APPENDIX A. BACKGROUND/RATIONALE
ANNEX 1. ENVIRONMENTAL TESTS
A.1-2.10 Cargo Aircraft Decompression (Appendix C, Annex 1, Paragraph C.1-12).
Rapid decompression can result when cabin pressurisation is lost during an accident scenario in a
transport aircraft. Rapid decompression may result in damage to munition seals during cargo
aircraft transportation. This test should be conducted using packaged munitions to verify that the
packaging does not present a secondary hazard to the munition or aircraft crew. An initial cargo
compartment pressurisation of 60 kPa is sufficient to address most common military transport
aircraft worldwide.
A.1-2.11 Mould Growth (Fungus and Biological Hazards) (Appendix C, Annex 1, Paragraph C.1-
13).
Microbial deterioration is a function of temperature and humidity and is an inseparable condition
of hot-humid tropics and the mid-latitudes. MIL-STD-810, Method 508 is used to determine if
mould growth will occur and, if so, how it may degrade/impact the use of the munition. Twenty-
eight days is the minimum test period to allow for mould germination, breakdown of carbon-
containing molecules, and degradation of material. This is a non-sequential test and may be
conducted on leftover components or material samples.
A.1-2.12 Contamination by Fluids (Appendix C, Annex 1, Paragraph C.1-14).
Contamination of the munition may arise from exposure to fuels, hydraulic fluids, lubricating oils,
solvents and cleaning fluids, de-icing and anti-freeze fluids, insecticides, sunblock, disinfectants,
coolant dielectric fluid, and fire extinguishants. Select the fluids most commonly encountered
throughout the munitions life cycle and apply to the item in the most severe deployment
configuration as determined by the LCEP. Use the intermittent exposure method described in
MIL-STD-810, Method 504. Contamination effects must be analyzed for its immediate or
potential (long term) effects on the proper functioning or safety of the munition.
A.1-3 MECHANICAL ENVIRONMENT TESTS (APPENDIX C, ANNEX 2).
Provided below are the rationale for the dynamic environments likely to result from normal usage
in severe environmental conditions, or from plausible mishandling during logistic and field
operations. The weapons should be tested following temperature conditioning at either the SRE
temperature (packaged or unpackaged as appropriate for the test configuration) for the hot weapons
and -46 °C for the cold weapons (rationale given at Annex 1, paragraphs A.1-1.3 and A.1-1.5).
For naval launched munitions, temperature conditioning using the M3 and A1 cycles may be
applicable when the storage conditions are not well defined by the LCEP. Operational temperature
conditions for submarine munitions are more controlled within a limited range.
