Scope

This document contains the Requirements for an Environmental Product Declaration (EPD) from the range of

Environmental Product Declarations published by UL Environment in coordination with the EN 15804 standard. The Requirements for the Background Project Report used to inform the EPD are contained in UL Environment’s Part A: Calculation Rules for the Life Cycle Assessment and Requirements on the Project Report. This Part B document, coupled with the Part A, conforms to the EN 15804 and ISO 21930 sustainability standards for EPD reporting. The document applies to: Joint compound as defined by ASTM C474 and C475 and applied in construction projects in accordance with GA-214. Joint compound is used in the finishing of interior gypsum panel products as defined per ASTM C1178, C1278, C1396, C1629, C1658, and C1766, CMU block, and any cementitious material. This PCR includes both ready-mixed and dry powders used in the finishing of interior surfaces in the North American market as follows, and gypsum plaster is specifically omitted from this PCR.

Ready mixed o Drying compound

Lightweight (<12lbs/gallon) Conventional (≥ 12lbs/gallon)

o Setting compound Lightweight (<12lbs/gallon) Conventional (≥ 12lbs/gallon)

Dry powders o Drying compound

Lightweight (< 12lbs/gallon) Conventional (≥ 12lbs/gallon)

o Setting compound Lightweight (< 12lbs/gallon) Conventional (≥ 12lbs/gallon)

The following code covers the scope of this Part B: Construction Specification Institute (CSI) Masterformat Gypsum

Board Assemblies: 092116 (Gypsum Board Assemblies), 092900 (Gypsum Board), and 079200 (Joint Sealants).

Note: Drywall joint compound products are used for joint treatment in Gypsum Board Assemblies as classified by CSI. Product types, components, or systems that are not included in the scope of this PCR but may be reported separately under additional reported information in Section 4 include fasteners, joint reinforcement tape, corner reinforcement and decorative trims. Example uses of joint compound include:

Compound for taping

Fill coats

Finish coats

Finishing corner reinforcement trims

Finishing fasteners

Skim coats

Other PCRs considered in the development of this PCR include:

Product Category Rules for North American Gypsum Boards. FPInnovations – Gypsum PCR-2013: v1PCR

Product Category Rules for preparing an environmental product declaration (EPD) for Product Group.

Technical - Chemical products for the building- and construction industry. NPCR 09. January 2012. The

Norwegian EPD Foundation.

The scope of this PCR differs from the two above in that it follows the EN 15804 standard, with modifications for the

NA market according to UL Environment’s Part A: Calculation Rules for the Life Cycle Assessment and

Requirements on the Project Report. This PCR follows the same modular reporting format, life cycle stages and

definitions and processes given in the Gypsum Board PCR, developed to be harmonized with the IBU PCR Part B:

Requirements on the EPD for Plasterboard, Oct 2012. However, unlike the Gypsum Board PCR, this PCR assumes



defaults of a 75 year product Reference Service Life (RSL) and 75 year building Estimated Service Life (ESL) to be

consistent with the IgCC (2015, Section 303.1), ASTM E2921 (2013, Section 6.1.1), and ASHRAE 189.1 (2011,

Section 9.5.1).

Given the difference in geographic scope with the Norwegian PCR, this PCR was developed to be specific to the NA

market.The EPD requirements include:

Requirements of the EN 15804 standard as a European core EPD for the purpose of consistency between

declarations in Europe and the United States.

Requirements of the ULE General Program Instructions v 2.0, April 2015 (available upon request)

The calculation rules for the Life Cycle Assessment and Requirements on the Background Report are

specified in a separate document as Part A of the Product Category Rules, available at

http://industries.ul.com/environment/transparency/product-category-rules-pcrs

EPD content, format, and use requirements

The chapters of the EPDs must be described in a compact form, as well as factually and technically correct.

Judgmental, comparative, or promotional texts are not permitted unless specifically requested in the PCR or if

necessary in the context of the EPD. Each document is carefully checked before publication.

Content of EPD. An EPD created using this PCR shall contain the required content specified in UL Environment’s

“Part A: Calculation Rules for the Life Cycle Assessment and Requirements on the Project Report” in addition to the

required content identified in this Part B document, which serves as a reporting template.

Extent of an EPD. An EPD may contain multiple data sets representative of a collection of products, as long as

each product is uniquely identified either explicitly in the EPD, by product category or by reference to a document

that lists included models. For example, the base model of a carpet available in a variety of colors may be listed by:

each individual model number, a model classification that includes all colors, a range of model numbers, or a

reference to a catalog of model numbers that include all color variations.

Verification. An EPD created using this PCR shall be independently verified by a Program Operator acting in

conformance with ISO 14025. The project report shall also be available for independent verification by a Program

Operator as required in “Part A: Calculation Rules for the Life Cycle Assessment and Requirements on the Project

Report,” Section 3.

Validity. An EPD created using this PCR is valid for a five (5) year period from the date of issue.

Comparability. EPDs must not contain statements of the superiority of one product over a competitor’s product that

performs the same functions, or of one manufacturer against another. EPDs must not contain directly or indirectly

such comparative assertions.

The following ISO statements indicate the EPD comparability limitations and intent to avoid any market distortions or

misinterpretation of EPDs based on this PCR. ISO 14025 requires this statement be included: “Environmental

declarations from different programs may not be comparable”.

A statement shall be included that indicates, “comparison of the environmental performance of joint compounds using

EPD information shall be based on the product’s use and impacts at the building level, and therefore EPDs may not

be used for comparability purposes when not considering the building energy use phase as instructed under this

PCR”.

This statement must be included: “Full conformance with the PCR for Joint Compound allows EPD comparability only

when all stages of joint compound life cycle have been considered. However, variations and deviations are possible”.

Example of variations: Different LCA software and background LCI datasets may lead to differenct results for

upstream or downstream of the life cycle stages declared.

The EPD owner shall transparently indicate any comparability limitations.

Product-group-specific LCA calculation rules from PCR part A

No product-group-specific LCA calculation rules existing.

3. LCA Calculation Rules

3.1. FUNCTIONAL UNIT

The functional unit for joint compound is defined as 100m2 of covered substrate considering an installation scenario

as defined by a GA-214 Level 4 finish with the quantity adjusted for the measured shrinkage (testing per ASTM C474)

for a service life of 75 years. Additional optional reporting of 1000ft2 may be included.

NOTE: Finishing an interior space to a GA-214 Level 4 finish includes treatment of joints, fasteners, flat joints (butts,

tapers), angle joints, corner reinforcement, and decorative trim. In practice, the volume required to cover 1000ft2

corresponds to a volume of 13 gallons of joint compound at 20% shrinkage. If deviations exist, they shall be

documented and justified.

NOTE: For purposes of defining a functional unit and reference unit, an ESL of a building in North America of 75

years shall be applied. The functional unit includes installed product and shall take into consideration shrinkage as

defined below and a 3% installation waste by default unless supporting documentation is provided.

Example: The functional unit for joint compound typically corresponds to a volume of 13 gallons/msf and is based on

a measured shrinkage value of 20% as determined per ASTM C474. For a joint compound with a different shrinkage

rates, the following equation would be used to determine the correct functional unit for that shrinkage value.

Needed volume for Functional Unit (gal/msf) = 10.1 gal/msf ÷ [(1 - shrinkage rate) x (1 - installation waste)]

Example 1 (20% shrinkage) = 10.1 ÷ [(1.00 - 0.20) x (1.00 - 0.03)] = 13.02 gal/msf conventional weight drying type JC

Example 2 (25% shrinkage) = 10.1 ÷ [(1.00 - 0.25) x (1.00 - 0.03)]= 13.88 gal/msf conventional weight drying type JC

Example 3 (15% shrinkage) = 10.1 ÷ [(1.00 - 0.15) x (1.00 - 0.03)]= 12.25 gal/msf lightweight drying type JC

Example 4 (0% shrinkage) = 10.1 ÷ [(1.00 - 0) x (1.00 - 0.03)]= 10.4 gal/msf 20 minute setting type JC



The functional unit, volume, density, the conversion factor to 1 kg, and the volume shrinkage rate shall be indicated

in the appropriate table as declared.

Per ASTM C474, shrinkage is defined as one (1) minus the ratio of the volume of the dry patty to that of the wet patty

expressed as a percentage.

3.2. SYSTEM BOUNDARY

The type of EPD shall be specified as cradle to grave. The modules considered in the Life Cycle Assessment as per

“System limits” outlined in section 6.5 of the PCR, Part A: “Calculation Rules for the Life Cycle Assessment and

Requirements on the Project Report” shall be described in brief. It should be apparent as to what processes are

considered in what modules per the module descriptions in section 6.5 of Part A.

3.3. PRODUCT SPECIFIC CALCULATIONS FOR USE PHASE (MODULES B1-B7)

There are no required product-specific calculations for the use phase (modules B1-B7). Impacts from the use phase

modules of joint compound are not anticipated and should be reported as zero unless otherwise justified.

3.4. ESTIMATES AND ASSUMPTIONS

Key assumptions and estimates for interpretation of the Life Cycle Assessment should be referred to here, provided

that they are not dealt with in other sections of 3 “LCA: Calculation rules”. Imperial units may optionally be included in

addition to the required SI units.

3.5. CUT-OFF CRITERIA

Cut-off criteria as specified per the PCR, Part A:

“Calculation Rules for the Life Cycle Assessment and Requirements on the Background Report,” Section 6.6 shall

be used and documented in the EPD and Background Project Report

3.6. BACKGROUND DATA

The sources for background data used must be provided and selection of data shall follow Part A, Section 7.3 and

collection of data shall follow Part A, Section 7.1. Primary life cycle data shall have priority.

If the variability in generic material or process data for any significant material or process leads to large variations in

the end result, the manufacturer shall seek to collect primary life cycle inventory data from their suppliers, if available.

3.7. DATA QUALITY

An evaluation shall be provided regarding data quality, including primary and background data age, geographic

representativeness, technological coverage, and completeness and shall follow the requirements outlined in Part A,

Section 7.4.

3.8. PERIOD UNDER REVIEW

The period under review and ensuing averages must be documented.



3.9. ALLOCATION

Part A, Section 7.5 shall be used as the basis for allocation decisions, and mass should be used as the primary basis

for co-product allocation in this Part B. Allocation methods deemed more appropriate than on the basis of mass may

be used but only when justified. The allocations of relevance for calculation (appropriation of impacts across various

products) must be indicated, at least:

• Allocation in the use of recycled and/or secondary raw materials

• Allocation of energy, auxiliary and operating materials used for individual products in a factory

whereby reference must be made to the modules in which the allocations are performed.

3.10. COMPARABILITY

A comparison or evaluation of EPD data is only possible if all data sets to be compared are 1) created according to

EN 15804 and 2) are considered in a whole building context or utilize identical defined use stage scenarios.

Comparisons are only allowable when EPDs report cradle-to-grave information using a functional unit. Refer to

section 5.3 of EN 15804 for further information

4. LCA: Scenarios and additional technical information

The following information is necessary for the declared modules. Irrelevant or non-applicable module rows may be

excluded in the EPD; additional information may also be listed if necessary

The following technical information is a basis for the declared modules or can be used for developing specific scenarios in the context of a building assessment if modules are not declared (MND).

REPLACEMENT (B4) / REFURBISHMENT (B5)

The number of replacements of product expected during the ESL of the building of 75 years shall be declared.

Required or expected maintenance are to be modeled according to manufacturer’s guidelines. Assumptions and key

parameters must be clearly stated and the manufacturer is to submit supporting documentation to justify the

assumptions made.

When reporting an RSL other than the default value of 75 years, the RSL is expected to be less than the ESL of a

building in North America. In this case, the number of replacements that will be necessary to fulfill the required

performance and functionality over the building ESL shall be identified.

Replacements should be rounded-up to the highest integer instead of a fraction over the course of the ESL of the

building; e.g., 1.6 rounded to 2. That is, if the RSL is greater than remaining life of the building, the aspects and

impact of a whole RSL must be used, not a fractional RSL corresponding to the remaining expected building life.

6. LCA: Interpretation

To facilitate comprehension of the Life Cycle Assessment, both the aggregate indicators of the Life Cycle Inventory

Analysis (LCIA) and the estimated impact outlined in Section 5 “LCIA results” must be interpreted in a dominance

analysis.

This interpretation must also include a description of the time frame and/or variance of the LCIA results if the EPD is

valid for several products. An illustration of the results with figures is recommended, e.g. for the dominance analysis,

the distribution of impacts across the modules, the CO2-balance, etc. as appropriate for a reader's understanding of

the environmental profile of the declared product.

7. Supporting Documentation

The project report elements required to support the content declared in an EPD created using this document are

specified in “Part A: Calculations for the Life Cycle Assessment and Requirements on the Project Report.” These

project report elements include general information (Part A: Section 4), study goal (Part A: Section 5), study scope

(Part A: Section 6), and the life cycle inventory analysis, impact assessment, and interpretation (Part A: Section 7, 8,

and 9). Additionally, the project report shall include additional required supporting documentation specified in this

Part B and according to Part A: Section 10.

If relevant to the scope of the declared product, or due to the product material composition, it is recommended to

provide sufficient supporting documentation in the EPD and Background Report. When providing documentation,

testing protocols and other relevant information shall be indicated. If supporting documentation is not provided, the

reasons shall be indicated in the EPD and Background Report.

As a general rule, all statements must be documented with measured data (presented by the corresponding test

certificates). In the case of non-verifiable substances, the limit of detection must be included in the declaration.

Interpreting statements such as “… free of …” or “… are entirely harmless …” are not permissible.

8. References

The literature referred to in the Environmental Product Declaration must be quoted in full from the following sources.

Standards and standards relating to evidence and/or technical features already fully quoted in the EPD do not need

to be listed here. Part B of the PCR document on which they are based must be referenced.
