国内外测定氧化诱导时间试验方法标准综述

本文介绍了目前国内外采用差示扫描量热法(DSC)测定聚烯烃(PO)材料氧化诱导时间(OIT)主要使用的美国材料与试验协会标准(ASTM)、国际标准(ISO)以及我国国家标准(GB)等试验方法标准及其最新的进展情况,并结合本人日常进行热分析试验的工作经验提出了使用OIT方法需注意的问题,对今后我国转化ISO标准提出了建议。

This article introduced the cur- rent Chinese and overseas test method standards of determination for oxidation induction time by differential scanning calorimetry (DSC) and the advance in them,including ASTM, ISO and GB standards.Based on the experience of the author upon the thermal analysis,this article also pre- sented some issue in using OIT test method and some advice on transforming ISO standard to GB.
