Method

Configuration Elongation

Sewing pattern Diamond ramp for 20 mm webbings Pattern 504

Measured following the ISA 41 elongation test (§9): the webbing is pulled to 1 kN (±0.1 kN) and held for one minute to let it settle, then a 200 mm gauge length is marked on the sample with two needles.

The force is increased to 5 kN and held for one minute, and the distance between the marks is read; the elongation is noted as a percentage of the gauge length. The same is repeated at 10 kN.
