AMC 25.793 and 25.810(c) Floor surfaces ED Decision 2020/024/R The slip-resistant properties of floor surface material should be tested wet with the type of slippery liquid expected during operation. In addition, dry testing should also be conducted to provide reference friction values. In all the test conditions, the dynamic coefficient of friction (DCOF) should be at least 0.45. The following standard methods, using rubber and leather test devices, are acceptable (within their limitations) to conduct the testing: — Military Specifications MIL-W-5044B (dated 24 February 1964) and MIL-W-5044C (dated 25 August 1970), titled ‘Walkway Compound, Nonslip and Walkway Matting, Nonslip’, — DIN 51131:2014-02, titled ‘Testing of floor coverings - Determination of the anti-slip property - Method for measurement of the sliding friction coefficient’, — ISO 8295:1995, titled ‘Plastics - Film and sheeting - Determination of coefficients of friction’, — EN 13893:2002, titled ‘Resilient, laminate and textile floor coverings - Measurement of dynamic coefficient of friction on dry floor surfaces’, ANSI/NFSI B101.3-2012, titled ‘Test Method for Measuring Wet DCOF of Common Hard-Surface Floor Materials’.
