OurG793 plastics compression test fixture has been created for these applications and it offers a modular design that serves multiple applications including the ASTM D695. In fact it can be configured to serve a broad range of polymer matrix composite applications and international test methods involving plastics. In fact, the first ASTM standard specifically written for the compression testing of composite materials (viz., ASTM D 3410 1) was not issued until 1975. It standardized the so-called Celanese compression test method (Fig. 1) developed by the Celanese Corp. in the early 1970s 2. This method required the use of a tabbed specimen of precise . The remaining load introduction is obtained by shear-loading the specimen surfaces. The combined loading compression (CLC) test method, ASTM D6641 5, is one of the most commonly used compression test method for composites. The specimen-gripping surfaces of the test fixture are coated with tungsten carbide particles for shear loading.
ASTM D695 is a test method used to determine the compressive properties of un-reinforced and reinforced plastics. It is used alongside its tensile test standard equivalent, ASTM D638.Together, ASTM D695 and ASTM D638 assess the fundamental material properties of polymers that are found in every industry and even every household around the globe.
