Electromagnetic Compatibility (EMC) - Part 6-2: Generic Standards - Immunity for Industrial Environments
|Publication Date:||23 October 2001|
|ICS Code (Immunity):||33.100.20|
Scope and object
This part of IEC 61000 for EMC immunity requirements applies to electrical and electronic apparatus intended for use in industrial environments, as described below, for which no dedicated product or product-family immunity standard exists.
Immunity requirements in the frequency range 0 Hz to 400 GHz are covered. No tests need to be performed at frequencies where no requirements are specified.
Where a relevant dedicated product or product-family EMC immunity standard exists, it will take precedence over all aspects of this generic standard.
The environments encompassed by this standard are industrial, both indoor and outdoor. Apparatus covered by this standard is intended to be connected to a power network supplied from a high or medium voltage transformer dedicated to the supply of an installation feeding manufacturing or similar plant, and intended to operate in or in proximity to industrial locations, as described below.
Apparatus intended to be used in industrial locations are characterized by the existence of one or more of the following:
- a power network exists powered by a high or medium voltage power transformer dedicated for the supply of an installation feeding manufacturing or similar plant;
- industrial, scientific and medical (ISM)1) apparatus;
- heavy inductive or capacitive loads are frequently switched;
- currents and associated magnetic fields are high.
The object of this standard is to define immunity test requirements for apparatus defined in the scope in relation to continuous and transient, conducted and radiated disturbances, including electrostatic discharges.
The immunity requirements have been selected to ensure an adequate level of immunity for apparatus at industrial locations. The levels do not, however, cover extreme cases, which may occur at any location, but with an extremely low probability of occurrence. Not all disturbance phenomena have been included for testing purposes in this standard, but only those considered as relevant for the equipment covered by this standard.
Test requirements are specified for each port considered.
NOTE 1 - Safety considerations are not covered by this standard.
NOTE 2 - In special cases, situations will arise where the level of disturbances may exceed the levels specified in this standard e.g. where an apparatus is installed in proximity to ISM equipment as defined in CISPR 11 or where a hand-held transmitter is used in close proximity to an apparatus. In these instances, special mitigation measures may have to be employed.
NOTE 3 - The industrial environment may be changed by special mitigation measures. Where such measures can be shown to produce an electromagnetic environment equivalent to the residential, commercial or light-industrial environment then the generic standard for this environment, or the relevant product standard, should be applied.
