This standard describes the test method for the measurement of internal stress in metallic coatings using a spiral cissing meter. Helical cissing meters can provide results of repeatability over a wide range of stresses, helping to specify stress limits for Eletroplating or electroformed parts, thereby controlling internal stress in the production process. These internal stresses affect the fatigue strength, corrosion resistance, dimensional Stability and cracking, disbonding properties of coatings. The standard describes the relationship between test conditions and actual stress values of coated parts, and emphasizes the accuracy of test results when factors such as Coating thickness and substrate preparation are consistent.
