Thank you Sir. Just the kind of response I was looking for. Much
appreciated.

I would imagine you would want to test the Human Body model, except
exchange the word "fingertip" with "brush":
7.1.1. Human Body Model Sensitivity:
A source of ESD damage is the charged human body, as modeled by HBM
standards. This testing
model represents the discharge from the fingertip of a standing individual
delivered to the conductive
leads of the device. It is modeled by a 100 pF capacitor discharged
through a switching component and
1,500 ohm series resistor into the device under test. The discharge itself
is a double exponential
waveform with a rise time of 2-10 nanoseconds and a pulse duration of
approximately 150 nanoseconds.
The use of a 1,500 ohm series resistor means this model approximates a
current source. All devices
should be considered as HBM sensitive. The HBM ESD sensitivity of devices
may be determined by
testing the device using one of the referenced test methods. HBM
sensitivities can be found in RAC
VZAP, Qualified Manufacturers, List of Products (QML-19500) or Qualified
Manufacturer List (QML-
38535).
Then go to the test references in Table 2:
Table 2 - ESD Susceptibility Test References for Devices
ESD
MODEL
ESD Standards and Methods for Susceptibility Testing of
Devices
HBM ESD STM5.1
MIL-STD-883 Method 3015
MIL-STD-750 Method 1020
MIL-PRF-19500
MIL-PRF-38535
MM ESD-STM5.2
CDM ESD DS5.3.1
To summarize; consider the brush to be part of the operator, and test
accordingly.

Just curious, are you testing the brush dry or dipped in coating?

Subject: [TN] Which ESD Standard
Good morning all,
If I was going to test how much static charge I generated while holding
various kinds of paintbrush for conformal coating, what EOS/ESD
Association standard method should I use?
