Standard Test Method for Environmental Stress Crack Resistance (ESCR) of Threaded Plastic Closures

Importancia y uso:

5.1 This test method compares closures for ESCR. Suitable variables are: closure materials, closure designs, processes, applied torque, and stress-crack agents.

5.2 Results can be used for estimating shelf life of closures in terms of ESCR. This requires that the user has calibrated failure time in this test to failure time in the field for actual packaging systems.
