(Note) EN 61010-1:2010 specifies the pollution degrees and their 
requirements as follows. The GOM-804/805 falls under degree 2. 
Pollution refers to “addition of  foreign matter, solid, liquid, or 
gaseous (ionized gases), that may produce a reduction of  dielectric 
strength or surface resistivity”. 
  Pollution degree 1: No pollution or only dry, non-conductive pollution 
occurs. The pollution has no influence. 
  Pollution degree 2: Normally only non-conductive pollution occurs. 
Occasionally, however, a temporary conductivity caused by 
condensation must be expected. 
  Pollution degree 3: Conductive pollution occurs, or dry, 
non-conductive pollution occurs which becomes conductive due to 
condensation which is expected. In such conditions, equipment is 
normally protected against exposure to direct sunlight, precipitation, 
and full wind pressure, but neither temperature nor humidity is 
controlled.
