ASTM D5397-99 Enviromental Stress-cracking Tester 

Model No.

 DW1441 ASTM D5397-99 Enviromental Stress-cracking Tester 

Application: 

DW1441 Environmental Stress Cracking Tester  is used to evaluate the stress crack resistance of polyolefin geomembranes by notched constant tensile load test. It is mainly applicable to the geomembranes used on the landfill site. Dumbbell shaped notched test specimens from a polyolefin sheet are subjected to a constant tensile load in the present of a surface-active agent and at an elevated temperature. The time to failure of test specimens is recorded and the results of a series of such tests conducted at different stress levels are presented by plotting stress level against failure time for each stress level on a log-log axis.
