标准摘要
[中文适用范围]： ISO 148 的本部分规定了根据 ISO 148-2 用于间接验证摆锤冲击试验机的合格试件的要求、准备和方法。 它规定了标称尺寸与 ISO 148-1 中规定的相同的缺口试件；然而，公差更加严格。 注 1：化学成分和/或热处理根据所需的能量水平而变化。 注 2：参考试件在参考摆锤冲击试验机上合格，ISO 148 本部分也对此进行了描述。 [外文原描述]： ISO 148-3:2016 specifies the requirements, preparation and methods for qualifying test pieces used for the indirect verification of pendulum impact testing machines in accordance with ISO 148‑2. It specifies notched test pieces with nominal dimensions identical to those specified in ISO 148‑1; however, the tolerances are more stringent. NOTE 1 The chemical composition or heat treatment, or both, are varied according to the energy level desired. NOTE 2 Reference test pieces are qualified on reference pendulum impact testing machines which are also described in this part of ISO 148.
