What are SGS's zipper testing standards?

SGS is a leading global testing, verification, certification and technical services company offering testing and certification services for a wide range of products, including zipper products. They may have a range of standards and test methods to assess the quality and performance of zippers, depending on the type of product and industry.

Typically, zipper testing standards may include the following:

1. Appearance inspection:

   Appearance inspection is used to assess the quality of the zipper's appearance, including the inspection of the zipper head, chain teeth, slider and other parts. This may include checking the color, luster, surface defects, deformation, rusting, etc. of the zipper.

2. Functional performance test:

   Functional performance testing is used to evaluate the opening and closing operation, sliding performance and durability of the zipper. This includes tension testing, opening and closing cycle testing, sliding force testing, etc. to ensure that the zipper operates smoothly, is durable, and can withstand long periods of use.

3. Physical Performance Testing:

   Physical property testing is used to evaluate the strength, abrasion resistance, corrosion resistance, etc. of the zipper. This may include tensile strength testing, abrasion resistance testing, salt spray testing, etc. to ensure the performance and durability of the zipper under various environmental conditions.

4. Safety Performance Testing:

   Safety performance testing is used to evaluate the safety of zippers during use. This may include fire resistance, tear resistance, choking resistance, etc. of zippers to ensure the safety of zippers in various application scenarios.

Please note that specific zipper testing standards may vary depending on the type of product, industry and region. Therefore, when conducting zipper testing, it is recommended to refer to relevant industry standards, international standards (e.g. ISO standards) and standards and guidelines issued by authoritative organizations such as SGS to ensure the accuracy and reliability of the testing process and results.
