Makers may use ramp and pendulum tests when they assign an A326.3 class
On 2 February 2022 the Tile Council announced that ANSI A326.3 had gained a product-use classification system and that a free digital copy of the standard was being offered. The release also describes how the association's lab can help a maker assign a class.
Tests named beside the friction method
The lab options in that release are the German ramp test in DIN 51130, the British pendulum tests in British Standard 7976 and ASTM E303, and the ANSI A326.3 dynamic coefficient of friction test. The release says those tests, possibly combined, can help the maker decide, together with internal quality checks, manufacturing parameters, and experience with similar surfaces.
The class is still the maker's statement
The release says products shall be classified into one or more categories and that the standard includes informative possible areas of use. It does not say a pendulum result replaces the maker's declaration.
