1 Scope This standard specifies term of an agreement for steel forgings-ultrasonic testing, editing of operation specifications, staff qualification, equipment, and appendix, calibration and checking, testing time, surface condition, sensitivity, scanning, classification, recording level and acceptance standard. This standard is applicable to ultrasonic pulse-echo handiwork test method for Ferritic-Martensitic steel forgings, Austenitic and Austenitic- Ferritic stainless steel forgings. By the negotiation between the parties, it may also use mechanization scanning method with immersion method testing. Other organizational forgings may also be used by referring to. This standard divides forgings into 4 types according to shapes and manufacturing methods. Types 1, 2 and 3 are forgings with simple shape and type 4 is forgings with complicated shape. This standard is not applicable to compact stamp work, turbine rotor and engine forgings. 2 Normative references The following normative documents contain provision which, through reference in this text, constitute provisions of this national standard. For dated reference, subsequent amendments to, or revision (excluding error content) of, any of these publications do not apply. All standards are subject to revision, and parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
