The parts under which the
7、 dotted lines are drawn are the matters not specified in the original Internatinal Standard. The outline of the difference in the specified contents In the original International Standard, the specimens are specified to be in accordance with IS0 9016, Welding - Welded joints in metallic materials -
8、Speci- men location and notch orientation for impact tests, for dimensions and testing. But IS0 9016 is not published yet, so that the specifications practical in our country at present are set forth in this Standard. 1 Scope test for butt welded joint mainly of steel materials.

If the thicknes
11、s of the steel material exceeds 28 mm, the test piece may be . taken from the deeper location 1/4 of thickness of steel material from the surface of steel material. If the thickness of steel material exceeds 50 mm, additional test piece shall be taken from the mid-thickness or in the root area of it
12、s neighbourhood. The direction of the longitudinal axis of the test piece shall be perpendicular to the weld line.
