This European Standard describes techniques for the manual, pulse-echo, ultrasonic testing of forgings manufactured from austenitic and austenitic-ferritic stainless steels. Mechanized scanning techniques, such as immersion testing, may be used but should be agreed between the purchaser and supplier (see Clause 4). This part of EN 10228 applies to four types of forgings, classified according to their shape and method of production. Types 1, 2 and 3 are essentially simple shapes. Type 4 covers complex shapes. This part of EN 10228 does not apply to: – closed die forgings; – turbine rotor and generator forgings. Ultrasonic testing of ferritic and martensitic steel forgings is the subject of Part 3 of this European Standard.<\/p>\n
