22、 Order of precedence. In the event of a conflict between the text of thisdocument and the references cited herein (except for related associated specificationsor specification sheets), the text of this document takes precedence. Nothing in thisdocument, however, supersedes applicable laws and regula
23、tions unless a specificexemption has been obtained.3. REQUIREMENTS3.1 Specification sheets. The individual item requirements shall be as specifiedherein and in accordance with the applicable specification sheet. In the event of anyconflict between the requirements of this specification and the speci
24、fication sheet,the latter shall govern.3.2 Qualification. Fiber optic splices furnished under this specification shall beproducts that are authorized by the qualifying activity for listing on the applicablequalified products list before contract award (see 4.5 and 6.3). The provisions of4.5.4 for re
25、tention of qualification are included in this requirement.3.3 Materials. The splice shall be constructed of materials as specified herein andin the specification sheet (see 3.1).
