Sets out requirements for preparation of test pieces, procedures for performing test, and the preparation of a test report. Appendices include guidance on the calculation of 'r' values based on length and width measurements and describe three test procedures which may be used.

This standard sets out the method for the measurement of the plastic strain ratio 'r', of sheet and strip metals.
