For the purposes of this document, the terms and definitions given in GB/T 3291.1 and GB/T 5707 apply.
4 Principle
Under specified conditions, a single fiber or a bundle of fibers of a certain mass is stretched to break on a constant rate of extension (CRE) tester, and the breaking force is obtained. The fiber breaking tenacity is calculated based on the breaking force and the linear density.
