The purpose of this standard is to describe a conventional method for measuring the shrinking and contracting forces of heatshrinkable films made from polyethylene, ethylene copolymers and their mixtures.
The method described in this standard can possibly be applied to other materials under proper operating conditions.
NOTE 1 This method also allows a shrinkage ratio to be assessed. However, the reference method for measuring the shrinkage ratio is ISO 11501, Plastics - Film and sheeting - Determination of dimensional change on heating.
