Three important acronyms

• RCMA is developing a Product Category Rule (PCR)

• A PCR is a roadmap for Life Cycle Assessment (LCA)

• The PCR template and results of an LCA are used to create an Environmental Product Declaration (EPD)


What is Life Cycle Assessment (LCA)?

• Methodology to assess the environmental impact of products, technologies, materials, and/or services

• Mass balance of inputs/outputs across a system

• Uses Life Cycle Thinking

• Tracks multiple environmental indicators

• Considers functional equivalence

• Governed by ISO 14040, 14044, and 14025

• Used for benchmarking and comparison

• Considers – Resource Acquisition, Manufacturing, Packaging and Transport, Use, and Disposal

• Requires a framework to classify expected performance and durability to be created

• Ensures transparency in comparisons



PCR Summary – Functional UnitFunctional UnitFunctional UnitFunctional Unit

The functional unit shall be 1m2 of covered and protected roofing membrane for a period of 20 years (the expected roof system lifespan extension provided by the coating).

• May require multiple coats or re-coats

• Includes the entire coating system needed to satisfy functional unit

PCR Summary – Systems ApproachSystems ApproachSystems ApproachSystems Approach

• Roof coatings often designed as a system comprised of multiple layers

• An individual layer may not satisfy the functional unit

Responsible

PartyActivity Milestone

Completed RCMA & NSF

Kick-off conference call with the Roof Coating Manufacturers Association to review development

schedule, identify potentially interested parties for outreach, and comments to initial draft PCR (as

applicable).

Completed Drafting TeamSeat PCR drafting team. NSF will provide teleconference arrangements for participants and a

demonstration of its Online Workspace and how it will be used to support PCR development.

Completed Drafting Team

Work with PCR drafting team to further develop the content of the draft PCR in accordance with ISO

14025 and ISO 21930. (Intermittently meet with full PCR committee to review the draft and solicit

feedback as needed)

CompletedCommittee

Transition PCR working draft to the full PCR Committee. Full PCR committee works to further develop the

technical content specific to the product.

June/July

(4 weeks)Review Panel NSF will submit the completed draft PCR for review by an independent PCR review panel.

July/August

(2 weeks)PCR Chair & NSF

The PCR Chair and NSF staff will manage and incorporate reviewer comments, as well as drafting

proposed language to resolve comments. The updated draft will be sent to the committee for review.

August

(2 weeks)Committee

Teleconference to review the independent PCR review panel’s comments and the PCR Chair & NSF’s

suggested revisions to resolve the comments.

September

(2 weeks)Committee Electronic ballot to approve the final PCR for publishing.

September

(2 weeks)NSF

Final editing of the PCR will be completed by NSF. The final PCR will be posted for public access.

Availability of the final PCR will be publicized through media releases, webinars, website postings, social

media, etc.

Maintenance

of the PCRNSF NSF will ensure the ongoing review and maintenance of the PCR at least once every five years.
