See Section 6 of MIL-A-48078 and 6.2 herein. 4.5 Test Methods and Procedures 4.5.1 Determination of Binder-Lubricant Content of Tetryl.-The binder-lubricant content of the tetryl shall. be determined for each b
29、atch or blend of batches at the time of loading. A sample of twenty (20) grams shall be selected and tested as specified in 4.5.1.1. If the binder-lubricant content is in excess of the percentage specified, the lot of tetryl shall be rejected and all detonators loaded with questionable tetryl shall
30、be rejected. 4.5.1.1 An accurately weighed portion of five (5) grams shall be transferred to a tared medium porosity sintered glass crucible. The sample shall be extracted with four 10 milli- liter (mi.) portions of acetone, maintaining each portion in contact with the residue for approximately five
31、 (5) minutes before applying suction. Any lumps which may persist shall be broken up and the sides of the crucible washed down with each 10 ml. portion of acetone to insure complete removal of the tetryl. The residue shall be aspirated until the odor of ace- tone is no longer detectable. The crucibl
32、e and contents shall be placed in a drying oven at 95 degrees Centigrade plus or minus 5 degrees C. for 1/2 hour, cooled in a desiccator and weighed. The above extraction shall be repeated, drying and weighing with individual 10 ml portions of acetone until the loss in weight on subsequent extractio
33、ns totals less than 0.005 gram. The percent of binder-lubricant content of tetryl shall be calculated as follows: Percent total binder-lubricant = (100) W A = Weight of crucible and sample before extraction B = Weight of crucible and sample after extraction W = Weight of the sample 18 Provided by IH

The percent moisture of th
37、e primer mixiare shall be calculated as follows: A sample of 3 grams 4.5.3.1 An accurately weighed 0.7 gram portion of the Percent moisture = e (100) W A = Weight of sample before drying B = Weight of sample after drying W = Weight of sample 4.5.4 Composition of Primer Mixture.-The composition of A

41、5 degrees C. plus or minus 2 de- grees C., agitated for exactly l minute, and if necessary, any lumps shall be broken up with a glass rod, taking care not to disturb the asbestos mat. Suction shall be applied. This pro- cedure shall be repeated five times, making a total of six ml. extractions. The
42、sample shall be rinsed in the filtering crucible with a few ml. of alcohol and ether; dried for approxi- mately 15 minutes at 95 degrees C. plus or minus 2 degrees C., cooled in a desiccator, and weighed. The percent of potassium chlorate should be calculated as follows: Percent chlorate = A-B - (10

44、(hot saturated ammonium acetate solution must not be used as it dissolves antimony sulfide to some extent) each portion being agitated for about 30 seconds, until the washings no longer give a yellow precipitate with a few drops of potassium dichromate solution. The use of more than 60 ml. of ammoni
45、um acetate solution should be avoided. The residue shall be washed with distilled water, rinsed with a few ml. of alcohol and ether, dried for approximately 15 minutes at 95 degrees C. plus or minus 5 degrees C., cooled in a desiccator and weighed.
