Alternative quality - conformance provisions. Alternative quality conformance provisions, methods, or equipment, such as statistical proc
42、ess control, tool control, other types of Sam- pling procedures, etc. may be used by the contractor when they provide as a minimum the level of quality assurance required by the provisions specified herein. Prior to applying such alterna- tive procedures, methods, or equipment, the Contractor shall
43、describe them in a written proposal submitted to the Government for evaluation (see 6.7). When required, the contractor shall demonstrate that the effectiveness of each proposed alternative is equal to or better than the specified quality assurance provision(s) herein. In cases of dispute as to whet
44、her the con- tractors proposed alternative(s) provides equivalent assurance, the provisions of this specification shall apply. All approved alternative inspection provisions shall be specifically incor- porated into the contractors quality program or detailed inspection system, as applicable. 9 Prov
