6、on.1.4 This standard is a combined standard,an ASTM stan-dard in which rationalized SI units and inch-pound units areincluded in the same standard,with each system of units to beregarded separately as standard.1.4.1 UnitsThe values stated in either SI units or inch-pound units are to be regarded sep
7、arately as standard.Thevalues 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.1.5 This standard does not purport to address all of thesafety concern
