In ISO 17643 2005: Eddy current testing can be used to detect surface cracks through non-metallic coatings up to _______ mm thick. For coating thicknesses greater, the sensitivity of the test method shall be demonstrated in advance before eddy current testing is used.
|
[STD] |
| a) 0,5 mm | ||
| b) 1,0 mm | ||
| c) 2,0 mm | ||
| d) 4,0 mm | ||
| 8 |
It should be noted that some types of conductive coating, such as thermally sprayed aluminium and lead, can seriously influence the results as they can deposit electrically conductive metallic material in cracks open to the surface. Cracks covered with such a metallic deposit are not always indicated by this method.
