Application Summary AI generated

This standard specifies the procedures for verifying and calibrating Leeb hardness testers used on metallic materials. It is applied in manufacturing and quality control environments, such as metal fabrication and component inspection, to ensure the accuracy and reliability of portable hardness measurements. The standard is particularly relevant for field testing of large or installed metal parts where traditional benchtop hardness testers are impractical.
