This standard describes a method intended to determine the resistance of a slide fastener to repeated opening and closing. The method is applicable to all types of slide fastener with a teeth length greater than 80 mm. The free tapes at the open end of a test fastener are clamped together so that they are parallel. The fastener is held under tension along its length and across its width while it is repeatedly opened and closed. The test is stopped when the fastener has either failed or been subjected to a set number of cycles. The test standard is aimed at footwear manufacturers, manufacturers of zippers, trading companies and independent testing laboratories. The responsible committee for this standard is NA 062-10-11 AA "Schuhe" ("Footwear") at DIN Standards Committee Materials Testing (NMP).
