Measuring mechanical characteristics

Measuring mechanical characteristics

The value of a zipper is mostly determined by its strength and lifetime. The requirements are based on Hungarian and international standards. In Concordia’s own laboratory the strength is controlled with tensile testing instrument, the lifetime tests are made with special testing machine.
