ASTM E376-2019 "Standard Practice for Measuring Coating Thickness by Magnetic-Field or Eddy Current (Electromagnetic) Testing Methods"

The ASTM E376-19 standard specifies a nondestructive Measuring method for Coating thickness using magnetic Induction and eddy current thickness gauges. The magnetic Induction method is suitable for nonmagnetic coatings on magnetic substrates, while the eddy current rule is used for coating measurement on conductive substrates. The standard emphasizes the influence of instrument selection, calibrating, and operating conditions on Measurement accuracy, and states that under ideal conditions, Coating thickness measurement errors can be within +/- 10%. This standard applies to Coating thickness measurement on metal substrates and complies with international standards.
