5、700, and C72900, shallbe as prescribed in the current edition of Specification B740.1.3 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; therefore, each system shall be used independently

6、 of the other. Combining values from thetwo systems may result in non-conformance with the standard.2.
