In the event of any conflict between the requirements of this specification and the specification sheet, the latter shall govern. 3.2 Description. Cable assemblies shall consist of cables, connecto
22、rs, dummy connectors, adapters, and terminal lugs and shall be as shown on figures 1 through 46 and applicable specification sheets. Dimensions and tolerances are shown where required. Where tolerances are not shown or where those prescribed could result in incorrect fits, the contractor is responsi
23、ble for providing tolerances to insure correct fit, assembly, and operation of each assembly. No deviation from dimensions or tolerances shown on the figures is permissible without prior approval of the contracting officer. 3.3 First article. When specified (see 6.2), a sample shall be subjected to
24、first article inspection in accordance with 4.2. 3.3.1 First article sample. The contractor shall furnish two cable assemblies of each type supplied for examination and test within the time frame specified (see 6.2) to prove prior to starting production that his production methods and choice of desi
25、gn detail will produce cable assemblies that comply with the requirements of this specification. Examination and tests shall be as specified in section 4; and, unless otherwise specified herein, all examinations and tests shall be conducted by the contractor subject to surveillance and approval by t
26、he Government (see 6.3). When specified (see 6.2), the Government will conduct any or all of the first article examination and tests (see 6.2).
