Validating the specifications, value and safety axtm your raw materials, products and assets.
Formally confirming that your products and services meet all trusted external and internal standards. Intertek tests the shear response of polymeric matrix composites materials, by the ASTM D tensile testing method. ASTM D shear scope: Since the physical properties of many materials can vary depending on ambient temperature, it is sometimes appropriate to test materials at temperatures that simulate the intended end use environment.
ASTM D test procedure: Test specimens are placed in the grips of a universal tester at a specified grip separation and pulled until failure. If strain data is required such as Shear Strain or Shear Modulus of Elasticity along with Maximum Shear Stress, bonded strain gages are mounted to the specimen to measure strain response during the test.
Shear Response ASTM D
Elevated or reduced temperature test procedure: A thermal chamber is installed on the universal test machine. The chamber is designed to allow the test mounts from the base and crosshead of the Instron to pass through the top and bottom of the chamber. Standard test fixtures are installed inside the chamber, and testing is conducted inside the controlled thermal environment the same as it would be at ambient temperature.
The chamber has internal electric heaters for elevated temperatures and uses external carbon dioxide gas as a coolant for reduced temperatures.
The most common specimen for ASTM D has a constant rectangular cross section, 25 mm 1 in wide and mm 10 mm long. Optional tabs can be bonded to the ends of the specimen to prevent gripping damage. Intertek PTL can machine the specimens from larger samples and bond tabs if requested.
