This document specifies a method for the determination of tear resistance based on the action of an active force applied to a notched test piece.
The test can be carried out on:
- test pieces that have been conditioned in a standard atmosphere; or
- test pieces that have undergone pre-treatment, e.g. water immersion.
The results obtained by this method cannot be compared with those obtained by methods involving constant rate of tear
