Note 1: This chart is intended to aid in the determination of the IM reaction for munitions that produce projections. It is not intended for bare explosive charges (i.e. demolition charges) since they may detonate or explode without producing fragments with energy greater than 20J. The measurement of overpressure should always be taken into account along with other test instrumentation data to determine the proper reaction type.
FIGURE 1. Relationship of projection kinetic energy and hazard division (20 J).
f. Type VI (No reaction). The least violent type of munition response where any reaction is self-extinguished immediately upon removal of the external stimulus.
Primary evidence of a Type VI reaction is no reaction of the energetic material without a continued external stimulus;
the recovery of all or most of the energetic material with no indication of sustained combustion; and no fragmentation of the casing or packaging greater than from a comparable inert test item.
Secondary evidence - none.
3.12 Service review organization. The various organizations within the services which are responsible for the assessment of weapon safety or IM characteristics (see paragraph
6.6). Note: Referred in NATO STANAGs as National S3 Authority.
