In our December 2013 Editorial(1), we reported that with regard to penetrant testing (PT) and magnetic particle testing (MT), there were some differences between the EN/ISO standards and the ASTM E1316 standard and we provided some examples.

Other differences exist, mainly about the name and the abbreviated term of some NDT methods, as shown in the following table.

ISO 9712:12
ASTM E 1316-14
NDT methods
Abbreviated terms
NDT methods
Abbreviated terms
Infrared thermographic testing
TT
Infrared testing
IRT
Eddy current testing
ET
Electromagnetic testing
ET
Magnetic testing*
MT
Magnetic particle testing
MT
Penetrant testing
PT
Liquid penetrant testing
PT
Radiographic testing
RT
Gamma- and X-radiologic testing
RT

* There is a mistake because the word « particle » is missing. It shall be written « Magnetic particle testing ».

It would be so better to use the same names for the NDT methods and the same relevant abbreviated terms in order to rely upon only one terminology worldwide.

Sometimes, in French, the term “TT” is erroneously used as a short term for “Toutes Techniques” (i.e. "All Techniques" in English), which should not be done to avoid any confusion with "Infrared thermographic Testing”?
