25、Submission. - Prior to the start of regular produc- tion the contractor shall submit a first article sample (see 6.1) to a Government approved facility as designated by the contracting officer for evaluation in accordance with the pro- visions of 4.2.2. The first article sample shall consist of comp

26、onent parts, sub-assemblies and assemblies which have been produced by the contractor or furnished by a supplier and which have been manufactured using the same production processes, pro- cedures and equipment which will be used in fulfilling the con- tract. All parts and materials, including packag

27、ing and packing components, shall be obtained from the same source of supply as will be used in regular production. 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 he shall submit a record of thi

28、s inspection with the sample, including certificates of conformance of materials. A sample containing known defects shall not be submitted unless speci- fically authorized by the contracting officer. A first article sample, or portion thereof, as directed by the contracting of- ficer shall also be s

29、ubmitted whenever there is a lapse in pro- duction for a period in excess of 90 days, or whenever a change occurs in manufacturing process, material used, drawing or speci- fication such as to significantly affect product uniformity as determined by the Government. In the event of rejection, the Gov

30、ernment reserves the right to require the contractor to take corrective action and submit an additional sample or portion thereof of items for first article inspection. Until that phase of the first article sample consisting of parts, and firing de- vices is accepted, the contractor is in no way, au

31、thorized by the Government to initiate regular production unless otherwise directed by the contracting officer. 4.2.2 First Article Inspection Provisions 4.2.2.1 Component parts and Subassemblies 4.2.2.1.1 Submission. - Twenty-five (25) complete sets of parts (5.e. 25 each of every component part an

32、d subassembly, including at least three (3) items from each cavity used to produce plastic parts and be so identified as to permit tracing each item to the cavity in which it was molded).

33、 W 97777060337683 O W MIL-F-LC8235 (MU) - 4.2.2.1.2 Inspections to be performed. - The parts and sub-assemblies will be subjected by the Government to any or all of the applicable examinations and tests specified in 4.3.2, 4.3.3 and 4.3.5 of this specification and any or all of the requirements of t

34、he applicable drawings. 4.2.2.1.3 Rejection. - If any component or subassembly fails to comply with any of the applicable requirements, the first article sample shall be rejected. The Government reserves the right to terminate its inspection upon any failure of a component or subassembly to comply w

35、ith any of the stated re- quirement s. 4.2.2.2 Firing Device Assemblies 4.2.2.2.1 Submission. - Thirty (30) test sets completely packaged and sealed as required by the applicable drawings. 4.2.2.2.2 Inspection to be performed. - The 30 firing device assemblies shall be subjected to the following tes

36、ts in the sequence indlcated in addition to the inspection of 4.3.2.18 : a. Air leak test (see 3.4) in accordance with the method specified in 4.4.2. b. Functioning at ambient temperature (see 3.5.1) in accordance with the method specified in 4.4.3. c. Functioning at cold temperature (see 3.5.2) in

37、accordance with the method specified in 4.4.3. 4.2.2.2.3 Rejection. - If any firing device fails to comply with any of the applicable requirements, the first article sample shall be rejected. The Government reserves the right to terminate its inspection upon any failure of the test set to comply wit

38、h any of the stated requirements. 4.3 inspection Provisions 4.3.1 Lot formation. - The term “inspection lot“ as used in this specification is defined as an essentially homogeneous collection of units of product from which a representative sample is drawn and inspected to determine conformance with a

39、pplicable requirements. Th sample selected shall represent only that quantity of units from which the sample was drawn and shall not be construed to represent any prior or subsequent 6 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-F-48235 (MU)

40、quantities presented for inspection. Homogeneity shall be considered to exist provided the inspection lot has been pro- duced by one manufacturer, in one unchanged process, using the same material and methods, in accordance with the same drawings, same drawing revisions, same specifications and same

41、 specification revisions and complies with the provisions for submission of product as specified in MIL-XTD-105. Changes to the process, specification, or drawing not affecting safety, performance, interchangeability, or storage, as determined by the Government, shall not be deemed to alter the homo

42、geneity of an inspection lot. All material submitted for inspection in accordance with this specification shall comply with the homogeneity criteria specified herein regardless of the type of sampling procedure which is being applied to determine con- formance with requirements. Lot numbering, as re

43、quired, shall be in accordance with MIL-STD-1168. Each inspection lot of firing devices shall contain parts from not more than one lot interfix number from one manufacturer. 4.3.2 Examination. - The examinations listed in the following subparagraphs shall be performed on inspection lots (see 4.3.1)

44、of the components or assemblies designated in the applicable paragraph headings. Inspection for critical defects (and major defects, when so specified) shall be 100 per- cent. Sampling plans for major and minor defects shall be in accordance with MIL-STD-105 except that continuous sampling plans in

45、accordance with MIL-STD-1235 may be used if approved by the Government. Instead of applying the AQLs designated herein to the groups of major and minor defects listed, the contractor may elect to apply AQLs to individual defects using an AQL of 0.40 percent for each major defect and an AQL of 0.65 p

46、ercent for each minor defect. When this method is elected, it shall be applied to all of the major and minor defects listed in the applicable subparagraph of this section, except where 100 percent inspection is specified, and be documented as part of the contractors inspection system. Equipment nece

47、ssary for the performance of the inspections listed shall be in accordance with 4.3.4. 4.3.2.1 Housing (see dwg. 8800936 covering a detail of dwg. 8837124).
