标准摘要
[中文适用范围]： 本标准规定了由未增塑聚氯乙烯（PVC-U）、取向未增塑聚氯乙烯（PVC-O）、氯化聚氯乙烯（PVC-C）制成的管材拉伸性能的测定方法。 和高抗冲聚氯乙烯（PVC-HI、PVC-M 或 PVC-A），特别是以下性能： ——屈服应力和断裂应力； ——断裂伸长率。 注：ISO 6259-1 中给出了测定热塑性塑料管拉伸性能的一般试验方法。 本文件还在附录 A、B、C 和 D 中给出了相应的基本规范，仅供参考。 [外文原描述]： 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.
