Thank you Dave, for your explanation.
Since there is a proposal to add Class F limits specifically for
Information Technology Equipment by the IEC Technical Committee 74,
how does that affect the sweeping scope of the current EN61000-3-2
standard that states that it now applies to products NOT covered by the
previous standard EN60555-2, thereby including ITE. If the limits for ITE
equipment, as proposed by IEC, are changing, it hardly makes sense to
agitate manufacturers to redesign product, and then redesign it again to
meet requirements.
To whom can we complain that this jerking around on the part of CENELEC
is not conducive for harmonized trade in Europe! (Not that they would
listen.)

Pat:
Class E limits would be for equipment greater than 1000 watts. Class E
limits are contained in IEC document SC77A/164/CD. It has been commented on
by national committees and the results will be discussed at the next WG1
meeting starting on 24 April 1997.
A previous draft from SC77A/WG1 contained a definition for professional
equipment for the first time. It is repeated in the above committee
document. The definition is "equipment for use in trades, professions, or
industries and which is not intended for sale to the general public. The
application shall be specified by the manufacturer." This definition was
modified by the last sentence because of the TC74/WG9 negotiations with
SC77A.
As additional information, TC74 will make a presentation at that meeting for
limits specific for Information technology equipment. We are proposing a
Class F. The limits proposed are contained in TC74/436/CDV.
If you need additional questions you can call me on 610 648 3653.

Convenor TC74/WG9
