APPENDIX A. BACKGROUND/RATIONALE
ANNEX 3. NON-SEQUENTIAL SAFETY TESTS
A.3-1 ELECTROMAGNETIC ENVIRONMENTAL EFFECTS (E3) ASSESSMENT AND
TESTING (APPENDIX H, ANNEX 1).
The following E3 effects should be considered to assess the safety of the weapon when exposed to
the environment which may be encountered during the weapon system stockpile to safe separation
sequence (transportation/storage, assembly/disassembly, staged, loading/unloading, platform-
loaded, and immediate post-launch). Levels should encompass sea, land, and aviation storage,
usage, maintenance, and shipment requirements as identified in the LCEP.
A.3-1.1 HERO (Appendix H, Annex 1, Paragraph H.1-1).
This test assesses the safety of the weapon at a system level by exposing the weapon and its
associated platform(s) to its operational electromagnetic environments and monitors the response
of the weapons Electrically Initiated Devices (EIDs also known as Electro-explosive Devices
(EEDs)) or Electronic Safe and Arming Devices (ESADs) and associated firing circuits when
exposed.
A.3-1.2 ESD (Appendix H, Annex 1, Paragraph H.1-2).
These tests assess the safety of the weapon when exposed to ESD phenomenon such as those
encountered during handling and helicopter transport. Test asset quantities should be based on
MIL-STD-331.
A.3-1.3 Lightning Hazard (Appendix H, Annex 1, Paragraph H.1-3).
These tests assess the safety of the weapon when exposed to near and direct strike lightning, which
may occur during logistic and field operations.
A.3-1.4 Electromagnetic Compatibility (Appendix H, Annex 1, Paragraph H.1-4).
Electromagnetic Compatibility (EMC) tests assess the suitability of the weapon to operate within
the electromagnetic environment for which they are designed to be used. These tests are performed
on a powered weapon during simulated normal operation and are designed to assess to what extent
the weapon not only is affected by the electromagnetic environment in which it is expected to
operate but also its electromagnetic effect on other electrical systems it interacts with or is in close
proximity to (e.g., on the same platform). Much of this testing is for reliability purposes however
some EMC tests provide safety assurance, for example those designed to monitor for interference
carried into the weapon via physical electrical interfaces which may affect the performance of EID
and/or ESAD firing circuits.
