(see 6.6) This test measures the force required for a cone point to penetrate the M112 demolition charge for a specified distance. The samples shall be selected after the charges have been packaged in c
46、harge containers. Any charge that breaks or physically separates during the sample preparation will not be replaced. The breakage or separation shall be a nonconforming unit and result in lot rejection. External temperature of the charges at time of test shall be 73 +/- 3 degrees F (22.8 +/- 1.7 deg
47、rees C). Samples shall be temperature conditioned for a minimum of 24 hours prior to removing from the charge container. Each sample demolition charge shall be removed from its charge container and two penetrameter readings shall be taken on each M112 charge at approximately one inch from each end of the sample charge. The maximum of the two penetrameter readings shall be recorded unless one reading is less than 2.0 pounds or more than 8.0 pounds. If one reading is below 2.0 or greater than 8.0, that reading w
