<p>ISO 17697:2003 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.</p>
<p>These methods are:</p>
<p>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.</p>
<p>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.</p>
