FOREWORD

This Indian Standard ( Second Revision ) was adopted by the Bureau of Indian Standards, after the draftfinalized by the Transport Packages and Packaging Codes Sectional Committee had been approved by theTransport Engineering Division Council.

This standard was first published in 1974. The second revision has been undertaken to bring it in line withISO 2873:2000 ‘Packaging — Complete, filled transport packages and unit loads — Low pressure test’ issuedby the International Organization for Standardization.

In this revision the following technical changes have been incorporated:

a) Concept of unit loads has been introduced;

b) The clause on test report has been revised; and

c) Table on atmospheric conditions has been added covering altitude from 4000 m to 20 000 m alongwitha new column on temperature.

The composition of the Committee responsible for formulation of this standard is given in Annex B.

PERFORMANCE TESTS FORCOMPLETE, FILLED TRANSPORT PACKAGES

PART 7 LOW PRESSURE TEST

(Second1 SCOPE

1.1 This standard specifies a method for subjectingcomplete, filled transport packages and unit loads toconditions of low air pressure similar to thoseencountered in aircraft.

1.2 This method, is applicable to complete, filledtransport packages and unit loads which are intendedto be transported in pressurized aircraft flying atany altitude and in unpressurized aircrafl flying at3500 m or less.

2 REFERENCES

2.1 The following Indian Standards contain provisionswhich through reference in this text, constituteprovisions of this standard. At the time of publication,the editions indicated were valid. All standards aresubject to revision, and parties to agreements basedon this standard are encouraged to investigate thepossibility of applying the most recent editions of thestandards indicated below:

7030:1988 Identification of parts for completefilled transport packages whentesting (firsl revision)

7031:2001 Method of conditioning for testingof complete, tilled transport packages( second revision)

3 TERMINOLOGY

3.1 For the purpose of this standard, the followingterm and definition shall apply.

3,1.1 Test Item

A complete filled transport package or unit load.

4 PRINCIPLE

4.1 The test item is placed in a pressure chamber,and the pressure in the chamber reduced to thatcorrespondifig to an altitude of 3500 m. This pressureis approximately equal to that in pressurized aircraftflying at any higher altitude. The pressure is then heldfor a predetermined period after which it is permittedto return to ambient pressure.

Revision )NOTE — While the pressure is held for thepredetermined period, the temperature may also bemaintained to that corresponding to the same altitude( see AnnexA ).

5 APPARATUS

5.1 Pressure Vessel

Pressure vessel, of sufficient size to accommodate thetest item, with pressure and temperature controls tomeet the requirements of the procedure given in 7.

6 TEST ITEM PREPARATION

6.1 Fill the test item with its intended contents andensure that the test item is closed normally, as if readyfor distribution.

NOTE— Simulated or substitute contents maybe usedon condition that the dimensions and physical propertiesof such contents are as close as possible to those of theintended contents, However, the closure should be thesame as for distribution.

7 CONDITIONING

The test item shall be chditioned in accordance withone of the conditions given in IS 7031.

8 PROCEDURE

8.1 Place the test item in the pressure vessel(see 5) and reduce the pressure at a rate not exceeding150 mbar/min, until it reaches 650 mbar( + 5 percent ). Maintain this pressure for thepredetermined period.

NOTE — lmbar = lhPa = 0.1 kPa.

8.2 Restore the pressure by allowing dry air atlaboratory temperature to enter at such a rate that theincrease in pressure does not exceed 150 mbar/min.

NOTE — If it is desired to study the effects of temperatureas well as pressure in pressurized aircratl, the atmospherein the vessel should be maintained at – 8 * 1“C duringthe predetermined period.

9 TEST REPORT

The test report shall include:

a) a reference to this standard;

b) the name and address of testing laboratoryand name and address of the customer;

the name, title and signature of personsaccepting test responsibility for the testreport;

a statement to the effect that the test resultsrelate only to the items tested;

a statement that the report shall not bereproduced, except in fill, without the writtenapproval of the testing laboratory;

the number of replicate test items tested;

a full description, including dimensions,structural and material specifications of thetest item and its fittings, cushioning, blocking,closure and reinforcing arrangements, grossmass of the test item and the mass of thecontents in kg;

k) the description of contents, if simulated forsubstituted contents were used, fill detailsshall be given;

m) the relative humidity, temperature and timeof conditioning; the temperature and relativehumidity of the test area at the time of test,whether these values comply with therequirements of IS 703 1;

n) the altitudes in which the test item was tested,using the method of identifi~ation given inIS 7030;

p) the temperature and pressure inside the ‘!pressure vessel, and the time for which they ~

were maintained;I

q) any deviation from the test method described 1

in this standard; and i

r) a record of the result, including anyobservations which assist in the correctinterpretation of the results.

ANNEX A

( Clause 4.1 )

ATMOSPHERIC CONDITIONS

A-1 The temperature in the holds of pressurized aircraftrarely falls below O°C. However the temperature ofpackages and unit loads on loading into the aircraftwill depend on the ambient temperature experiencedprior to loading as well as the subsequent ambienttemperature experienced in the hold prior to take off.These effects will persist for some time during flight.

A-2 The same ambient temperatures can also affectthe temperatures of packages and unit loads inunpressurized aircraft. When these aircraft fly above3500 m the pressure will drop to the values given inTable 1, and the temperature of the packages and unitloads will be affected to some extent by outside airtemperature at these altitudes depending on the lengthof the flight and the time/altitude profile of the flight.
