8.4.2 Component Level Tests.
Appendix D, Annex 2 describes the component level tests required for munitions that have
undergone sequential environmental testing. Component level assessment of energetic and
pressure vessel components is required in order to estimate the probability and severity of failure
during operational use. In addition to warheads and rocket motors, other items may require these
tests. Examples are gas generators, pressure vessels, safe and arming devices, or thermal batteries
which could present a hazard to personnel. Background and rationale for these tests are provided
in Appendix A, Annex 2.
8.5 ADDITIONAL TESTS AND ASSESSMENTS.
Tests and assessments in addition to the environmental and operational testing described above are
required as part of the S3 Package. In particular, Hazard Classification, Insensitive Munitions
Assessment, and Munition Software System Safety Assessment are required but the details
regarding the series of tests are not provided in this document since they are governed by other
standards. References to the governing documents are provided below.
8.5.1 Munition Hazard Classification.
Appropriate munition hazard classification testing shall be conducted in accordance with
Technical Bulletin (TB) 700-2.
8.5.2 Insensitive Munitions (IM) Assessment.
The IM assessment testing shall be conducted in accordance with MIL-STD-2105, STANAG 4439
and AOP-39. For a system expected to have significant changes to its vulnerability with age/use,
using environmentally stressed munitions within IM vulnerability test and assessment should be
considered.
8.5.3 Munition Software System Safety Assessment.
Munition software shall be designed, assessed and tested to assure its safety and suitability for
service in accordance with ITOP 01-1-057 and Quadripartite Advisory Publication (QAP)-268.
8.5.4 Firing Circuits.
Conduct a full hazard assessment using Fault Tree Analysis (FTA), Failure Modes and Criticality
Effects Analysis (FMECA), and sneak circuit analysis techniques and examine the firing system
for adequacy of design and safety features and for compliance with specifications. Use
examinations and simulated firings to determine that firing switches and interlocks are located so
as to protect against accidental firings and that firing circuit connections are protected against
accidental grounding or shorting. Development testing should include tests to ensure the firing
circuit acts as intended and that it will not fire when faults are introduced into the circuit.
