GRI GM13 ASTM D3895 & D5885 Oxidative Induction Time of HDPE Geomembranes

This video describes ASTM D3895 “Standard Test Methods for Oxidative-Induction Time of Polyolefins by Differential Scanning Calorimetry,” and ASTM D5885 “Standard Test Method for Oxidative Induction Time of Polyolefin Geosynthetics by High-Pressure Differential Scanning Calorimetry,” as they apply to GRI GM13: Standard Specification for “Test Methods, Test Properties and Testing Frequency for High Density Polyethylene (HDPE) Smooth and Textured Geomembranes.” This specification was developed by the Geosynthetic Research Institute (GRI) under the auspices of the Geosynthetic Institute (GSI), with the cooperation of the member organizations for general use by the public. For further information, please consult our website: www.geosynthetic-institute.org GSI constitutes a diverse assembly of stakeholders who actively engage in the manufacturing, design and use of geosynthetics as engineering materials. GSI’s mission is to develop and transfer knowledge, assess and critique geosynthetics, and provide service to its member organizations. One of the major objectives of the institute is to develop and implement generic specifications of geosynthetics used in Civil Engineering applications all over the world.
