The number of samples is 1 pair, and 1 sample is taken from each sole. The result is the lower value of the test results of the two shoes. 6.12.2 If the sample sole is made of hard material and is difficult to cut, use a cutter to cut a 50 mm × 15 mm piece of the outer soft material without cutting the hard material. Materials are then inspected according to GB/T 21396-2008. 7.Judgment Rules 7.1 The main items of labeling, physical and mechanical properties and sensory quality meet the requirements of this document, while the minor items of sensory quality do not meet the requirements of this document If there are no more than two items, the product is judged to be qualified. 7.2 If any of the following situations occurs, the product will be judged as unqualified. a) The marking does not comply with the requirements of this document; b) The physical and mechanical properties do not meet the requirements of this document; c) One or more of the main sensory quality items do not meet the requirements of this document; d) More than two of the minor sensory quality items do not comply with the requirements of this document. 8 Inspection rules and marking, packaging, transportation and storage Inspection rules, marking, packaging, transportation and storage shall be in accordance with QB/T 1187.
