Test force application
Test force application is a mechanical or electronic system that applies the static test load to the indenter. It ensures precise force introduction and prevents dynamic influences and measurement errors.
Physical-Chemical Mechanism of Action
Applying the test force introduces the static test load onto the indenter. This is done either by mechanical or electronic means to ensure that the force is transferred continuously and uniformly to the workpiece.
Metallurgical Relevance & Welding Risks
Inaccurate application of the test force can cause dynamic influences that lead to measurement errors. This can result in the actual hardness of the material not being measured correctly, leading to wrong conclusions and possible material selection errors in welding.
Workshop Practice & Action Instructions
To ensure precise application of the test force, follow these steps:
• Use a reliable mechanical or electronic system for force application.
• Make sure the system is correctly calibrated and checked regularly.
• Keep the test load constant and avoid rapid or irregular changes in force.
