1. Scope of application This standard applies to the use of single-frequency coil inside and outside the ferromagnetic and non-ferromagnetic pipe non-destructive testing. 2. Purpose This standard gives a general description of eddy current testing of pipe materials, describes and specifies the methods and techniques used in the remainder of this standard with the aim of unifying the application of methods and techniques. 3. Concepts The concept is quoted in DIN 54 140 Part I and Part II (now Draft). 4. Marks with through-coil single frequency (T1) test tube marking: Prüfung DIN 54 141-T15. Eddy current field generation
