Steps
Do not cite ASTM C1028 (Static Coefficient of Friction of Ceramic Tile via horizontal dynamometer pull-meter) in a current spec — it was officially withdrawn by ASTM in 2014 with no direct ASTM-designated replacement issued in its place.
For current hard-surface flooring slip-resistance requirements, specify ANSI A326.3 (DCOF wet test, current 2022 edition) instead.
Flag any legacy spec or product data sheet still citing a C1028 static-coefficient value (e.g., an old flat 0.6-wet rule of thumb) for revision to a current A326.3 DCOF requirement.
For non-tile slip testing needs, confirm the specific applicable ASTM method and its current status directly on astm.org rather than assuming a single method 'replaced' C1028 across all surface types.
Communicate to clients/architects that 'meets ASTM C1028' is not a currently valid compliance claim, since ASTM no longer maintains that standard.
Known gotchas
C1028 was withdrawn in 2014 with no single ASTM-designated direct replacement — don't repeat the common but inaccurate claim that one specific standard universally 'replaced' it; different flooring categories have moved to different current methods (e.g., A326.3 for tile/hard flooring).
Old product literature or specs still citing C1028 values are a strong signal the document hasn't been updated — flag for revision to a currently valid slip-resistance standard rather than treating the citation as still valid.
