Test Method for Determining Top Load Stress Crack Resistance

This method is used to assess the stress crack resistance of blow molded polyolefin bottles. It examines various factors such as material, blow molding conditions, bottle design, and contents that influence the resistance to stress cracks. The bottles are subjected to a constant top load at an elevated temperature. The amount of top load applied depends on the bottle’s size, weight, and design. The objective of this test is to compare the performance of one group of bottles to another group with the same design.
