标准范围
This part of ISO 16859 specifies methods for direct and indirect verification of test instruments usedfor determining Leeb hardness in accordance with ISO 16859-1, and also describes when these twotypes of verification are to be performed.The direct verification involves checking that individual instrument performance parameters fallwithin specified limits, whereas the indirect verification utilizes hardness measurements of referencetest blocks, calibrated in accordance with ISO 16859-3, to check the overall performance of theinstrument for testing in the direction of gravity. The indirect method can be used on its own for theperiodic performance checking in service.
