Hardness reference materials in quality control: The boost for your process safety!
The daily verification, performed by the user, is described in the according hardness testing standards and significantly contributes to quality management processes.
In the daily verification process, all parameters of the hardness test system that build up to the hardness value, are examined by indentations on the hardness reference material.
This periodical inspection of the machine by means of hardness reference materials should be carried out immediately before the daily start of the test schedule.
If the device is used only once a week, the check should only be done on that day.
In three-shift operation, a check at the beginning of each shift is recommended.
An according documentation enhances the process safety, as value shifts due to damage or malfunction can be detected easily.
A comprehensive direct and indirect verification should be performed once a year as part of a calibration. The direct examination includes test force, measuring system, test cycle and indenter. Indirect testing using hardness reference material blocks, indicate the correct interaction of all the parameters that were checked in the direct verification of the testing machine.
In addition, the repeatability of results of the hardness testing machine can also be checked with the hardness test blocks.
