Note 1: The original title of this standard was “Standard Test Method for Equotip Hardness Testing of Steel Products.”1

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
