The residual indentation size of the indenter can be measured using optical measurement methods. Among the standardized optical hardness testing methods are the Brinell hardness test (ISO 6506, ASTM E10), the Knoop hardness test (ISO 4545, ASTM E92, ASTM E384), and the Vickers hardness test (ISO 6507, ASTM E92, ASTM E384). Brinell . Ultrasonic testing uses sound waves to non-destructively inspect a component for flaws. Introduction. Ultrasonic testing is a non-destructive testing technique because the workpieces or components to be tested are not damaged during the test. If there are no complaints after the test, the component can continue to be used. Hardness Testing Principles and Applications B-ASM-038.
