Introduction:
1. Base metal characteristics:
For the magnetic method, the magnetism and surface roughness of the base metal of the standard sheet should be similar to the magnetism and surface roughness of the base metal of the test piece.
For the eddy current method, the electrical properties of the base metal of the standard sheet should be similar to those of the base metal of the test piece.
2. Base metal thickness:
Check whether the base metal thickness exceeds the critical thickness, if not, use the method described in the precautions to calibrate.
3. Edge effect:
Measurements should not be made in close proximity to sudden changes in the specimen, such as edges, holes, and inside corners.
4. Curvature:
Measurements shall not be made on the curved surface of the test piece.
5. Number of readings:
Often several readings must be taken within each measurement area because each reading of the instrument is not exactly the same. Local differences in overlay thickness also require multiple measurements within any given area, especially when the surface is rough.
6. Surface cleanliness:
Before measurement, remove any adhering substances on the surface, such as dust, grease and corrosion products, but do not remove any covering substances
