TestResources 3 point bend fixture and 4 point bend fixtures are available for Instron® E/M systems or any other test machine with TestResources adapters. 3 point bending fixtures enable flexural tests where strength or modulus are desired. 4 pont bending or flex test fixtures are also available. Three point bend fixtures can expand to 4 point flex test fixtures with added components. Industry standard flex testing methods include ASTM D790, ASTM D638, ISO 178, ASTM D7264, ASTM A360, ASTM C633, ASTM e855, ASTM D6109, ASTM D3043, ASTM C293 ASTM e1290, ASTM D6272, ASTM C1161, so care must be taken when selecting a product. Anvils adjust to different span specimens. The specimen is supported on two precision machined anvils of a desired radius. Force is applied centrally (3 pt bend test) or at defined distances either side of center (4 pt bend test). |
