PFMF

Version : 21.03.03 , based on 61000-4-8:1993 /A2:2000

EMC-Partner Generator : TRA2000

1. General

Testing take place in climatic specification as follows:
Ambient temperature :               15°C to 35°C
Relative Humidity :                     25% to 75%
Atmospheric Pressure :              86kPa (860 mbar) to 106kPa (1060 mbar)
Other values may be specified in the test specification.

A ground reference plane (GRP) is required and is tied to building Protective Earth (PE).
The EUT shall be conected to a grounding system, representative of good installation practice.
Positioning of power and signal cables shall be representative of good installation practice.
