23、9 For purposes of determining conformance with thisgeneral requirements specification and the applicable productspecification, values are to be rounded to the nearest unit in theright-hand place of figures used in expressing the limitingvalues in accordance with the rounding method of PracticeE29.1.
24、10 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith t
