The Workhorse: NSF Resinous Floor Coatings PCR
Most North American epoxy and polyurethane floor EPDs descend from the NSF “Resinous Floor Coatings” text published in 2018. It standardized primers, body coats, and topcoats so comparisons hold water (NSF, 2018). Dur-A-Flex, Sherwin-Williams, and Dudick used it for more than seventy declarations that still circulate in specs (EC3, 2025). Many timed under this PCR expired in 2024, therefore always confirm validity before bidding.
A Revised North American Rulebook Is Imminent
An ACA and NSF working group spent 2023 sharpening a successor aligned with the latest ISO 21930 and clearer service-life guidance (NSF, 2023). Release is expected before year-end 2025. Early drafts show mandatory biogenic carbon lines and optional digital modules that mesh with EPA’s C-MORE platform (EPA, 2024). If your renewals sit on the calendar, leave breathing space for this launch; filing under the old text on the eve of the new one cuts your runway short.

Going Global with EN 15804+A2
Stonhard bridged the gap by publishing 2024 EPDs under the International EPD System’s generic “Construction Products PCR 2019:14,” which follows EN 15804+A2 but omits the use phase, so like-for-like comparisons demand caution. Any construction-product EPD issued by an EU program operator has had to meet EN 15804+A2 since mid-2022, and the forthcoming Construction Products Regulation revision will bake that standard into digital product passports from starting this year (European Commission, 2023). In practice, EU projects now expect the EN 15804+A2 layout.
Program Operators Shape Perception
NSF and UL dominated the first wave of resinous floor EPDs a few years ago. Between 2023 and 2025, Smart EPD has published dozens more. CSA Group remains the favorite in Canada.
Choosing Your Best-Fit PCR
Start with where you make the product, not just where you sell it. If your epoxy is blended and packed in Ohio for U.S. hospitals, the forthcoming NSF revision covers that electricity mix, feedstocks, and haul distance. The same formula produced in Bavaria for a Frankfurt airport job rides a different grid and freight path, so it needs its own EN 15804 EPD.
