The first article of 50 Type I or 50 Type II leads shall be subjected to the inspections of Figure 1 in the sequence shown. At the conclusion of the inspection sequence and after receipt of first article approval, any rem
37、ains of the first article shall be disposed of at the discretion of the cognizant demolition officer. 4.2.2 First article, acceptance and rejection criteria, Each first article lead shall meet the requirements specified in the contract or purchase arder, on the drawings, and herein. For the inspecti
38、ons of Figure 1, the applicable requirements of Section 3 shall be met on the first and only trial; one or more failures shall be cause for refusal to grant first article approval. For the function and output test of 4.6.2, acceptance or rejection of the first article shall be based on the following
39、 criteria: a. A depth of dent of less than 0.075 inch from any Type I sample lead or less than 0.038 inch from any Type II sample lead, when measured in accordance with 4.6.2.3. shall be cause for rejection of the first article. b. The first article shall be accepted if the quantity (x-L)/s, when co
40、mputed in accordance with 4.6.2.3.d, is equal to or greater than the k value of MIL-STD-414, Table B-I, Accept- able Quality Level (AQL) of 0.65 percent defective. A quantity less than the k value shall be cause for rejection of the first article. 4.3 Quality conformance inspections. 4.3.1 Inspectio
41、n lot. As specified in the contract or purchase order, an inspection lot shall consist of completed Type I or Type II leads, fabricated under the same conditions and offered for acceptance inspec- tion at the same time (see 6.2.1). 4.3.1.1 Inspection lot size. The inspection lot size shall be as spe
42、ci- fied in the contract or purchase order (see 6.2.1). 4.3.1.2 Inspection lot acceptance inspection sequence. After the inspection lot has been formed and identified by lot number, the lot shall be subjected to the inspections of Figure 2 in the sequence shown. Where specified during the inspection
43、 sequence, a quantity of leads shall be randomly sampled from the inspection lot in accordance with MIL-STD-414 , Inspection Level IV, Standard Deviation Method, Variability Unknown. As the sample continues through the inspection sequence, the remainder of the lot shall be held in bond. If the sampl
44、e does not cause lot rejection (see 4.3.1.3), the remainder of the lot shall continue through the inspection sequence as shown on Figure 2. Upon completion of the inspection sequence, the remains of the sample leads shall be disposed of at the discretion of the cognizant demolition officer. 7 Provid
