3.1
strength at 300% elongation
strength of the specimen when stretched to 300% of the initial length
4 Principle
Under the specified conditions, the specimen is pulled off with a constant-rate-of-extension (CRE) strength tester to determine the breaking force, elongation at break and load at specified elongation.
