Test Method: SATRA TM103
Resistance of elastics to repeated extension
March 2018
SCOPE
This method is intended to determine the resistance of elastic to repeated stretching to the limit of its useful extension both before and after an artificial ageing treatment. It is mainly applicable to elasticated fabrics but can be used to assess any extensible material.
PRINCIPLE
A test specimen of elastic material is reinforced by sewing a piece of polyurethane coated fabric to each end. The elastic is then repeatedly stretched to the limit of its useful extension, and any resulting damage is subjectively assessed at regular intervals. The test is stopped when either a set number of cycles has been reached or the damage to the test specimen has exceeded a predetermined level.
The test can also be carried out after the test specimens have been subjected to a period of storage at an elevated temperature.
