適用范圍：1.1 This standard prescribes notched tensile and notched bend tests for assessing the quality of butt welds in steel sheet, plate and pipe and bend over test and wedge test for assessing the quality of fillet welds in steel plate.1.2 Notched tensile test included in this standard is applicable to steel sheet, plate and pipe of thickness up to and including 20 mm. The bend over and wedge tests are applicable to steel plates of thickness between 5 to 12 mm.1.3 These tests could be used in lieu of only those tests which are used for assessing similar qualities, and are not meant for replacing all the tests specified in the various codes. For example, where radiographic tests, or fillet weld shearing tests to ascertain the strength of the joint are specified, these will have to be done in addition to the tests specified in this standard.
