27、 9 - In order to provide an adequate weight spread for production purposes the min density for RDX type pellets should be 1.59 and the max 1.69 gm/cc. Small pellets may require a reduction in the OD, length tolerance, and density spread to obtain an acceptable weight tolerance of at least + 1.5 mg.

28、HMX type pellets should have a density spread of 1.65 to 1.75 gm/cc. 10 - A pellet which fails to meet the weight require- ment per note 7 but meets the dimensional re- quirements shall be acceptable provided the dens- ity o the pellet is between (see end item draw- ingis) ) . 11 - Advisory: - The f
