This Malaysian Standard provides procedures for an indication of the environmental stress crack resistance of plastics injection moulded open head pails, covers, and components as a summation of the effects of container design, resin, manufacturing conditions, field performance, and other factors.
This Malaysian Standard also covers molded polyethylene, open head, self-supporting, nonreusable pails intended for the packaging and transportation of nonhazardous goods. Pails are to have volume capacities between 1 and 7 gal (3.8L to 26.5L).
Two procedures are provided as follows:
This Malaysian Standard may be used to evaluate a container's resistance to mechanical failure by cracking when in the presence of chemical and physical stresses.
a) Procedure A, Specified stress-crack resistance test method
This procedure is particularly useful for quality control since the conditions of the test are specified.
b) Procedure B, User selected stress-crack resistance test method
