现在遇到一个问题,向专业人士请教一下:
1.In case the total weight of the pieces of such a testing unit is less than 10 tons, one piece will be tested; in case of a large total weight two pieces are tested.
2.The impact value is to be determined as average from 3 tests at samples.
如果取拉伸试样,超出10吨可以取两根试样,应该没有异议,但是冲击试样感觉有点问题,一般一组冲击试样都是要求取3个试样,是取一组(3个)还是取两组(6个)呢?
