Anotation

This test method deals with the procedures and acceptance standards for straight beam, pulse echo, ultrasonic examination of rolled structural shapes. The section surfaces shall be sufficiently clean and smooth to maintain a back reflection from the opposite side of the flanges, legs and webs. Ultrasonic testing shall be made on the major surface of each flange and one major web surface. Evaluation of indications may require inspection from an opposite surface. Two levels of acceptance standards are included. Level II is intended for normal applications where freedom from gross internal discontinuities is desired, particularly in connection regions. Level I is intended for critical applications such as welded chord members used in tension loading.
