Sample Selection Connector housings and contacts shall be prepared in accordance with applicable Instruction Sheets and shall be selected at random from current production. Test group 1 shall consist of 1 connector of each size, all representative of the entire lot being tested. Test groups 2 through 6 shall consist of 2 connector assemblies per group per wire size. Test group 7 shall consist of 15 contacts chosen randomly from 5 connector assemblies. Test group 8 shall consist of 4 connector assemblies per wire size. Each wire size shall consist of solid, stranded and prefused or overcoated wire; UL style 1007 or 1061 tin plated. Stranded wire shall consist of 7 strands. All wires shall be applied in accordance with Application Specification 114-1020. Complete qualification of the product line can be accomplished by sampling the product using all variations of wire size, type and connector design. Partial qualification can be accomplished by using only one variation of wire size, type or connector design. B.
