Description / Abstract: This method describes the procedure to be used in determining the quality of the seam or helical, continuously welded seam, corrugated steel pipe. The procedure to be used involves distorting a short length of welded seam by using a 25-mm diameter, hemispherical punch and a 38-mm inside diameter contoured die. The resulting distorted weld area will hereafter be called the "cup."

At the option of the engineer, or in the event of a disagreement between the engineer and fabricator, the referee test described in Section 4 will be performed.
