METHOD OF TEST FOR ENVIRONMENTAL STRESS-CRACK RESISTANCE OF BLOW-MOULDED POLYETHYLENE CONTAINERS
This Malaysian Standard describes the test method to measure the environmental stress-crack resistance of containers, which is the summation of the influence of container design, resin, blow-moulding conditions, post treatment, or other factors that can affect this property. Three procedures are provided as follows:
1.1.1 Procedure A: Stress-crack resistance of containers commercial liquids
This procedure is particularly useful for determining the effect of container design on stresscrack
resistance or the stress-crack resistance of a proposed commercial package containing
a proprietary liquid product.
1.1.2 Procedure B: Stress-crack resistance of a specific container to polyoxyethylated nonylphenol, a stress-cracking agent
The conditions of test described in this procedure are designed for testing containers made from Type III polyethylene ASTM D 1248. Therefore, this procedure is recommended for containers made from Type III polyethylene only. This procedure is particularly
