(1) VCCI recommends measurement at 10m distance;
(2) Scope of VCCI Voluntary Regulation

Outlines of Major Noise Regulation Standards
Continued from the preceding page.
This regulation applies to information technology
equipment (ITE) which are defined as:
(a) Equipment that receives data from external signal
(b) Equipment that processes received data;
(c) Equipment that outputs data; and
(d) Equipment that has less than 600V rated voltage in
3m or 30m distance measurements are also allowed.
This regulation applies to information technology
equipment (same as CISPR Pub.22), but the application
is excluded on the following equipment:
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:
· Equipment for which other regulations already exist
· In station equipment principal purpose of which is
· Industrial plant control system for which information
· Industrial, commercial and medical testing and
· Information equipment for which CISPR is conducting
· Japan Electronics and Information Technology
· Japan Business Machine and Information System
· Communication and Information Network Association
