11、 QUALITY ASSURANCE PROVISIONS 4.1 General quality assurance provisions. Unless otherwise specified in the contract. or purchase order, the supplier is responsi- ble for the performance of all inspection re- quirements as specified herein. Except as otherwise specified, the supplier may utilize his o
12、wn facilities or any commercial labora- tory acceptable to the Government. The Gov- ernment reserves the right to perform any of the inspections set forth in the specifica- tion where such inspections are deemed nec- essary to assure supplies and services con- form to prescribed requirements. Refere
13、-me shall be made to Standard MIL-STD-109 in order to define terms used herein, The provi- sions of Specification MILA-2560 shall ap Ply* 4.1.1 Subtnhsion of product. At the time the completed lot of product is submitted to the Government for acceptance the contrac- tor shall supply the following in
14、formation accompanied by a certificate which attests that the information provided is correct and applicable to the product being submitted: (a) A statement that the lot complies with allof the quality assurance provisions specified within this specification. (b) Number of units of product in- I spe
15、cted. _ (e) Results obtained, by defect code, for all inspections performed.

Using the contractors written quality assurance pro- cedure, this detail specification, the applica- ble d
19、rawings and other contractual docu- 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 compli- ance with the contractual reqliirements. Severit
20、y of Government inspection of in- dividual characteristics will be directly re- lated to the seriousness of the classification assigned. In no instance will a characteristic classifie4 “critical” be accepted solely on the basis of the contractors records . 4.2 Inspection provisions. 4.2.1 Lot fol-ma
21、tion. A lot shall consist of primers produced by one manufacturer in one unchanged process, in accordance with the same drawing, same drawing revision, same specification and same specification re- vision. Drawing, specification, and process changes not affecting safety, performance, or fit, as dete
22、rmined by the Government, shall not necessitate changing the lot inter- fix number. Lots shall be submitted for in- spections in accordance with Standard MIL STD-105 (or Standard MIL-STD-1235 when applicable). Each lot shall contain : . -. (a) Parts bearing the same lot interfix number from one manu
23、facturer. (b) Primer mixture from one batch or blending of batches which results in homogeniety of all primer mixture used in loading the en- tire primer lot. 4.2.2 Examination. Sampling plans and procedures for the following classifications of defects shall be in accordance with Stand- ard MIL-STD-
24、105 except that inspection for critical defects, when listed, shall be 100 percent. Continuous sampling plans in ac- cordance with Standard MILSTD-1235 may be used, for defects other than critical, if aproved by the procuring activity. Also, at the option of the procuring activity, AQLs m-3 tiamplin
25、g plans may be applied to the individual characteristics listed using an AQL of 0.40 percent for each major defect and an AQL of 0.65 percent for each minor defect.

Portions of the saturated solution shall be filtered be- fore use. 4.3.2.2.2. Procedzwe. A portion of approxi- mately 1 gm
37、 of the sample shall be ac- curately weighed directly into a tared 30 ml sintered glass crucible of medium porosity. A 6.0 mi portion of 1 percent nitric acid shill be added, and the crucible constantly swirled for 1 minute, in order that all the ingredients of the powder except antimony sulfi3e be
38、dissolved. Care shall be taken that none of the liquid be spilled. The mix- ture shall be filtered by applying suction. employing a vacuum flask. The crucible shall be removed from the adapter, and the bot- tom wiped dry with tissue paper. The wash- ing operation shall be repeated, using 6.0 ml of 1
39、 percent nitric acid each time, and the contents swirled for exactly I minute. After a total of 40 mi of 1 percent nitric acid has been used, the crucible shall be removed, and the bottom of it washed with water. The funnel, the funnel adapter, and the vacuum flask shall be washed with water, and th
40、e filtrate and washings discarded. About 1 mi of a saturated solution of ferric am- monium sulfate shall be placed in the flask. The contents of the crucible shall be treated 8 as before with 6.0 ml of 1 percent nitric acid, and filtered by means of suction into the flask. If the liquid in the flask
41、 turns red, due to the presence of the thiocyanate ion in the filtrate, the washing of the contents in the crucible shall be repeated with addi- tional 6.0 mi portions of 1 percent nitric acid, until a negative test for the thiocyanate ion has been affected. (Usually a total of 50 ml shall be suffic
42、ient.) The crucible and contents shall be rinsed with alcohol, and then with ether. The solution shall be as- pirated until the odor of ether can no longer be detected. The crucible and contents shall be dried in an oven at 80 degrees plus or minus 1 degree C. for 30 minutes, cooled in a desiccator,
43、 and weighed. The percentage of antimony sulfide shall be calculated as follows : A x 100 Antimony sulfide, percent = where : A = Weight of residue in the crucible.
