Beskrivelse

1.1 This test method provides an indication of the environmental stress crack resistance of plastic tighthead drums as a summation of the effects of container design, resin, manufacturing conditions, field performance, and other factors.1.2 This test method may be used to evaluate a plastic drum's resistance to failure by cracking when in the presence of chemical and physical stresses.1.3 Two procedures are provided as follows:1.3.1 Procedure A—Internal pressure stress crack resistance method to nonyl phenoxypoly (ethyleneoxy) ethanol solution, a stress cracking reagent. The internal pressure is controlled at a constant elevated pressure and temperature.1.3.2 Procedure B—Top-load stress crack resistance method to nonyl phenoxypoly ethanol, a stress cracking reagent. The compressive top load is controlled at a constant weight while maintaining an elevated temperature.1.4 Although these procedures are not designed to test the ability of the closure or closure gasket material to retain
