欧洲和我国有关金属材料夏比摆锤冲击试验方法标准的对比

Comparing the China and European Standards on Metallic Materials Charpy Pendulum Impact Test Method

从标准的制定、试验原理、适用范围、试样及设备的要求、试验过程、试验结果的表示及评定等方面,对比EN 10045-1:1990《金属材料夏比摆锤冲击试验第1部分: 试验方法》和GB/T 229—2007《金属材料 夏比摆锤冲击试验方法》,说明2个标准在试样形状尺寸、试验程序及试验结果表示等方面存在的差异,由此导致试验结果评定会产生较大的不同。

The European standard EN10045-1 ： 1990 “Metallic Materials Charpy Pendulum Impact Test - part iirst： Test Method” and the Chinese national standard GB/T 229 - 2007 “Metallic Materials Charpy Pendulum Impact Test” are compared from the aspects of standards formulation, test principle, application scope, sample and equipment requirements, test process, indication and evaluation of test results, etc. The two standards have difference in the shape of sample size, test process and test result indication, which might result in significant different in the test result evaluation.
