1.
SCOPE.
This is a laboratory test which sets forth a set of electrical stress tests for use in the evaluation of
fuzes, electronic safe-arm devices (ESAD), ignition safety devices (ISD), arm fire devices (AFD),
hand-emplaced ordnance (HEO) and their components. The goal of performing these tests is to
highlight any unexpected reaction of the electronics used in safety related devices when exposed
to various credible stressing electrical stimuli and to determine a level of electrical ruggedness of
the safety system.

DESCRIPTION.
3.1
General.
a. This test evaluates the effect of various stressing electrical stimuli on applicable
electronics. In an operating environment applicable devices may be subjected to irregular power
sources and component failures that result in voltage spikes, varying rise times, and other faults
that could degrade the safety system.
b. The test plan (see paragraph 3.5.1) will specify the test, levels and pass/fail criteria.
Tests described herein whose intent is satisfied by system requirements and design validation
testing may be met provided sufficient documentation is submitted to show that the intent of the
requirement has been satisfied. Detailed test requirements may vary by system, and therefore
submission of the test plan to the relevant System Safety Authority (SSA) is required to obtain
concurrence. Table 1 provides the electrical stress test matrix.
