| 摘 要： | 以无规共聚聚丙烯（PP?R）管材为研究对象，采用差示扫描量热仪（DSC）测试了PP?R管材的氧化诱导时间（OIT），并研究了测试部位、样品直径、样品厚度以及取样方式等测试条件对OIT测试结果的影响。结果表明，从垂直管壁方向取芯层直径为6 mm、厚度为650 μm的试样进行测试时，OIT测试结果相对可靠。

| 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. |
