ASTM D covers the determination of tear strength or tear resistance of flexible plastic film and sheeting. The site of tear is initiated by a high stress. GeoTesting Express is a provider of Geosynthetic Testing Services – ASTM D,Standard Test Method for Initial Tear Resistance of Plastic Film and Sheeting.

The average thickness of the specimen is measured. Bluehill LE for Basic Testing. Non-repeatability of results — ASTM D requires the operator to exclude results that deviate markedly from the mean value.
Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. This test method aims to atsm force to initiate tear for plastic films that do no exhibit brittle failure or do not elongate greater than Experience has shown the test to have its best reliability for materials which do not have brittle failure or do not elongate greater than two hundred percent during testing.

Software for Series Systems. WaveMatrix 2 for Dynamic Testing. Glossary of Materials Testing Terms. Hence, tearing forces measured in newtons or pounds-force cannot be normalized over a wide range of specimen thickness without producing misleading data as to the actual tearing resistance of the material.
Certification Axtm confirming that your products and services meet all trusted external and internal standards. Instron self-tightening grips are primarily designed for the precision testing of films and other flexible materials exhibiting a large reduction in cross-section area under load. The specimen is die cut to the appropriate shape from a sheet. Email addresses must contain the symbol.
The specimen geometry of this test method produces a stress concentration in a small area of the specimen. The shape of the specimen is designed to create a tear when the specimen is pulled in tension.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The method is not applicable for film asfm sheeting material where brittle failures occur during testing or where maximum extension is greater than The specimen is then placed in the grips of the testing machine and pulled at a rate of 2 in. The maximum stress, usually found near the onset of tearing, is recorded as the tear resistance in newtons or pounds-force. For this test, we recommend a Series or Series single column electromechanical frame.
