5、cceptance criteria for inclusion of new aluminum and aluminum alloys and their properties in this specification, seeAnnex A1 and Annex A2.1.6 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard. The values statedin each system may not be exact equi
6、valents; therefore, each system shall be used independently of the other. Combining valuesfrom the two systems may result in nonconformance with the standard.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use.
