6、ch-poundunits.1.5 Specification A336/A336M formerly included austenitic steel forgings, which are now found in Specification A965/A965M.1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents

7、; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.7 This international standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision
