Electromagnetic compatibility - Generic immunity standard
Description of locations
The environments encompassed by EN 61000-6-1 are residential, commercial and light-industrial locations, both
indoor and outdoor. The following list, although not comprehensive, gives an indication of
locations which are included:
 | residential properties, e.g. houses, apartments; |
| retail outlets, e.g. shops, supermarkets; |
| business premises, e.g. offices, banks; |
| areas of public entertainment, e.g. cinemas, public bars, dance halls; |
| outdoor locations, e.g. petrol stations, car parks, amusement and sports centers; |
| light-industrial locations, e.g. workshops, laboratories, service centers. |
Locations which are characterized by being supplied directly at low voltage from the
public mains network are considered to be residential, commercial or light industrial.
The environments encompassed by EN 61000-6-2 are industrial
locations, 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 which are characterized by the existence of one or more of the following
conditions:
| 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) apparatus; |
| heavy inductive or capacitive loads are frequently switched; |
| currents and associated magnetic fields are high. |
Determination of pass/fail criterion
The variety and the diversity of the apparatus within the scope of these
standards makes it difficult to define precise criteria for the evaluation of
the immunity test results
If, as a result of the application of tests, the apparatus (EUT) becomes dangerous or
unsafe, the apparatus shall be deemed to have failed the test.
For the evaluation of the effects of the immunity tests, the following mentioned
immunity criteria are followed:
| Performance Criterion A: The apparatus shall continue to operate as intended
during and after the test. No
degradation of performance or loss of function is allowed below a performance level
specified by the manufacturer, when the apparatus is used as intended. The performance
level may be replaced by a permissible loss of performance. If the minimum performance
level or the permissible performance loss is not specified by the manufacturer, either
of these may be derived from the product description and documentation, and
from what the user
may reasonably expect from the apparatus if used as intended. |
| Performance Criterion B: The apparatus shall continue to operate as intended
after the test. No degradation of performance or loss of function is allowed below a
performance level specified by the manufacturer, when the apparatus is used as intended.
The performance level may be replaced by a permissible loss of performance. During the
test, degradation of performance is however allowed. No change of actual operating state
or stored data is allowed. If the minimum performance level or the permissible performance
loss is not specified by the manufacturer, either of these may be derived from the
product description and documentation, and from what the user may reasonably expect from the
apparatus if used as intended. |
| Performance Criterion C: Temporary loss of function is allowed, provided the
function is self recoverable or can be restored by the operation of the controls. |
