The ASTM B499-09 (2021) e1 standard describes a method for nondestructive measurement of non-magnetized Coating thickness on magnetic substrate metals by magnetic instrumentation. This method utilizes magnetic attraction or changes in flux density within the probe to evaluate the cumulative thickness of coatings, not for electrolysis deposited nickel coatings. The standard is suitable for specification acceptance and quality control applications for a variety of coatings, ensuring that the test results meet the requirements of the ISO 2178 standard. This method is suitable for use as a supplement to the manufacturer's operating instructions, but is not a substitute for Miscellaneous measurement techniques.
