2-1. CHARACTERISTICS OF EXPLOSIVES See table 2—1 for the principal types of U.S. explosives commonly used for military purposes. a. Detonating velocity. See table 2—1. b. Relative effectiveness factor. (1 ) The formulas used in this chapter give the weight of explosive (P) required for a demolition task in pounds of TNT. (2) Where a type of explosive other than TNT is used, the correct weight of explosive is obtained by dividing P by the relative effectiveness factor for the explosive used. See table 2—1, column 4. (3) Example. For a steel cutting charge, P is found to be 21 lbs. of TNT. Composition C—4 is to be used. Therefore, the correct weight of C—4 required is 21 -j- 1.34= 15.7 lbs. of C—4. Use 16 lbs. of C—4. (4) This adjustment is not used for rules of thumb. (5) For Türtliër details see TM 5—25. c. Round/ng-Off Rule.
