Splashing test (4.2) 1 pair of shoe (the medium size of the range) per chemical yes Degradation test (4.3)
2 discs for outsole (one before and one after degradation)
2 discs for upper (one before and one after degradation) If possible Permeation test (4.4) 3 discs
per chemical yes All test pieces shall be conditioned in a standard atmosphere of (23 ± 2) °C and (50 ± 5) % relative humidity for a minimum of 24 h before testing, unless otherwise stated in the test method. The maximum time which shall elapse between removal from the conditioning atmosphere and the start of testing shall be not greater than 10 min, unless otherwise stated in the test method. For each of the required measurements performed in accordance with this standard, a corresponding estimate of the uncertainty of measurement should be evaluated. One of the following approaches should be used: — a statistical method, e.g. as given in
ISO 5725-2 [9]; — a mathematical method, e.g. as given in ISO/IEC Guide 98-3 [10]; — uncertainty and conformity assessment as given in ISO/IEC Guide 98-4 [11]; — JCGM 100:2008 [12] SIST EN 13832-1:2018

Key h height of the tested area 1 Test area Figure 1 — Tested area for the splashing test c) Store the footwear for at least 24 h in an environment at (23 ± 2) °C and (50 ± 5) %rh. The test shall performed between (20 and 25) °C. d) Fill the footwear with absorbent paper as a trace medium for liquid ingress. Ensure the paper is in contact with the seams of the footwear at the front, bellows and lacing in particular. e) Fasten the footwear. f) Prepare a minimum of 130 ml of the chosen test chemical. If several chemicals have to be chosen, it is necessary to use a new pair of footwear for each chemical. SIST EN 13832-1:2018
