中文名称：灰口铸铁.梁的无切口冲击试验

英文名称：Grey cast iron — Beam unnotched impact test

发布日期：1975-11

标准范围

规定了确定冲击强度的要求。试验包括将一系列自由放置在支架之间的无缺口机加工圆柱形试样断裂，并测量试样断裂前后锤子动能之间的差异。附录A包括非标准试样，附录B包括冲击强度计算系数注释。

Specifies requirements for the determination of the impact strength. The test consists in breaking a series of unnotched machined cylindrical test pieces resting freely between supports, and measuring the difference between the kinetic energy of the hammer before and after fracture of the test piece. Annex A includes non-standard test pieces, annex B includes notes on coefficients for calculation of impact strength.
