8、applications, reference should be made to SpecificationA320/A320M.1.4 Nuts for use with bolting are covered in Section 14.1.5 Supplementary Requirements are provided for use at theoption of the purchaser. The supplementary requirements shallapply only when specified in the purchase order or contract

9、.1.6 This specification is expressed in both inch-pound unitsand in SI units; however, unless the purchase order or contractspecifies the applicable M specification designation (SI units),the inch-pound units shall apply.1.7 The values stated in either SI units or inch-pound unitsare to be regarded

10、separately as standard. Within the text, theSI units are shown in brackets. The values stated in eachsystem may not be exact equivalents; therefore, each systemshall be used independently of the other. Combining valuesfrom the two systems may result in non-conformance with thestandard.2. Referenced
