ISO 17697 Footwear — Test Methods for Uppers, Lining and Insocks — Seam Strength
ISO 17697 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.
*** Before conducting ISO 17697 , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
