initiation shall not lead to functioning of the AHMD. The interrupter shall adhere to the
following requirements:
(1) Interrupter lock. An interrupter(s) shall be directly locked or restrained
mechanically in the interrupted position by at least one safety feature. The safety feature shall be
removed only when an IM thermal threat environment is sensed.
(2) Interruption position. If safety is dependent upon the presence of an interrupter,
the design shall prohibit assembly in an unsafe state. A single interrupter is acceptable if the
omission of the interrupter will prohibit explosive train transfer.
(3) Interruption effectiveness.
The effectiveness of the interrupter shall be
numerically determined in accordance with the Primary Explosive Component Safety Test of
MIL-STD-331 or by similar methodologies.
j.
Qualified energetic materials.
(1) Explosive materials listed in Table 1 of MIL-STD-1316 and explosive and
pyrotechnic materials listed in Tables 1 and 2 of MIL-STD-1901 are approved by all services for
use in a position leading to the initiation of a warhead or the ignition of a rocket or missile motor
without interruption. These materials are also acceptable for use without interruption in the
AHMD.
(2) The energetic material used in the AHMD shall not be altered by any means
(precipitation, recrystalization, grinding, density changes, addition of materials, etc.) likely to
increase its sensitivity beyond that at which the material was qualified, and at which it is
customarily used, unless it is requalified.
(3) Subject to review and concurrence by the appropriate SSRA, energetic materials
which do not appear in the above referenced tables may be utilized physically in-line in an
AHMD if the material has been qualified and meets the U.S. Annex of AOP-7, Paragraph
10.7.16.4.1.1.b, Requirements for Booster Explosives.
k. The qualification test and analysis efforts to be conducted for the AHMD shall receive
concurrence from the appropriate SSRA. JOTP-052 shall be used as a guide for appropriate test
selection and quantities to be tested. In addition, testing of the AHMD shall include functioning
in IM thermal threat environments to determine the minimum and maximum reaction time to
assess the potential hazards to firefighters and other first responders.
l. All components used in the AHMD system shall be selected to be compatible and
stable so that under all specified natural and induced environmental conditions in its life cycle,
none of the following shall occur in the AHMD system prior to exposure to a thermal threat:
(1) Arming or functioning.
(2) Dangerous ejection or exudation of material.
