When Is the Best Time to Use a zipper test?

 

The best time to use a zipper test is when the textile or fabric being tested contains a zipper or fastener that is intended to be used in the final product. This is because the presence of a zipper or fastener can affect the flammability characteristics of the textile or fabric, and may result in different flammability performance when the zipper or fastener is open versus when it is closed.

 

For example, if a textile is used to make a jacket with a zipper, the zipper test can be used to evaluate the flammability of the textile in both open and closed positions, which can help ensure that the jacket is safe and meets regulatory requirements for flammability.

 

It is important to note that zipper testing is just one type of flammability test method, and may not be appropriate for all types of textiles or fabrics. The appropriate test method will depend on the specific properties and intended use of the textile or fabric being tested. It is important to carefully select the appropriate test method based on the intended use of the product and to follow the testing procedures and requirements outlined in the standard in order to ensure accurate and reliable test results.
