标准范围

本文件规定了由未增塑聚氯乙烯（PVC-U）、定向未增塑聚氯乙烯（PVC-O）、氯化聚氯乙烯（PVC-C）和高抗冲聚氯乙烯（PVC-HI、PVC-M或PVC-a）制成的管道拉伸性能的测定方法，尤其是以下性能:-屈服应力和断裂应力；-断裂伸长率。注:ISO 6259-1给出了测定热塑性塑料管拉伸性能的一般试验方法。本文件还提供了附录A、B、C和D中相应的基本规范，仅供参考。

This document specifies a method for determining the tensile properties of pipes made of unplasticized poly(vinyl chloride) (PVC-U), oriented unplasticized poly(vinyl chloride) (PVC-O), chlorinated poly(vinyl chloride) (PVC-C) and high-impact poly(vinyl chloride) (PVC-HI, PVC-M or PVC-A), and in particular the following properties:— the stress at yield and stress at break;— the elongation at break.NOTE The general method of test for the determination of the tensile properties of thermoplastics pipes is given in ISO 6259？1.This document also gives, for information purposes only, the corresponding basic specifications in Annexes A, B, C and D.
