41、heck compliance with the requirements specified in ISO 20345, ISO 20347 and any specific job-related footwear standards (e.g. ISO 17249, Safety footwear with resistance to chain saw cutting), together with the minimum number of test pieces taken from each sample, shall be in accordance with Table 1.
42、Wherever possible and necessary to ensure the essential safety requirements, test pieces shall be taken from the whole footwear. This paragraph is applicable to all of Table 1.NOTE 1 If it is not possible to obtain a large enough test piece from the footwear, then a sample of the material from which
43、 the component has been manufactured may be used instead. This should be noted in the test report.NOTE 2 Footwear sizes are defined in Annex C.Where samples are required from each of three sizes, these shall comprise the smallest, middle and largest size of the footwear under test indicated as (SML)
44、 in Table 1.4.2 ConditioningAll test pieces shall be conditioned in a standard atmosphere of (23 2) C and (50 5) % RH for a minimum of 48 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
45、 testing shall not be greater than 10 min, unless otherwise stated in the test method.4.3 Prerequisites on the testing procedureWhen several test pieces are tested, at least the worst results per size shall to be reported.Footwear shall be tested as it is intended to be used, unless otherwise specif
46、ied in the test method. For instance, if there is a removable insock, it shall be left in place to perform the tests.The uncertainty of measurement for each test method described in this International Standard may be assessed. One of the two following approaches should be used: a statistical method,
47、 e.g. that given in ISO 5725-2; a mathematical method, e.g. that given in ENV 13005.6DIN EN ISO 20344:2013-02 EN ISO 20344:2011 (E) Table 1 Minimum number of samples and test piecesProperty under test(B = basic requirement, A = additional requirement)Test only on the final footwearSubclause referenc
