ESCR (Environment Stress Cracking Resistance) Test

Polyethylene pipes are cracked under constant stress and in an area impregnated with detergents and oils. These cracks can cause defects in the tube if the cracks continue to grow.

To ensure the proper performance of polyethylene pipes in real applications, the performance of these products should be simulated in an active environment under specified temperatures along with stress, crack growth and cracks so that there is no problem with the investigations carried out in the application for polyethylene pipes and sheets. This is done by the ESCR test.

The most important and common methods of environmental resistance test are national standard 7607 and international standard ASTM D 1693. In this test, according to the related standard, the samples are bent and a controlled groove is created on each sample. These samples are placed in the agipal solvent impregnated environment with a known purity percentage and after the time mentioned in the relevant standard, the tests are examined for cracks.
