ISO 17697:2016规定了用于确定鞋面，衬里或内缝的接缝强度的两种测试方法，不考虑材料，以评估最终用途的适用性。 这些方法如下。 - 方法A:针穿孔。用于确定在垂直于该行的方向上将一排针穿过上部材料所需的力。 - 方法B:缝合接缝。用于确定鞋面和衬里材料中缝合缝的断裂强度。这种方法适用于从鞋子切割或制成模拟鞋类结构的接缝

ISO 17697:2016 specifies two test methods for determining the seam strength of uppers, lining or insocks, irrespective of the material, in order to assess the suitability for the end use. These methods are as follows. - Method A: Needle perforations. For determining the force required to pull a row of needles through an upper material, in a direction perpendicular to the row. - Method B: Stitched seams. For determining the breaking strength of stitched seams in shoe upper and lining materials. This method is applicable to seams cut from shoes or made up to simulate footwear constructions.
