This practice covers the determination of a degradationend point (a brittle point) for degradable polyethylene/ polypropylene films and sheeting less than 1.0 mm (0.04 in.) thick. This practice is not intended for determination of the rate or degree of degradation of a polyethylene/polypro
Tensile properties of plastics 1.0 mm (0.04 in.) or greater in thickness shall be determined in accordance with Test Method D638.
Use a static weighing-constant rate of grip separation test. This procedure employs a constant rate of separation of the grips holding the sample and a static load cell.
NOTE 1-This procedure is based on the use of grip separation as a measure of extension; however, the desirability of using extension indicators accurate to 61.0 % or better as specified in Test Method D638 is recognized, and a provision for the use of such instrumentation is incorporated in the procedure.
This procedure has been successful for determining the degradation end point of ethylene-carbon-mono
