Twenty fuzes shall be selected from each lot for tests as speci- fied in 4.5. Sampling of component materials is prescribed in parag
10、raphs covering tests of the component material. 4.3 InspectioniInspection shall be as specified in Specification MIGG-2550. 4.4 Determination of binder-lubricant con- tent of tetryl booster charge.-The binder- lubricant content of the tetryl to be used in the booster charge shall be determined on ea
11、ch lot or sublot at the time of loading. Ap- proximately 8 ounces shall be selected by the inspector. The binder-lubricant content shall be analyzed as follows: 4.4.1 Procedure.-Transfkr a weighed por- tion of approximately 5 grams (gms.) of the sample selected as indicated above to a tared filterin
12、g crucible and extract with four 10- milliliter (mi.) portions of acetone, maintain- ing each portion in contact with the residue for approximately 5 minutes befre applying suction, breaking up any lumps which may persist and washing down the sides of the crucible with each 10-ml. portion of acetone
13、 to insure complete removal of the tetryl. Aspirate the residue until the odor of ace- tone is no longer detectable and dryat 100“ to 105“ C. for one hour. Calculate the weight of residue as percentage of binder-lubricant in the sample. 4.4.2 Retest,-If the analysis indicates that the binder-lubrica
14、nt content exceeds the per- centage prescribed on the drawing by not * more than 0.25, the lot r sublot of tetryl may be reblended and resubmitted for test. If in theretest the analysis indicates that the binder-lubricant content still exceeds the per- centage prescribed on the drawing or if in the
15、original test the binder-lubricant con tent of the sample was found to exceed the per- 2 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-AMMUNITION DATA CARD MLF-10734A .
