Active Standard: A262 - 13
Revise A262E paragraph 30.1 as follows: 30.1 The test specimen shall be bent through 180 and over a diameter equal to the thickness of the specimen being bent (see Fig. 10). In no case shall the specimen be bent over a smaller radius or through a greater angle than that specified in the product specification. In cases of material having low ductility, such as severely cold worked material, a 180 bend may prove impractical. Users shall inform those conducting the Practice E test when the material is in the low ductility highly stressed condition, such as highly cold worked material. Determine the maximum angle of bend without causing cracks in such material by bending an untested specimen of the same configuration as the specimen to be tested. After exposure to the acidified copper-copper sulfate sulfuric acid test solution, the maximum angle of bend without causing cracks as determined from untested low ductility specimens shall be utilized in evaluation of the specimens exposed to the acidified copper-copper sulfate sulfuric acid test solution. The angle of bend utilized in evaluating tested specimens shall be reported.
