scope:

This Standard specifies a standard test method for determining the ability of metallic sheets mainly having a thickness from 0.1 mm up to 2 mm and a width of 90 mm or greater to undergo plastic deformation in stretch forming, using the said metallic sheets as a standard test piece.

The test method may be applied to test pieces thicker or narrower than the standard test piece shown in Table 2.

NOTE The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.
