Electromagnetic compatibility (EMC) – Part 6-2: Generic standards – Immunity for industrial environments
|Publication Date:||1 January 2005|
|ICS Code (Immunity):||33.100.20|
This part of IEC 61000 for EMC immunity requirements applies to electrical and electronic apparatus intended for use in industrial environments, as described below. 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.
This generic EMC immunity standard is applicable if no relevant dedicated product or product-family EMC immunity standard exists.
This standard applies to apparatus 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. This standard applies also to apparatus which is battery operated and intended to be used in industrial locations.
The environments encompassed by this standard are industrial, both indoor and outdoor.
Industrial locations are in addition characterised by the existence of one or more of the following:
- industrial, scientific and medical (ISM) apparatus (as defined in CISPR 11);
- 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. These test requirements represent essential electromagnetic compatibility immunity requirements.
NOTE 1 Information on other disturbance phenomena is given in IEC 61000-4-1.
Test requirements are specified for each port considered.
NOTE 2 Safety considerations are not covered by this standard.
NOTE 3 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 4 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.
