WG 2 - Ultrasonic testing of steel flat products

This document describes a method for the ultrasonic-testing of uncoated flat austenitic and austenitic-ferritic stainless steel product for internal discontinuities.
This document is applicable to flat product in nominal thickness range of 6 mm to 200 mm.
This document also defines four quality classes for the flat product body (classes S1, SA, S2 and S3) and four quality classes (E1, E2, E3, E4) for the edges (see Clause 15).
A list of equivalent terms in several European languages is given in Annex A.

This document describes a method for the ultrasonic testing of uncoated flat steel product for internal discontinuities.
This document is applicable to flat product in nominal thickness range of 5 mm to 200 mm of non-alloyed or alloyed steel, excluding austenitic or austenoferritic steels. However, this document can be applied to the latter types of steels provided that the difference between the amplitude of the noise signal and that of the echo detection threshold is sufficient for the limit fixed.
This document also defines five quality classes for the flat product body (classes S0, S1, SA, S2 and S3) and five classes (E0, E1, E2, E3, E4) for the edges (see Clause 13).
Other methods of testing (e.g. by phased-array) or other test equipment may be used at the manufacturer's discretion provided that they give identical results to those obtained under the conditions of this document. In the event of a dispute, only the method defined in this document shall prevail.
Testing of flat product of thickness less than 5 mm or higher than 200 mm may be the subject of special agreements between the parties concerned.
The inspection is normally carried out in the place of production or on the premises of the supplier. If specified on the order, the inspection takes place in the presence of the purchaser or his representative1.
A list of equivalent terms in several European languages is given in Annex A.
