Determine whether a water-resistive-barrier (WRB) coating product used under an EIFS cladding has been evaluated to the applicable ASTM test methods before approving it for a project submittal.

Steps

1. Confirm ASTM E2570/E2570M covers test methods for evaluating WRB coatings used under EIFS or EIFS-with-drainage assemblies; the current designation is E2570/E2570M-07(2025) -- reapproved in 2025 -- not the older (2019) reapproval cycle
2. Request the manufacturer's ASTM E2570 test report for the specific WRB coating rather than assuming compliance from marketing literature
3. Cross-reference the EIFS manufacturer's system approval letter, since EIFS is a proprietary tested assembly and third-party WRB coatings must be separately approved for use within that specific system
4. Note the full ASTM standard text is a paywalled purchase (store.astm.org); plan reviewers typically rely on the manufacturer's test report summary, not the raw standard text
5. Check ANSI/EIMA 99-A-2017, or its current superseding edition, for how it references E2570 requirements within the broader EIFS specification
6. Before citing a designation year in a submittal, re-confirm on store.astm.org that no further reapproval has postdated 2025
