Eddy Current Standards and Methods

Standards

British Standards (BS) and American Standards (ASTM) relating to magnetic flux leakage and eddy current methods of testing are given below. National standards are currently being harmonized across the whole of Europe, and British Standards are no exception. Harmonized standards will eventually be identified by the initials BS EN; for example, BS 5411 has been revised and is now known as BS EN 2360. Harmonization is unlikely to be completed before 2001. The year of updating a British Standard is given in brackets. ASTM standards are published annually and updated when necessary.
