19、ons are required by the purchaser,and apply only where specified individually in the purchaseorder.1.9 In case of any conflict in requirements, the requirementsof the applicable product specification prevail over those of thisgeneral requirements specification.1.10 Additional requirements that are s
20、pecified in the pur-chase order and accepted by the supplier are permitted,provided that such requirements do not negate any of therequirements of this general requirements specification or theapplicable product specification.1.11 For purposes of determining conformance with thisgeneral requirements
21、 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 PracticeE29.1.12 The text of this general requirements specificationcontains notes or
22、 footnotes, or both, that provide explanatorymaterial. Such notes and footnotes, excluding those in tablesand figures, do not contain any mandatory requirements.1.13 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard. Within the text, theSI units are sh
23、own in brackets. The values stated in eachsystem are not exact equivalents; therefore, each system is tobe used independently of the other, without combining valuesin any way.1.14 This general requirements specification and the appli-cable product specification are expressed in both inch-poundunits
24、and SI units; however, unless the order specifies theapplicable “M” specification designation (SI units), the struc-tural product is furnished to inch-pound units.1.15 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the

If the necessary tests required by a product specificationcannot be conducted, the product cannot be q
