Test and classify slip resistance of hard-surface resinous or terrazzo flooring under ANSI A326.3 DCOF

Steps

1. Confirm the current governing edition — ANSI A326.3 was revised in February 2022 (current as of 2026, verify at tcnatile.com) and introduced a five-category product-use classification (Interior, Dry Interior, Wet Interior, Wet Plus Exterior, Wet Oils/Greases) with minimum DCOF values roughly in the 0.42-0.55 range depending on category.
2. Match the flooring's tested DCOF value and product-use category to the actual installed environment — a wet processing area needs the appropriate wet-use classification, not just any published DCOF number.
3. Require wet-condition DCOF testing specifically, since A326.3 is a wet test method — dry-tested or unrelated slip claims don't satisfy the standard.
4. Obtain manufacturer test reports that reference the current A326.3 edition rather than accepting an unreferenced 'slip resistant' marketing claim.
5. Treat a passing DCOF number as one data point, not a full slip-risk guarantee — the standard's own literature notes it doesn't directly predict real-world slip risk under all contamination/footwear/wear conditions.
