《GB/T 18658-2002摆锤式冲击试验机检验用夏比V型缺口标准试样》由TC122（全国试验机标准化技术委员会）归口，主管部门为中国机械工业联合会。
本标准规定了按GB/T 3808对摆锤式冲击试验机进行间接检验所用标准试样的技术要求、制备和鉴定方法，同时也包括标准试样的检定证书。本标准描述的缺口试样以及标称尺寸与GB/T 229一致，但公差较严。试样预期的能量级不同，其化学成分和（或）热处理是不同的。鉴定标准试样用的摆锤式冲击试验机的要求也在本标准中予以描述。

Scope

This standard stipulates the technical requirements, preparation and identification methods of standard samples used for indirect inspection of pendulum impact testing machines according to GB/T 3808, and also includes the verification certificate of standard samples. The notched samples and nominal dimensions described in this standard are consistent with GB/T 229, but the tolerance is stricter. Specimens are expected to have different energy levels, different chemical compositions and/or heat treatments. The requirements for standard impact testing machines of the pendulum type for the qualification of standard specimens are also described in this standard.
