EN50082-1 Electromagnetic compatibility - Generic immunity standard

Definitions:          
  Port: Particular interface of the specified apparatus with the external  
    electromagnetic environment.    
             
  Enclosure port: The physical boundary of the apparatus which electromagnetic fields may
    radiate through or impinge on.    
             
  Cable port: A point at which a conductor or cable is connected to the apparatus.
    Example are signal,control and power ports.  
             
  Public mains Electricity lines to which all categories of consumers have access and
  network: which are operated by supply or distribution undertaking for the purpose
    of supplying electrical energy.    
             
  Functional A point on the apparatus which is connected to earth for the purposes
  earth port: other than electrical safety.      
             
             
 
Performance criteria:          
  A: The apparatus shall continue to operate as intended. 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 then either of
    these may be derived from the product description and documentation
    and what the user may reasonable expect from the apparatus if used as
    intended.        
             
  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 of the  
    permissible performance loss is not specified by the manufacturer then
    either of these may be derived from the product description and  
    documentation and what the user may reasonable expect from the
    apparatus if used as intended.    
             
  C: Temporary loss of function is allowed, provided the function is self  
    recoverable or can be restored by the operation of controls.

  Amplitude modulated 80 %AM (1kHz)   the unmodulated

    +/-8 Air kV (charge   contact and/or air  
    discharge voltage)   discharge test B
NOTE 1. Applicable only to apparatus containing devices susceptible to magnetic fields, such as Hall
  elements, electrodynamic microphones, magnetic field sensors, etc.  
NOTE 2. For CRTs the acceptable jitter depends upon the character size and is computed for a test
   level of 1A/m as follows:        
  Jitter (mm) = [3 x character size (mm) + 1]/40      
  As jitter is linearly proportional to the magnetic field strength tests can be carried out at other
  test levels extrapolating the maximum jitter level appropriately.
