Appendix F. ESD Testing
The CRVW3 has been subjected to the Class Level 4 of two tests that are based
upon the criteria of standards set by the International Electrotechnical
Commission. The CRVW3 was able to maintain its full functionality after
being subjected to these tests. The tests are known as the Electrical fast
transient/burst immunity test (IEC 61000-4-4) and the Surge immunity test
(IEC61000-4-5).
The Electrical fast transient/burst immunity test is intended to demonstrate the
immunity of electrical and electronic equipment when subjected to types of
transient disturbances such as those originating from switching transients. At
the Class Level 4, the power and earth ports of the CRVW3 are subjected to
4000 volt bursts and the signal and control ports are subjected to 2000 volt
bursts.
The object of the Surge immunity test is to evaluate the immunity of electrical
and electronic equipment to unidirectional surges caused by over-voltages from
switching and lightning transients. At the Class Level 4 of the test, the CRVW3
is subjected to line-to-line open circuit test voltages up to 2000 volts and line-
to-ground open circuit test voltages up to 4000 volts.
Please note that these tests are not intended to test the capability of the
CRVW3 or any other electronic devices to withstand primary lightning strikes.
