Approximately 1 gram of the primer mixture shall be accu- rately weighed and transferred to a tared fil- terhg crucible of approximately 15 ml. capac- ity. Three ml. of lead azi
18、de-saturated distilled water hll be added at a temperature of 25 degrees C. plus or minus 2 degrees C., agitated for exactly 1 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 procedure shall be repea
19、ted five times making a total of six 3 ml. extractions. The sample shall be rinsed the filtering crucible with a few ml. of alcohol and ether, dried for approximately 15 minutes at 95 degrees C. plus or minus 2 de- grees C., cooled in a desiccator and weighed. The loss in weight shall be calculated
20、as the percentage of potassium chlorate. 4.3,4.2 Leud mide. The residue remaining from the potassium chlorate determination shall be extracted with 6 mi. portions of satu- rated ammonium acetate solution at about 25 degrees C. (hot saturated ammonium acetate solution must not be used as it dissolves
21、 anti- mony sulfide to some extent) each portion be- ing agitated for about 30 seconds, until the washings no longer give a yellow precipitate mith a few drops of potassium dichromate solu- tion. The use of more than 60 ml. of ammon- ium acetate solution should be avoided. Tkie residue shall be wash
22、ed with distilled water, rinsed with a few ml. of alcohol and ether, dried for approximately 15 minutes at 109 degrees C, plus or minus 5 degrees C., cooled in a desiccator and weighed. The loss in weight ahall be Calculated as the perwntage of lead azide. 4.3.4.3 Antinumy sulF&e. The residue re- ma
23、ining from the lead azide determination shall be extracted with concentrated hydro- chloric acid until free from antimony sulfide. (This extraction can be made without remov- ing the sample from the filtering crucible and thus running the risk of disturbing the as- bestos mat.) Suction shall be appl
24、ied and most of the antimony sulfide extracted with cool concentrated hydrochloric acid, then rinsed thoroughly with hot concentrated hydrochloric MIL-D-46262A (MU) acid, ignited to separate sulphur and organic matter, cooled in a desiccator and weighed. The loss in weight shall be calculated as the
25、 percentage of antimony sulfide. 4.3.4.4 Carborundum. The original weight of the ignited filtering crucible shall be sub- tracted from the weight of the crucible and residue after the antimony sulfide deterrnina- tion and the difference calculated as the per- centage of carborundum. 4.3.5 Functming.
