    26、ensitic steel. 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 es

    27、sentially 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 austenitic and austenitic-ferritic stainless steel forgings is the subject of EN 10228-4. 2 Normative references The follow

It shall be manufactured from one of the following: a) an excess length of the object to be tested; b) a part of the same material and with the same heat treatment condition as the object to be

    48、 tested; c) an object having similar acoustic properties to the object to be tested. Reference blocks shall not be used for the distance-gain-size (DGS) technique unless it is required to check the accuracy of a particular DGS diagram. The sizes of reflectors in the reference block are governed by t

    49、he sizes detailed in Tables 5 and 6 as appropriate. Different sizes of reflectors from those detailed in Tables 5 and 6 may be used provided the test sensitivity is corrected accordingly. 7.5 Couplant The couplant used shall be appropriate to the application. The same type of couplant shall be used for the setting of range and sensitivity, for scanning and for the assessment of discontinuities. NOTE Examples of suitable cou
