ISO 24267-2020 pdf download.Footwear- Determination of coefficient of friction for footwear and sole components一Test method. 5.5 High-hardness rubber material of at least 50 mm x 50 mm (thickness of 2 mm), for small- sized top piece testing (for testing according to 5). 5.6 Metallic plate made of e.g. aluminium, of at least 180 mm x 80 mm and 2,5 mm thick, for sheet material testing (for testing according to 86). 6 Sampling and conditioning 6.1 Sampling Two samples shall be tested, right foot and left foot whenever possible, with the exception of top pieces where 2 test pieces shall be tested and sheet material where 2 test pieces shall be tested per direction. 6.2 Conditioning The test items shall be conditioned prior to the test at 23 °C ± 2°C and 50 % ± 5 % HR (Relative Humidity) for a minimum of 24 h. If necessary, the sample may be removed from this standard atmosphere, provided that its temperature is maintained at 23 °C ± 2 °C, that testing starts within 30 mm after removal from this standard atmosphere and that the testing is carried out at 23 °C ± 2 °C. 7 Preparation of sample and floor All footwear test specimens shall be tested in the new condition so as to take account of the surface finish. Use method described in ISO 13287:2019. Clause 7, for preparation of samples and floor prior to testing. Worn footwear may be tested in the condition in which they are received. It is possible to evaluate the friction after simulating real wear by ageing the footwear. In this case, the ageing method shall be reported with CoF (Coefficient of Friction) results of aged sample. Prior to testing, condition test specimens according to 2. 8 Test method 8.1 Test modes and test conditions for footwear with tow heel seat height Test modes and conditions shall be those of ISO 13287:2019, excepting for children footwear, size below 34, in which a vertical force of 250 N instead of 400 N will be used Common contaminant conditions for daily footwear may be the following: — Detergent solution according to ISO 13287:20 19, 4.12.ISO 24267 pdf download.
