ASTM D3826 Standard Practice for Determining Degradation End Point in Degradable Polyethylene and Polypropylene Using a Tensile Test
ASTM D3826 用拉伸试验对聚乙烯和聚丙烯老化过程的最终老化点的测定的标准实施规程
适用范围
Scope:
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 of degree of degradation of a polyethylene/polypropylene film or sheet, but rather, to assess when in the course of its degradation under some condition, a brittle point is reached. If one wishes to monitor tensile elongation during the degradation process (such as when the tensile elongation is significantly greater than 5 %), Test Method D882 is recommended. This practice should not be considered the only way of determining a degradation-end point.
