CEI EN 61000-4-4

BILINGUAL

This part of IEC 61000 relates to the immunity of electrical and
electronic equipment to repetitive electrical fast transients. It
gives immunity requirements and test procedures related to
electrical fast transients/bursts. It additionally defines ranges
of test levels and establishes test procedures.

The object of this standard is to establish a common and
reproducible reference in order to evaluate the immunity of
electrical and electronic equipment when subjected to electrical
fast transient/bursts on supply, signal, control and earth ports.
The test method documented in this part of IEC 61000 describes a
consistent method to assess the immunity of an equipment or system
against a defined phenomenon.

NOTE As described in IEC Guide 107, this is a basic EMC
publication for use by product committees of the IEC. As also
stated in Guide 107, the IEC product committees are responsible for
determining whether this immunity test standard is applied or not,
and if applied, they are responsible for determining the
appropriate test levels and performance criteria^.(1)

The standard defines:

• test voltage waveform;

• range of test levels;

• test equipment;

• calibration and verification procedures of test
equipment;

• test setups;

• test procedure.

The standard gives specifications for laboratory and in situ
tests.

⁽¹⁾ TC 77 and its subcommittees are prepared to
co-operate with product committees in the evaluation of the value
of particular immunity tests for their products.
