The solution shall be swirled for exactly one minute, tak- ing care not to spill any liquid; aspirated with suction and the bottom of the crucible wiped dry, using tissu
31、e paper. The washing shall be continued, using one more 3.0 ml. portion, two 2.0 ml, and two 1.0 ml. portions, making a total 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 th
32、e flask and the stem of the filter- ing funnel inserted into the test tube. The crucible and contents shall be washed with 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

On shaking the tube, the ring disappears, but the contents assume a blue coloration, which lasts several
34、seconds, depending on the I 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 bluish coloration will appear momentarily throughout the solution, lasting only a fraction of a second. If a definite blue ring
35、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 solution, as needed, depending on the outcome of the tests for the chlorate ion. (Usually a total of 14.0 or 14.5 ml. of Solu- tion number 1 is sufficient). After
36、complete removal of potassium chlorate the inside of the crucible shall be washed with 1.0 mi. of Solution number 2 and aspirated immediate- ly. .The bottom of the cruci,ble shall be 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 steel ball ls/is inch in diameter and weighing 3.95 ounces maximum, shall be dropped on the firing pin to function the detonator, from a height of 3 inches, maximum. The height of drop shall be measured as the height from the top of the firing pin to the bottom of the ball. A detonator that fails to fire or fails to create a hole in the lead disc of the required size shall be classed defective. 4.3.
