Actual metrological and legal issues of non-destructive testing

摘要

The article is devoted to analyzing problems of metrological support and legal regulation in the sphere of non-destructive testing (NDT). Differences between the measurement technique and NDT have been analyzed. The necessity to apply the principles of metrological traceability to the NDT technique, equipment and test pieces has been announced. It has been suggested to view NDT as multi-parameter measurements. An example of the reference measuring system for complex calibrations of metal coatings measures on metal bases to calibrate eddy-current thickness gages of coatings has been given.
