6、 the following: “4.4.1 Propellant testing. 4.4.1.1 Sampling. Each lot of propellant submitted for acceptance shall be sampled by the contractor under the direction of the Government inspector. Twenty five individual even-speed-rolled sheets shall be selected at random for each inspection lot (see 6.
7、3). A sample at least 11 inches long by 4 inches wide shall be cut at random from each of the 25 sheets selected. The long axis of each sample shall be in a direction which is parallel to the direction of final rolling. The samples shall be numbered consecutively to above, test samples shall be sele
8、cted and prepared as described in 4.4.1.2 through 4.4.1.5 and Figure 1. ,facilitate proper testing sequence. From each of the samples 4.4.1.2 Test Sample A. Heat of explosion determination. Eight (8) samples shall be selected at random from the 25 samples designated. From each of the eight samples,
9、a portion weighing at 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. 4.4.1.3 Test Sample B. Strand burning rate determination.
10、 To obtain a total of 60 acceptable strands, two acceptable strands shall be removed from 15 of the original 25 samples and three acceptable strands shall be removed from the remaining 10 samples. The strands shall be of the width prescribed in Method 803.1 of MIL-STD-286. Since the strands will be
11、too long, they shall be cut to the correct length range. The residual short lengths shall be used for Test Sample C. The long strands for Sample B shall be stored in moisture tight containers and properly identified. 2 Licensed by Information Handling Servicesi MIL-P-63201 (AR) AMENDMENT 1 4.4.1.4 T
12、est Sample C. Moisture determination. 25 moisture samples representing each of the 25 original samples shall be selected from the residual short lengths from the preparation of Sample B. The selected moisture samples shall be cut to a length of approximately 3.0 inches. These 3.0 inch samples shall
13、be diced into 1/8 inch squares. resultant squares shall be thoroughly blended together , stored in a moisture-tight container and properly identified. At least 20 grams of propellant will be required. All 4.4.1.5 Test Sample D. General chemical analysis and taliani test. From the material remaining
14、after the preparation of samples A, B and C a section weighing at least 4.0 grams shall be selected from each of the original 25 samples. in Method 509.3, MIL-STD-286 and blended thoroughly to give a uniform sample weighing at least 160 grams. The sample shall be stored in a moisture-tight container
15、 and properly identified .I These sections shall be reduced in size as described PAGE 6 4.5.1: Delete the first sentence and substitute the following: “TO determine conformance of the propellant with 3.2, 3.4, 3.5 and 3.6 the following analysis shall be carried out on the samples taken in 4.4.1.2, 4
