scope:

This standard describes techniques for the manual, pulse-echo,ultrasonic testing of forgings manufactured from austenitic andaustenitic-ferritic stainless steels. Mechanized scanningtechniques, such as immersion testing, may be used but should beagreed between the purchaser and supplier (see Clause 4). This partof EN 10228 applies to four types of forgings, classified accordingto their shape and method of production. Types 1, 2 and 3 areessentially simple shapes. Type 4 covers complex shapes. This partof EN 10228 does not apply to: ? closed die forgings; ? turbinerotor and generator forgings. Ultrasonic testing of ferritic andmartensitic steel forgings is the subject of Part 3 of thisstandard.
