PCR Created for Roof Coating Materials
ANN ARBOR, Mich. — Global public health organization NSF International, in cooperation with the Roof Coatings Manufacturers Association (RCMA), has created the first product category rule (PCR) in North America for roof coating materials. PCRs enable product environmental information to be more transparent and useful to the marketplace. Products covered in this PCR include fluid-applied and adherent coatings used for roof maintenance or roof repair, or as a component of a roof covering system or roof assembly.
Based on international environmental management guidelines (ISO 14025), a PCR defines how to conduct a life cycle assessment for a particular product group and what to include in the resulting report. A life cycle assessment measures inputs, outputs and environmental impacts of a product across its lifespan. The environmental product declaration (EPD) is the third-party-verified report that explains the data generated from a life cycle assessment.
The NSF International National Center for Sustainability Standards (NCSS) utilized an open consultative process to develop the PCR with participation from an expert panel of RCMA members, suppliers, regulatory agencies, environmental organizations and end users.
