The judgment of the impact test results 1. when the product standards are not required, every single sampling steel pipe impact test when a group of three specimen should be adopted , a group of three samples' average value should be not less than specified value ( smallest averages ) , allowing its specified value.In one specimen of the worth less than specified value but should not be lower than 70 per cent of the specified value2. if single sample steel group three sample results did not meet the above requirements , but specimen of below specified value are not more than two, and below specified value 70 per cent of the sample not more than one,the factory may adopt from the same sampling steel on a group of three samples in the second test samples, if at the same time satisfy the following conditions, the sampling steel to be qualified: a) six samples the average of not less than specified value ; b) below specified value of specimen is not more than two; c) less than 70% specified value Impact test results judgement
