Safety
The high voltage interference pulse can contain a very large quantity of energy and every precaution shall be taken to
avoid contact with EUT during a test. It is highly recommended that at least one other person is present (or very close
by) during the test.
Test Configuration
EUT Operating Configuration
All operating configurations should be tested with appropriate performance criteria defined for each test.
Performance Criteria
From BS EN 61000-4-5 : 2006
Performance criteria C: Temporary loss of function or degradation of performance, the correction of which requires
operator intervention.
