24、63201 (AR) shall be numbered consecutively to facilitate proper testing sequence. From each of the samples above, test samples shall be selected and prepared for laboratory tests described in 4.4.1.2 through 4.4.1.5. 4.4.1.2 Test sample A - Heat of explosion determination.- Eight (8) samples shall b
25、e selected at random from the 25 samples designated. least 20.0 grams shall be reduced in size as described in Method 509.3 of MIL-STD-286 to pass through a U.S. No. 20 mesh screen. Each of the eight resulting samples shall be stored in a separate moisture-tight container, From each of the eight sam
26、ples, a portion weighing at 4.4.1.3 Test sample B - Strand burning rate determination. From each of the sections after removal of specimens for test sample A, as many 1/8 to 3/16 inch wide strands as are needed to obtain one satisfactory strand from each sample shall be cut. One 1/8 to 3/16 inch wid
27、e strand shall be removed from the remaining 17 samples not utilized in 4.4.1.2. The remainder of each of the sections plus unsatisfactory strands (if any) shall be saved for test sample D. The twenty five 1/8 inch wide strands, from all 25 samples thus obtained, shall be further cut to a length as
28、described in Method 803.1 of MIL-STD-286 and the remaining short lengths shall be retained for test sample C. The resulting strands shall be stored in moisture-tight containers and properly identified. 4.4.1.4 Test sample C - MoistuLe determination. Each of the short lengths of 1/8 inch wide strips
29、remaining after the prepar- ation of test sample B shall be cut to a length of 3.0 inches. Then each of these lengths shall be further reduced in size by cutting into approximately 1/8 inch squares. The resulting material (at least 20.0 grams in weight) shall be thoroughly blended, stored in a moist
30、ure-tight container and properly identified. 4.4.1.5 Test sample D - General chemical analysis and Taliani test. From the material remaining after the preparation of test sample B and test sample C, a section weighing about 4.0 grams shall be selected from each of the 25 samples. These sections shal
31、l be reduced in size as described in Method 509.3, MIL-STD-286, and blended thoroughly to give a uniform sample weighing at least 160 grams. 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-P-63201 13 = 7779706 0345i105 2 = MIL-P-63201 (AR) 4.4.
