Abstract:

The oxidation induction time (OIT) of random copolymer polypropylene pipe was measured using a differential scanning calorimeter, and the effects of specimen site, diameter, thickness, and sampling method on the text results were studied. The results indicated that the OIT test results were relatively reliable when using the sample taken from the direction perpendicular to the pipe wall with a core layer diameter of 6 mm and a thickness of 650 μm.

Key words: random copolymer polypropylene pipe, test site, specimen diameter, specimen thickness
