-31; also see 2-8.2.4.) 2-10 Casketing. Gasketing on fire doors or frames shall be

furnished only in accordance with the published listings of the door, frame, or gasketing material manufacturer.

Excelption: Where acceptable' to the authority having jurisdiction, gasketang of noncombust ible or limited combustible material (see NFPA 220) shall be permit ted to be applied to the frame, provided closing and latching of the door is no t thereby inhibited.

2-11 Application, Installation, and Adjustment. 2-11.1 The installation of all components of a fire door assembly

shall be in accordance with the specific listing of each component . 2-11.2 All components shall be installed in accordance with the

manufacturer 's installation instructions and shall be adjusted to function as described in the listing.

2-11.3 All components of a fire door assembly shall be firmly attached to walls, doors, and frames in a manner acceptable to the authority having jurisdiction.

2-11.4 Mounting to masonry walls shall be by means of through- bolts except where steel shells are permitted elsewhere herein.

2-11.5 All mount ing screws, bolts, or shields shall be steel except wherepe rmi t t ed elsewhere herein.

2-11.6Attachment to doors with composite cores shall provide firm anchorage for anticipated use. SUBSTANTIATION: The need to deal with the specific recognition of components and providing for the ease of recognition of their labels after installation. This effort brought to light the need to rearrange the paragraph sequence of Chapter 2 which the Task Group generally agreed to be an improvement in addition to providing the opportunity to easily incorporate the solution to the problem of componen t recognition. In the workings of the Task Group, there seemed to develop some logic to dealing with this components question in Chapter 1 which would then allow it to be applicable to Chapters 2 through 13. Since the Task Group charge was specific and limited, I felt it better to keep it in Chapter 2 for now. It can be considered for broader application at a later time if the committee feels that is appropriate.

This reorganization does not include any of the actions taken on - n ( ~ ~ r e c e i v e d or acted upon.

"Change "4 (1.22)" max width to "4 ft -2 1/2 in. (1.28)" max width." SUBSTANTIATION: By increasing width 2 1/2 in, it is possible to have a clear opening between pairs of doors of 8 ft 0 in. in an 8 ft-0 in. corridor. In areas such as hospital corridors, damage to the door assemblies would be minimized by not having them protrude into the corridor where they are subject to abuse. By eliminating the need for constant adjustment and repair, the reliability of proper operation dur ing a fire emergency is increased and the public interest of fire and life safety is served. There is no discernible difference in the force-to-open requirement. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The standard has been developed on the maximum 4 ft door. An Increase in width would require reevaluation of testing and other requirements. See 1-2.

(Log #16) 80- 27 - (Table 2-8(a)): Reject SUBMITTER: Dennis V. O Neill, San Francisco, CA RECOMMENDATION: Delete the seventh line of Table 2-8(a). SU~TANTIATION: NFPA 80, Table 2-8(a) (Builders Hardware) lists two different min imum heights and thicknesses for spring hinges for the same size door and fire rating. It permits both a 4 in. and a 4-1/2 in. high spring hinge to be used on a 3 f t x 7 f t x 1-3/4 in. rated door. This is an obvious conflict, f f t he table permits a 4 in. high hinge, the requirement for a 4-1/2 in. hinge should be deleted.

The table purports to list m i m m u m hinge sizes. There can be only one minimum hinge size for specific door and rating.

If the table requires a 4-1/2 in. high hinge, with an exception permit ted for certain 4 in. hinges, the exception could be covered in the footnotes, al though this approach also dilutes the concept of a "minimum" hinge size. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The committee believes that for guidance a 4 1/2 in. hinge needs the greater thickness than does the 4 in. hinge.

hospitals and nursing homes. NOTE: Supporting material is available for review at NFPA

headquarters. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: If the height is to be increased above the 16 in. limit, testing is required.

NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 28 VOTE ON COMMITTEE ACTION:

AFFIRMATIVE: 25 NEGATIVE: Kinsock NOT RETURNED: Fridiyand, Hicks

EXPLANATION OF NEGATIVE: KINSOCK: The rejection of this proposal ignores "Real World"

conditions in hospitals, nursing homes and other occupancies. Without the protection of doors ' surfaces up to 42" above door bottoms, gouging of the surface to extents and depths is such as to invalidate the doors ' ability to withstand fire tests. The committee 's statement is self contradictory. It states any increase in height of kickplates should be tested, then adds "over 16" plates have been tested and failed." It leaves a "no-win" situation with no recommendation on solving the problem.

In cases where automatic closure is accomplished without the use of these devices and operates solely on the principal of gravity, the minimum closing speed may be reduced to no t less than 3 in. per second." SUBSTANTIATION: New products are available that utilize only gravity to close the curtain instead of spring related devices. Testing has shown that a speed as slow as 3 in. per second is adequate for these designs. In cases where a spring related device is used, a faster minimum speed is needed because of the counterbalancing effect of the spring. COMMITTEE ACTION: Reject.

The doors ' power supply shall be capable of being electrically supervised at a constantly a t t ended location and doors shall have an emergency power supply. Actuat ing devices shall be installed on both sides of doors. Doors shall be equ ipped with sensors capable of detect ing obstruct ions in their closing path and of signaling such detect ion at the doors ' location or at a constantly a t t ended location. Automat ic closing of the doors or trouble condit ions shall cause an audible alarm to be sounded at the door location. The alarm shall also be capable of be ing sounded at a constantly a t t ended location. Opera t ion of the activating device while the doors are open ing shall cause t hem to re turn to the closed position.

%8.2 Doors shall be easily recognized and be operable without a key, special knowledge, or effort. Doors shall be operable by a force of no t more t han 15 pounds applied to the actuat ing device in the direction of egress travel.

SUBSTANTIATION: The closing speed needs to be shown for consistency with paragraph 6-5.5. Also, as new products areavailable that utilize only gravity to close the curtain instead of spring related devices. Testing has shown that a speed as slow as 3 in. (75 ram) per second is adequate for these designs. In cases where a spring related device is used, a faster min imum speed is needed because of the

KOFFEL: I have changed myvote on this item to a negative vote for the same reasons indicated already by others, in particular Mr. Thornberry.

PACCHETTI: The transmission of heat through glass is critical because fire can and does spread through this form of heat transmission and since it is the charge of this committee, it should he included within the standard as a form of measurement. Further, without repeating it here, the first two paragraphs of AppendixJ clearly outline its need. RISPOLI: The information and references provided by this

appendix material are valuable to the end user in developing design criteria for the spedfication of glazing materials. THORNBERRY: I agree with the substantiation as far as it goes, but

this does not necessitate the proposal to delete the reference to

AppendixJ from this section of NFPA 80. This cross reference is appropriate because it provides useful information to the user of the standard when considering design options for the protection of window openings in fire resistive walls. That is the whole purpose of AppendixJ. It is not uncommon for NFPA standards to contain references to appendix items or appendices within the body of the code. In fact, this is done elsewhere in NFPA 80. For example, Section 1-3.1 references Appendix E. Section 1-3.4 references Appendix F. Section 1-3.5 references Appendix G. There are also many other references to the appendices of NFPA 80 throughout the standard, since the committee decided to retain Appendix J, it is evident that it contains useful information which should be referenced rather than ignored by not providing an appropriate cross reference within the body of the standard.

(Log #49) 80- 53 - (Appendix J): Reject SUBMITTER: Rick Thornberry, The Code Consortium, Inc. RECOMMENDATION: Delete the present text of AppendixJ and substitute the following:

AppendixJ Radiant heat Transfer Fire windows were originally designed for protecting openings in

exterior walls. In such applications, radiant heat transfer was no t a significant consideration since the main function of fire windows was to contain the flames within the building. However, where tire windows are used in interior partitions as borrowed lights and side lights, the user of this standard may need to consider radiant heat transfer during tire. Exiting through corridors past fire windows may be compromised and combustible materials on the unexposed side of fire windows could be ignited. The information which follows will assist the user in the evaluation of radiant heat transfer through fire windows.

Recent revisions to this standard have allowed very large areas of fire protection rated glazing materials to be used in interior parti-tions, only limited by the size of the test furnace. Also, recent technological advances in the glazing industry have compounded the problem of radiant heat transfer by making it possible to provide fire protection rated glazing materials of 60 and 90 minutes. Historically, fire windows including glass block have been limited to a 45 minute rating by the standard fire test, NFPA 257. This time limit was predicted on the failure of wired glass at approximately 1,600°F. Some European manufacturers have also developed fire resistant glazing assemblies which meet the requirements of a fire resistive rated wall assembly (currently up to 2 hours). These glazing materials, however, do not transmit excessive radiant heat since they are required to limit the temperature rise on the unexposed face to 250°F.

Since the present fire test standard, NFPA 257, does not require measuring and report ing temperature rise on the unexposed face of the glazing material or radiant heat transmission, glazing products tested to that standard have not been required to retard heat transfer. However, this data is required in many European fire test standards.4 As a result, European building codes place limitations on the use of giazing in fire resistive partitions inside buildings and require the use of insulating glazing in means of egress as well as where combustibles may be in "close proximity. Research by Margaret Law, Bsc., Ministry of Technology and Fire Offices Commit tee ,Joint Fire Research Organization,2,3 led to the development of such limitations in the British Building Code. This research provides a methodology for calculating safest distances from wired glass windows used to screen room fires from adjacent spaces.

Mrs. Law's research properly identifies two major concerns for the use of fire protection rated glazing in interior partitions. They are:

1. Impact on occupants exiting past the glazing. 2. Potential for non-piloted (auto) ignition of combustibles on the

unexposed side of the glazing. Both of these concerns should be considered by the user of this

standard when evaluating a specific tire protection rated glazing material for interior applicauon.

The exiting concern relates mostly to corridor applications where evacuating occupants may have to pass directly in f ront of the glazing which may be screening them from a tire. Calculation methods described in references 1 and 5 can be used to determine the radiant heat flux generated by a fire as well as the incident heat flux on a person located any distance beyond the unexposed face of the glazing. Safe distances for evacuees can then be de termined from Figures 2-4.39 and 2-4.40 of the SFPE Fire Protection Engineer- ing Handbook5 which provide data useful in estimating the time to threshold pain and skin burns caused by thermal radiation.

Traditional glazing materials have been prohibi ted from being used in exit stair enclosures because of the concern of radiant heat transfer. Not too long ago, the model building codes also incorporated requirements for limiting the temperature rise on the unexposed face of fire doors opening into exit stair enclosures to address the problem of heat t rans fe r (bo th conducted and re- radiated) which could adversely expose evacuating occupants who had to pass by the doors at each floor landing. Therefore, caution shou ldbe exercised when considering glazing materials with fire protection ratings of 60 minutes or more in such applications since they may transmit excessive radiant heat into the exit stair enclosure. However, glazing materials with fire resistance ratings would be suitable in such situations since they have been tested to limit heat transfer.

The concern for non-pUoted (auto) ignition of combustibles stored near a fire window requires an unders tanding of critical irradiation levels. Incident flux levels for auto-ignition of various combustible materials have been developed.2,6 Average values of 30-35 kW/m2 are normally used for ordinary (cellulosic) combustibles. Lower values have been identified for some synthetic materials.

The radiant intensity (heat flux) of the exposing fire will depend, among others, on the type of materials burning (rate of heat release) and the ventilation rate of the enclosing room. For well ventilated fires in light hazard occupancies such as offices, schools, institutions, and residences, a peak radiation intensity (output) of 85 kW/m2 has been used by Mrs. Law to represent a one hour fire exposure.3 Nelson 6 provides a me thod for de terming safe separation distances based on the radiant heat flux incident on a combustible material screened by wired glass (with a transmissivity of 0.5) from a fire (with an emissivity of 1.0) (blackbody). In general, a fully developed compar tment fire is viewed as a blackbody and therefore is assigned an emissivity of 1.0. To determine the radiation intensity, the following formula can be used:

I = eoT4 where I = Radiation intensity (kW/m2) e = Emissivity o = Stefan-Bol tzman constant

= 5.67xf10-11 k W / m 2 - ° K 4 T = Absolute temperature of the fire (°K)

For most situations the temperature of the compar tment fire is the only unknown variable. NFPA 72Eprovides someguidance for calculating room temperature based on different fire growth rates. Other methods base the temperature on the standard temperature - time curve used in NFPA 251 got ~ , _ _ on a fully developed compar tment fire assumed to have a temperature of 1,600°F (870°C or 1,140°K), the radiant heat flux would be approximately 105 kW/m~Z.

To determine the incident radiant heat flux on the unexposed side of the glazing, the following formula can be used:

li = FtI where li = Incident radiation intensity (kW/m2) F = Configuration factor for the glazed opening t Transmissivity of the glazing material I Radiation intensity of the fire ( kW/m2)

Transmisslvity of 1/4 in. wired glass has been repor ted in the range of 0.4 to 0.6. Many analyses have used 0.5 to account for the effect~ of re-radiation by the glazing product. Some manufacturers may be able to provide specific heat transfer information relative to their products.

The user should consider the significance of the source radiation, the transmissivity of the glazing material, the time of exposure, the separation distances, a n d the configuration of the glazed opening in relation to the target

Cont inuingwith the earlier example of a fire having a temperature of 1,600°F, the incident radiant heat flux ( l i ) for a window opening having a configuration factor of 0.35 in relation to a combustible target would be approximately 18.4 k W / m 2 . The reference documents provide detailed guidance for this analysis. SUBSTANTIATION: this proposed substitute AppendixJ Radiant Heat Transfer is a refined and editorially revised version of the original AppendixJ . It also contains additional technical information to supplement that originally provided in Append ixJ in order to assist the user of the standard to better unders tand radiant heat transfer through glazing materials.
