In any case, not less than 10 containers shall be selected to represent the lot. The supplier shall be given n

18、o prior information to indicate which particular containers will be se- lected. A representative i-pound primary sample shall be taken from each selected container. Each primary sample shall be mixed thoroughly, divided into two 8-ounce portions, and transferred to. approved sample containers so lab

19、eled that the shipping contain- ers from which these primary samples were taken can be identified readily. One 8-ounce portion shall be taken for laboratory exami- nation and the other 8-ounce portion shall be retained for possible check analysis. Spot check samples shall be taken from time to time,

20、 from any portion of the lot, by the Government inspector. F-2b. Composite sample basis.-When acceptance on basis of primary sample analysis is not feasible or advisable in the opinion of the Government inspector, the acceptance tests shall be made on a composite sample prepared by mixing a blend of

21、 equal ortions taken from each of the primary samples and reducing the lend to obtain a composite sample weighing approximately 1 pound. The remaining portions of the primary samples shall be held by the Government inspector for possible future examination should the composite sample fail to meet th

24、e sampIes selected to represent the lot. No lot shall be accepted when the analysis of any primary sample or the composite sample shows noncompliance in any respect with any requirement of this specification. Spot check samples taken from any portion of the lot shall comply with the requirements of

27、ance with the following paragrapis. For Navy purchases, the tests shall be made at a Government laboratory unless otherwise speci- fied in the contract or order. F-4a. Volatile matter,-Dry an accurately weighed sample of approximately 5 gm, for ?4 hour in a desiccator containing con- centrated H2S04

28、 and evacuated to an absolute pressure of not more than 360 mm. nor less than 100 mm. of mercury. The desic- cator shall be equipped to prevent the sample from coming into contact with the HISO,. Calculate the loss in weight of the sample as percentage of volatile matter. F-4b. Composition,- F-4b (1

29、). Saturated PETN solution.-Prepare a saturated soh- tion of PETN in chloroform at least 24 hours before use. The saturated solution shall be in contact with excess PETN. The portion of the saturated solution required for use shall be filtered just before the determination is made to assure saturati

30、on at the temperature at which the analysis is conducted. F-4b (2). Procedure.-Transfer an accurately weighed portion of approximately 6 gm. of the sample to a tared, 30 ml. sintered glass crucible of medium porosity. Place the crucible on a filter adapter without suction. Add 10 ml. of the saturate

31、d PETN in chloroform solution. Allow to stand for 1 minute, then apply suc- tion until the filtrate ceases to drip, and release the suction. Re- peat to a total of five extractions. On the final extraction, hold the suction for a period of greater than 1 minute in order to as- pirate. Dry to constan

32、t weight in a looo C. oven and calculate the gain in weight as percentage of PETN. The percentage of TNT is found by subtracting from 100, the sum of the percentages of PETN and volatile matter. F-4c. Acelmze insoluble (total).-Dissolve a weighed portion of approximately 10 gm. of the sample in 50 n

33、il. of acetone, boiling gently on a steam bath iintil solution is complete. Decant through a tared filtrring crucible, transferring all insoluble niatter to the crucible. Wash the latter with hot acetone, dry at 100“ C. for 3 hours, cool in a desiccator and weigh. Calculate the gain in weight as per

34、centage of acetone insoluble material. Fad. Acetone iiisohcble (inorgnnicc).-This test need not be made if the acetone insoluble (total), paragraph F-c, is less than 0.02 percent. Heat the crucible with insoluble residue (par. F-le) over a Bunsen burner to remove all organic matter, cool in a dcsic-

35、 cator and weigh. Calculate the weight of the residue in the cru- cible as percentage of inorganic matter. F-4e. Acidity or alkaliniy.-Stir a weighed portion of approxi- mately 10 gm. of the sample vigorously with 50 ml. of Uui!ing distilled water, until, as the mixture coois, the TNT granulates. Wh

36、en cool and the PETN has settled, decant off the supernatant liquid and extract tlic iiiaterial with an additional 50 ml. of boil- ing distilled water. Repeat the stirring, cooling, settling and de- cantation. Titrate the combined aqueous extracts with N/50 so- dium hydroxide or sulfuric acid using

37、niethyl red as the indicator. Correct the result by means of a b!ank determination.

Pour on a U. S. Standard NO. 120 sieve, transfer all remaining insoluble material to the sieve and wash with
