Outlines of Major Noise Regulation Standards
Continued from the preceding page.
(2)Scope of CISPR 22 Regulation
This regulation applies to information technology
equipment (ITE) which are defined as:
(a) Equipment that receives data from external signal
sources;
(b) Equipment that processes received data;
(c) Equipment that outputs data
(d) Equipment that has less than 600V rated voltage in
power supply
4. Limits of VCCI Voluntary Regulation
(1)VCCI recommend measurement at 10m distance. 3m or
30m distance measurement are also allowed.
(2)Scope of VCCI Voluntary Regulation
This regulation applies to information technology
equipment (same as CISPR Pub.22), but the application
is excluded on the following equipment:
· Equipment for which other regulations already exist
(e.g., household electrical appliances, radio and TV
receivers)
· In station equipment principal purpose of which is
electrical communication
· Industrial plant control system for which information
processing is a secondary system function
· Industrial, commercial and medical testing and
measuring systems for which data processing is a
secondary system function
· Information equipment for which CISPR is conducting
further deliberation
VCCI is the acronym of Voluntary Control Council for
Interference by Data Processing Equipment and
Electronic Office Machines.
VCCI is organized by the following organizations:
· Japan Electronics and Information Technology
Industries Association (JEITA)
· Japan Business Machine and Information System
Industries Association (JBMIA)
· Communication and Information network Association of
Japan (CIAJ)
