Introduction
Use the ASTM guide to take measurements on the relevant dimensions of your test specimen.
-
-
ASTM Standard D638 outlines the methods for tensile testing of plastics
-
Section 6 of the standard details the geometry of the samples being tested
-
measure each sample to ensure that they fall within the defined dimensions in standard D638
-
Take note of any deviations so that the dimensions can be adjusted in the Instron software
-
Features such as the grips and the machine's displacement rate are specific to testing plastics and therefore also outlined in standard D638
-
-
-
Samples should be flat and free of any damage to the gauge length, which could compromise the test.
-
Refer to the standard operating procedure for proper loading of each sample prior to tensile testing.
