The average value of three samples of the solution used in the execution standard is: %%.%.
Among them: medium pH: crack length percentage: crack sensitivity percentage: crack thickness percentage
． Test acceptance rules
The test should be accepted in batches. Each batch consists of steel plates with the same heat number, the same thickness, and the same heat treatment system. When the thickness is not greater than, take a set of samples, the sample size is the plate thickness ** When the thickness is greater than, take a set of samples from the thickness/, the sample size is **.
