QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in t
17、he contract or purchase order (see 6.2.1), the contractor is responsible for the performance of all inspection requirements as specified herein. Except as other- wise specified in the contract or purchase order (see 6.2.1), the contractor may use his own or any other facilities suitable for the perf
18、ormance of the inspection requirements specified herein, unless disapproved by the Govern- ment. The Government reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to assure supplies and services conform to prescribed requir
19、ements. 4.1.1 Responsibility for compliance. All items must meet all requirements of sections 3 and 5. The inspection set forth in this specification shall become a part of the contractors overall inspection system or quality pro- gram. The absence of any inspection requirements in the specification
20、 shall not relieve the contractor of the responsibility of assuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling in quality conformance does not authorize submission of known defective material, either indicated or ac
21、tual, nor does it commit the Government to acceptance of defective material. 4.2 Quality conformance inspection. The material shall undergo the tests specified in 4.3. When specified in the contract (see 6.2), the contractor shall prepare a report giving the results obtained for all inspections and
22、tests performed and a certified statement that the lot meets all the requirements of this specification. Unless otherwise specified, all chemicals shall be ACS grade in accordance with MIL-STD-1218. Distilled water shall be used. Where applicable, blank determinations shall be run and corrections ap
23、plied where significant. 4.2.1 Lot size. A lot shall not exceed 4.54 metric tons. 4.2.2 Sampling. A minimum of 10 percent of the containers in a lot shall be selected so as to be representative of the lot. When less than 100 containers comprise a lot, either 10 containers or all the containers in th
24、e lot shall be sampled. Using a thief or scoop, remove sufficient material to give a primary sample of approximately 250 grams (g) from different parts of each container. Mix the sample thoroughly and place a 125 g portion in a bottle labeled so the container from which the sample was taken can be i
25、dentified. The remainder of each sample shall weigh approximately 125 g. Mix these thoroughly and quarter until a composite sample of about 250 g is obtained. Place the composite sample in a rubber-stoppered bottle and label so as to show the name of the material, manufacturer, plant, contract or or
26、der number, number of kilograms in the lot and the lot number. All acceptance tests shall be made on the composite sample. The primary samples shall be held for possible future examinations should the composite sample fail to meet requirements. 4.3 Test methods. 4.3.1 Oxalate purity. Transfer 0.300
27、g of the sample to a 600-milliliter (mi) beaker and add 200 ml of 9 per- cent sulfuric acid which has been previously boiled for 10 to 15 minutes and then cooled to 27“ f 3C. Stir the mixture until the oxalate has dissolved. Add 39 to 40 ml of 0.1N potassium permanganate solution, over a period of 1
28、 minute, while stirring slowly. Allow the solution to stand until the pink color is dispelled. If the pink color persists for several minutes, too much permanganate was added. In this case, discard the determina- tion and start another. Add a few ml less of permanganate solution. After the pink colo
29、r disappears, heat the solution to 55“ to 60C and complete the titration by adding the standardized permanganate until a faint pink color persists for 30 seconds. Add the last 0.5 to 1 mi dropwise, taking care to aliow each drop to become decolorized before the next is introduced. Determine the exce
30、ss of permanganate required to impart pink coloration to the sample solution by titrating a blank consisting of the same volume of the specially treated dilute sulfuric acid solution at 55“ to 60“C, to a finish coloration matching that of the titrated solution of the sample. Calculate the percentage
31、 of sodium oxalate in the sample on a moisture free basis as follows: 6.7 (V)N W Percent sodium oxalate = where: V = corrected volume of permanganate solution used in the titration, ml N = normality of permanganate solution W = weight of the dry sample, g 3 Provided by IHSNot for ResaleNo reproducti
32、on or networking permitted without license from IHS-,-,-MIL-S-210A 4.3.2 Moisture. Transfer approximately 5 grams of the sample to a weighing bottle and weigh accurately. Dry the sample for 1 hour at 105“C, cool in a dessicator and weigh. Percent moisture = A - B x 100 W where: A = weight of the wei
33、ghing bottle plus sample before heating, g B = weight of bottle plus sample after heating, g W = weight of sample, g 4.3.3 Sodium acid oxalate. Dissolve a weighed portion of approximately 10 g of the sample in 350 ml of hot recently boiled distilled water, Titrate the hot solution with O. 1N sodium
34、hydroxide solution, using phenolthalein as the indicator. Calculate the acidity as percentage of sodium acid oxalate as follows: O g of the sample in 1 Percent sodium acid oxalate = 11.2 (V)N W where: V = ml of sodium hydroxide solution used, ml N = normality of sodium hydroxide W = weight of sample
35、, g 3.4 Insoluble matter. Dissolve a weighed portion of approximate-j O0 ml of distilled water at room temperature. Filter the solution using a tared filtering crucible and wash the residue with 100 ml of distilled water. Heat the crucible and residue for 1 hour at 105“C, cool in a dessicator and we
36、igh. Percent insoluble matter = C - D X 100 W where: C = weight of crucible and residue, g D = weight of crucible, g W = weight of sample, g 4.3.5 Granulation. Place an accurately weighed portion of approximately 100 g of sample on the specified nest of sieves properly superimposed and assembled wit
37、h a bottom pan. Place a metal washer on each of the sieves, cover and shake for 10 minutes by hand or 5 minutes by means of a mechanical shaker geared to produce 300 f 15 gyrations and 150 f 10 taps of the striker per minute. Weigh the portions retained or passed by the various sieves and calculate
38、the results on a percentage basis as required. 4.4 Submission of material safety data sheets. The contractor shall furnish to the contracting activity the tox- icological data and formulation required to evaluate the safety of the material for the proposed use through the submission of the Material
39、Safety Data Sheets detailed in FED-STD-313 (see 3.3 and 6.2). 5. PACKAGING 5.1 Packaging. Unless otherwise specified, the material shall be packaged in accordance with the manufac- turers best accepted commercial practice. 4 Provided by IHSNot for ResaleNo reproduction or networking permitted withou
