Measuring the light emitted during this process enables simultaneous quantitative analysis of all required chemical elements in less than 30 seconds. It is thus possible to detect all metals, semimetals as well as a number of non-metals like, for instance, carbon, phosphorous, sulphur, oxygen or nitrogen. With that, spark spectrometry constitutes an outstanding quality control process for the metal producing and processing industry.

Ultrasonic Testing (UT) inspection is a commonly-used non-destructive testing (NDT) technique that measures the propagation of mechanical vibrations (ultrasonic waves) through the material to examine properties, measure thickness, determine elasticity, and detect a range of discontinuities, including corrosion/erosion, flaws, cracks, and more.

Coating thickness measurement is the determination of the layer depth of a coating or film on a particular substrate. Coating thickness can be measured when the film is wet or dry. However, non-destructive coating thickness measurement must be performed when the film or coating is dry.

4.An impact test which is useful for testing paint and coating adhesion is ASTM D2794, the drop test performed on a universal impact tester

This test is performed on cured rubber sheets per ASTM D2240, and on finished O-rings per ASTM D1414.
