This standard is a material used to apply significantly higher stress in the direction of the plate thickness among the main structural materials of steel structures. It classifies steel plates with a thickness of 13 mm or more and flat steel with a thickness of 13 mm or more and a width of 180 mm or more according to ultrasonic inspection tests. and judgment criteria are specified. In addition, general matters other than those specified in this standard follow KS B 0817.?
