Electromagnetic Compatibility Verification
Verification in Accordance with EC Council Legislation Directive
2004/108/EC and 2014/30/EU
Compatibility in Accordance with EN 61326-1 and NAMUR NE 21
Recommendation
The electromagnetic compatibility (EMC) requirements, applicable for electrical equipment for
measurement, control, and laboratory use in general are anchored in the international standard
EN 61326. 3 different performance criteria are distinguished in this standard:
A class
A
device operates as intended during the test. This device can withstand the immunity
tests without any noticeable performance degradations within the specification limits of the
manufacturer.
A class
B
device operates as intended after the test. The device shows temporary degradation
or loss of function of performance during the test but self-recovers from that state when the
exposures are ceased.
A class
C
device has loss of function. The device may need manual restoration. During the test
a temporary loss of function is allowed, as long as an operator can restore the device back to
operation.
The requirements of the association for standard and control and regulations of the German
chemical industries, defined in the NE 21 recommendation, are partly higher compared to the
test levels and failure criteria defined in EN 61326-1. For the product qualification, the failure
criteria and test levels selected always represent the worst case conditions.
EN 61000-4, as a generic standard, defines the test setups for the specific required test for
EN 61326-1 and NE 21.
