If in the combined first and second sample a total of 4 or more defectives are found, the lot shall be rejected. The tes
9、t shall be performed as specified in 4.3.3.1 using test equipment as specified in 4.2.4. 4 :2.3.3.2 aspirated with suction and the bottom of the crucible wiped dry, using tissue paper. The washing shall be continued, using one more 3.0 ml. portion, two 2.0 ml. and two 1.0 nil. portions, making a tot
10、al of 12.0 ml. The crucible shall be removed and the bottom of the crucible. the funnel, the adapter and the suction flask washed with water. The test tube shall be placed in the flask and the stem of the filter- ing funnel inserted into the test tube. The crucible and contents shall be washed with
11、one 1.0 ml. portion of Solution Number 1 as above, and aspirated with suction, catching the filtrate in the test tube, The test tube shall be removed, 1.0 ml. of distilled water added and the chlorzte ion, determined as follows. The tube shall be inclined at an angle of about 4.5 degrees ana from a
12、dropper about 0.0 ml. of a solution containkg 1.0 gm. of diphenylamine in 100 gm. cf concentrated salfuric acid shall be run down the side of the tube, so that there will )e two distinct layers. If an appreciable amomt of chlorate ion is present, a distinct b1i:e ring will be visible at the border o
13、f the two layers. On shaking the tube, the ring disappears, but the coiiteiits assume a blue coloiation, which lasts several seconds, depending on the amount of chlorate ion present. If only a trace of chlorate ion is present the blue ring may not form, but upon shaking the test tube, a slight bluis
14、h coloration will appear momentarily throughout the solution, lasting only a fraction of a second. If a definite blue ring forms, the washing shall be repeated as before using one 1.0 ml. portion of Solution Number 1, and finally a 0.5 ml. portion of the same soiution, as needed, depending on the ou
15、tcome of the tests for the chlorate ion. (Usually a Wal of 14.0 or 14.6 ml. of Solu- tion Xumber 1 is sufficient.) After complete removal of potassium chlorate the inside of the crucible shall be washed with 1.0 ml. of Solution Number 2 and aspirated immedia- tely. The bottom of the crucible shalt h
16、e wiped dry with tissue paper and dried in an oven at 80 degrees C. plus or minus 1 degree C. for 30 minutes, cooled in a desiccator and weighed.

The bottle shall be stoppered and shaken vigorously for several minutes and then allowed to stand overnigh. Portions of the saturated so

A portion of approx- imately 1 gm. of the sample shall be accur- ately weighed directly into a tared 30 ml. sin- tered glass crucible of medium porosity. Five ml. of one percent nitric acid shall be added and the crucible constantly swir
20、led for one minute in order to dissolve all the ingredients of the powder except antimony sulfide. Care shall be taken not to spill any liquid. The mixture shall be filtered by applying suction employing a vacuum flask, The crucible shall be removed from the adapter and the bottom wiped dry with tis
21、sue paper, The operations of washing, using 5.0 ml. of one percent nitric acid each time and swirling for exactly one minute shall be repeated. After a total of 40 ml, of one percent nitric acid has been used, the crucible shall be removed and the bottom of it washed with water. The funnel, the funn
22、el adapter and the vacuum flask shall be washed with water; the filtrate and washings shall be discarded. About 1 ml. of a saturated solution of ferric ammonium sul- fate shall be placed in the flask. The contents of the crucible shall be treated as before with 0.0 ml. of one percent nitric acid and
23、 filtered by means of suction into the flask. If the liquid in the flask turns red, due to the pre- sence of the thiocyanate ion in the filtrate, the washing of the contents in the crucible shall be repeated with additional 5.0 ml. por- tions of one percent nitric acid until a nega- tive test for th
24、e sulfocyanate ion is affected. (Usually a total of 50 ml. is sufficient.) The crucible and contents shall be rinsed with alcohol and then with ether, and then aspir- ated until the odor of ether is no longer de- tectable. The crucible and contents shall be dried in an oven at 80 degrees C. plus or
25、minus 1 degree C. for 30 minutes, cooled in . a desiccator and weighed. The percentage of antimony sulfide shall be calculated as fol- lows : Antimony sulfide, percent -1 100A B where : A .= weight of residue in the crucible. B = weight of sample on a moisture- free basis. 4.3.2.2.3 Lead azide. The
26、lead azide con- tent shall be determined using the (Eudio- meter) method and apparatus in MIGSTD- 650 Method No. 407.1. 4.3.2.2.4 Lend tltiocyairate. The percentage of lead thiocyanate in the sample shall be calculated on a moisture-free basis by sub- tracting from 100 the sum of the percentages of
27、potassium chlorate, antimony sulfide and lead azide. 4.3.3 Functioning. 4.3.3.1 Sewitivity. The primer shall be assembled to the applicable test fixture spec- ified in 4.2.4 so that he firing pin will strike the sensitive end of the primer. A steel ball “i,; inch in diameter and weighing 3.95 ounces
