For the breaking force, it should be no break occurs under 2 times of lashing capacity. For the stretch limit, the strap must not break until reach the stretch limit.

Then the tensile strength will be assessed. A failure is when a permanent deformation occurred by visual test.

The third part is to assess the total length under lashing capacity. Result should be got satisfied elongation.

The fourth part is endurance test. The method is in 10000 load change with 1.25 lashing capacity, no sudden failure should occur. The product should functional after the test.
