1. SCOPE
1.1 This test method measures the environmental stress crack resistance of polyethylene containers, which is the summation of the influence of container design, resin, blow-molding conditions, post treatment, or other factors that can affect this property. This procedure is particularly useful for determining the stress-crack resistance of a proposed commercial package containing an SCJ formula. However, this procedure is not designed to test the propensity for environmental stress-cracking in the neck of containers, such as when the neck is subjected to a controlled strain by inserting a plug.
