Earlier this year, a project was taken out to revise the impact testing requirements for PVC fittings in ASTM D2665, which included the addition of an exemption clause for bushings, increasers and closet flanges. The ballot passed and ASTM D2665-14 now contains the updated requirements. Accordingly, I am proposing to revise ASTM D2661 to include the same exemption clause that was recently added to ASTM D2665, not only to provide continuity between the standards for testing and certification purposes, but to remove a requirement that truly does not pertain to such fittings.
