This standard specifies the terminology, principle, test equipment, sample requirements and test procedures for ultrasonic contact Impedance Hardness testing of metal materials. It is applicable to hardness testing of metal materials and their coatings, platings and hardened layers. The ultrasonic contact Impedance method determines the Hardness of materials by measuring changes in vibration Frequency and is a dynamic test method for indirect measurement indentation. The standard provides uniform test methods and reporting requirements for the industry.
