输送流体用热塑性塑料管 夏比冲击性能的测定 第 1 部分：通用试验方法

[中文适用范围]： 本文件规定了两种通用测试方法，方法 A 和方法 B，用于测定从用于输送流体的热塑性塑料管道上切割的无缺口和缺口试样的冲击性能。 — 方法 A：无缺口方法，适用于从用于输送流体的热塑性塑料管上切下的无缺口样本。 — 方法 B：缺口法，适用于从用于输送流体的热塑性塑料管上切下的样品，其中已加工出缺口。 采用方法A或方法B由相关产品标准确定。 本文件无意作为测定管道冲击强度的参考测试方法。 ISO 3127 涉及通过落体质量测定管道的冲击强度，是参考测试方法。 然而，当无法按照参考方法进行测量时，本文件可用于科学研究、材料测试或管道检查。 本文件可适用于管道的独立批次或连续生产。 [外文原描述]： This document specifies two general test methods, Method A and Method B, to be used for the determination of the impact properties of unnotched and notched specimens cut from thermoplastics pipes for the transport of fluids. — Method A: unnotched method, for unnotched specimens cut from thermoplastics pipes for the transport of fluids. — Method B: notched method, for specimens cut from thermoplastics pipes for the transport of fluids, into which a notch has been machined. The use of Method A or Method B is determined by the relevant product standards. This document is not intended as a reference test method for the determination of the impact strength of pipes. ISO 3127, relating to the determination of the impact strength of pipes by means of a falling mass, is the reference test method. However, this document can be used for scientific research, materials testing or the examination of pipe when it is not possible to take measurements in accordance with the reference method. This document can be applied to either isolated batches or continuous production of pipe.
