摘　　要：阐述了储存条件下PE管材氧化诱导时间(OIT)性能指标的检测方法、制样方法与检测结果。通过对检测数据进行分析,并与新管材OIT经验值进行比对,研究PE管材在不同储存条件下,OIT随储存年限的变化趋势。提出OIT可作为表征PE管老化性能的重要指标,以及PE管材储存建议。The detection method,sample preparation method and detection results of the oxidation induction time(OIT)performance index of PE pipes under storage conditions are elaborated.By analyzing the detection data and comparing it with the OIT experience value of new pipes,the trend of OIT changes with storage years of PE pipes under different storage conditions is studied.It is proposed that OIT can be used as an important indicator to characterize the aging performance of PE pipes,and storage suggestions for PE pipes are given.
