MIL-STD-2105D

Primary evidence of a Type I reaction is the observation or measurement of a shock wave with the magnitude and timescale of a purposely detonated calibration test or calculated value, and the rapid plastic deformation of the metal casing contacting the energetic material with extensive high shear rate fragmentation.

Secondary evidence may include the perforation, fragmentation and/or plastic deformation of a witness plate and ground craters of a size corresponding to the amount of energetic material in the munition.

b.  Type II (Partial detonation reaction).  The

second most violent type of munition reaction where some of the energetic material is consumed in a supersonic decomposition.

Primary evidence of a Type II reaction is the observation or measurement of a shock wave with magnitude less than that of a purposely detonated calibration test or

calculated value and the rapid plastic deformation of some, but not all, of the metal casing contacting the energetic material with extensive high shear rate fragmentation.

Secondary evidence may include scattered burned or unburned energetic material; the perforation, fragmentation, and/or plastic deformation of a witness plate; and ground craters.

c.  Type III (Explosion reaction).  The third most violent type of munition reaction with sub-sonic decomposition of energetic material and extensive fragmentation.

Primary evidence of a Type III reaction is the rapid combustion of some or all of the energetic material once the munition reaction starts and the extensive fracture of metal

casings with no evidence of high shear deformation resulting in larger and fewer fragments than observed from purposely detonated calibration tests.

Secondary evidence may include significant long-distance scattering of burning or unburned energetic material; witness plate damage; the observation or measurement of overpressure throughout the test arena with a peak magnitude significantly less than and significantly longer duration than that of a purposely detonated calibration test; and ground craters.
