Scope

This standard specifies the test method for determining the stress crack resistance of polyethylene (PE) materials in environmental reagents. The test involves cutting notched specimens from injection-molded test pieces or products, immersing the specimens in environmental reagents maintained at a specified temperature, such as surfactant solutions, and applying a static tensile load to determine the failure time. This standard is applicable to evaluating polyethylene materials, as well as the effects of corrosive environments such as hazardous substances/chemicals on polyethylene extruded parts, such as pipe segments, polyethylene welded joints, and polyethylene blow-molded containers. Other thermoplastic materials, such as polypropylene (PP), can also be used as reference. Note: The stress/orientation of the products during processing may affect the results.
