4 Principle

Place the sample in the center of the adjustable pad and start the test machine to continuously and evenly withstand the axial load until the crack or regulation

The amount of deformation, record the corresponding load-deformation map or stress-strain diagram.

Note. Unless otherwise specified, the test is generally carried out at a temperature ranging from 10 ° C to 35 ° C. For temperature-critical tests, the test temperature is 23 °C ± 5 °C.
