ASTM D3826Standard Practice for Determining Degradation End Point in Degradable Polyethylene and Polypropylene Using a Tensile Test
ASTM D3826 is a tensile test method, which covers a degradation-end point, or a brittle point) for degradable polyethylene/polypropylene films and sheeting less than 1.0 mm thick.
Before conducting ASTM D3826, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
