To determine the control measures needed for each sensitivity class, an ESD
requirements matrix was developed. The matrix is separated into two categories: 1)
research and development applications (non-space-flight), Table 2, and 2) space
flight/potential space flight applications, Table 3.
The research and development matrix shows the minimum requirements needed for parts
or assemblies being tested for research or self-training. The space flight/potential space
flight matrix, however, requires more stringent requirements to ensure that flight parts are
kept safe from accidental discharges while being stored, handled, and packaged.
Replacement of damaged flight parts usually costs 10 times more than their equivalent
commercial parts. Also, with the increased use of commercial off-the-shelf (COTS) parts
for space flight applications, extra requirements are needed to ensure that these parts are
not damaged or destroyed while being inspected or assembled.

The purpose of this Electrostatic Discharge (ESD) Control Plan is to provide awareness
and guidance for establishing, implementing, monitoring, and maintaining a work area
that will reduce the probability of ESD damage to flight hardware. The scope of this
control plan is intended to focus on four areas within EED in which ESD can be
detrimental to flight hardware:
1. Design and development.
2. Parts (testing, handling, shipping, packaging, and receiving).
4. Integration/testing (I/T).
