31、rity is vested in another agent of the certifying organization. The initial certificate submitted shall be substantiated by evidence 4.1.2 Government Verification. Using the contractors written quality assurance procedure, this detail specification, the applicable drawings and other contractual docu
32、ments as a guide, the government inspector shall verify at unscheduled Intervals all quality assurance operations performed by the contractor. Verification will be performed to the extent necessary to assure compliance with the contractual requirements. Severity of government inspec- tion of indlvid

34、 Prior to the start of regular production, the contractor shall submit a preproduction sample to a government approved facility as designated by .the Contracting Officer (see 6.3) for evaluation in accordance with the provisions of 4.1.3.2. The preproduction sample shall consist of five spools which
35、 have been produced by the contractor or furnished by a supplier and which have been manufactured using the same pro- duction processes, procedures and equipment which will be used in fulfilling the contract. All materials, including packaging and packing, shall be ob- tained from the same sources o
36、f supply as will be used in regular production. The sample shall be accompanied by certificates of conformance for materials. A preproduction sample, or portion thereof, as directed by the contracting officer, shall also be submitted whenever a change occurs in manufacturing process, material used o
37、r source of supply such as to significantly affect product uniformity as determined by the government. Prior to submission, the contractor shall inspect the sample to the degree necessary to assure that it conforms to the requirements of the contract and submit a record of this in- . spection with t
38、he sample. A sample containing known defects will riot be sub- mitted unless specifically authorized by the contracting officer. 4.1.3.2 Inspections to be Performed. The spools will be subjected by the government to any or all of the exaniiiations specified in this specifica- tion and any or all req
39、uirements of the applicable drawing. 4.1.3.3 Rejection. If any sample fails to comply with any or all of the applicable requirements, the initial production sample shall be rejected, The government reserves the right to terminate its inspection upon any failure of any component in the sample to comp
40、ly with any of the stated re- quirements. In the event of rejection, the government reserves the right to require the contractor to take corrective action and submit a new initial production sample or portion thereof. Until an initial production sample is accepted, the contractor is in no way author
41、ized by the government to initiate regular production unless otherwise directed by the Contracting Officer. 4.2 Inspection Provisions. 4.2.1 Lot Formation. A lot size shall not exceed that quantity of detonating cord produced in one continuing process using one lot of explosive and one lot of sheath
42、ing material. The sample selected shall represent only that quantity of units from which the sample was drawn and shall not be con- strued to represent any prior or subsequent quantities presented for inspec- tion. produced by one manufacturer, in one unchanged process, in accordance with the same d

44、ll be numbered in accordance with MIL-STD-1168. Unless otherwise approved by the Contracting Officer, the inspection lot size of major assemblies or end items deliverable under the contract shall be not less than the smallest weekly estimate of quantities contractually scheduled for production durin
45、g the contract period nor more than the largest quantity contractually scheduled for delivery during any month of the contract period. Homogeneity shall be considered to exist provided the lot has been Inspection lots shall 7 Provided by IHSNot for ResaleNo reproduction or networking permitted witho

Sampling plans and procedures for major and minor defects shall be in .accordance with ML-STD-105 except that continuous sampling plans in accordance
47、 with MIL-STD-1235 may be used if approved by the procuring activity. 4.2.3 Testinq. 4.2.3.1 General. The contractor shall make available to the government all inspection equipment necessary for determining conformance with contract requirements. Personnel for operating the equipment and verificatio
48、n of its accuracy, shall be supplied by the contractor for the performance of examina- tion or test by the government. 4.2.3.2 Sampling. Visual Inspection. Unless otherwise specified visual inspection shall be performed on all samples. 4.2.3.3 Testing. Unless otherwise specified acceptance tests sha
49、ll be performed on 110 feet of the production lot of detonating cord. Test samples shall be chosen at random in as much as possible and cut to the size required for individual tes t. 4.2.3.4 X-Ray Examination.
