1.General
1.1This Interference-Causing Equipment Standard ts out the technical requirements
relative to the radiated and conducted radio noi emissions from digital apparatus.
1.2.1Subject to Sections 1.2.2 and 1.2.3, Sections 3 to 7 apply to every digital
apparatus, the model of which is newly manufactured in or imported into Canada
after November 22, 1997, except digital apparatus manufactured or imported
solely for export purpos.
1.2.1.1 A transition period ending May 31, 1998 is provided, within which
compliance with either ICES-003 Issue 2, Revision 1 or ICES-003
Issue 3 will be accepted. After May 31, 1998, only compliance with
ICES-003 Issue 3 will be accepted.
1.2.2Sections 3 to 7 do not apply to digital apparatus ud:
(a)in a transportation vehicle;
(b)as an electronic control, either by a public utility or in an industrial plant;
(c)in a power system, either by a public utility or in an industrial plant;
(d)as test equipment, including an oscilloscope and a frequency counter, in an
industrial, commercial or medical environment;
(e)as a medical computing device, under the direction of a licend health care
practitioner;
(f)in machinery, apparatus or equipment:
(i)the primary function of which is to apply energy to a process or material
through the action of an electric motor or a resistive heating element;
(ii)that draws a steady-state current that does not exceed:
(A)in the ca of an electric motor, 20 A RMS;
(B)in the ca of an electric heating element, ud either alone or in
conjunction with an electric motor, 50 A RMS;
(iii)that operates from an alternating current voltage supply that does not
exceed 150 V RMS; or
(iv)where the machinery, apparatus or equipment is a portable tool and has an input power that does not exceed 2 kW.
(g)in central office telephone equipment operated by a telecommunications
common carrier in a central office;
(h)in a device having a power consumption not exceeding 6 nW;
(i)in a device in which both the highest frequency generated and the highest
frequency ud are less than 1.705 MHz and which neither operates from,
nor contains provision for operation while directly or indirectly connected to
the AC power lines;
(j)solely for demonstration and exhibition purpos; or
(k)as a prototype unit.
1.2.3(1)Sections 3 to 7 do not apply to units or models of digital apparatus for
which the manufacturer, importer or owner has been granted a special
permission by the Minister.
(2)The Minister may grant a special permission where:
(a)the manufacturer, importer or owner has prented a written
application giving:
(i)the reasons for the request;
analysis bad on sound engineering principles showing that the (ii)an
unit or model of digital apparatus will not po a significant risk to
radiocommunication; and
(iii)a guarantee of compliance with all the conditions the Minister may t in the special permission.
(b)and, the Minister is satisfied that the unit or model will not po a
significant risk to radiocommunication.
(3)The special permission is valid only if:
(a)the unit bears a label stating that it is operating under special
permission and tting out the conditions of that special permission;
and
(b)the unit complies with all conditions t out in the special permission.
(4)The Minister may revoke or amend the special permission granted under
subction (2) at any time without prior notice.
1.3In accordance with the requirements of Sections 3 to 5, only one of either the
publication referred to in Section 7.1(1) or the publication referred to in Section 7.1(2)
shall be ud for compliance with this Standard.
2.Definitions
2.1In this Standard,
"digital apparatus" means an electronic apparatus that generates and us timing signals
at a rate in excess of 10,000 puls per cond and that utilizes radio frequency energy
for the purpo of performing functions including computations, operations,
transformations, recording, filing, sorting, storage, retrieval and transfer, but does not
include an ISM (industrial, scientific or medical) radio frequency generator.
"Class A digital apparatus" means a model of digital apparatus for which, by virtue of its characteristics, it is highly unlikely that any units of the model will be ud in a
residential environment, which includes a home business. Characteristics considered to
be applicable in this asssment include: price, marketing and advertising methodology,
the degree to which the functional design inhibits applications suitable to residential
environments or any combination of features which would effectively preclude its u in
a residential environment.
"Class B digital apparatus" means any model of digital apparatus that cannot qualify as
Class A digital apparatus.
3.Instrumentation
3.1Instrumentation shall be in accordance with either the publication referred to in
Section 7.1(1) or the publication referred to in Section 7.1(2).
4.Method of Measurement
4.1 A reprentative type or model of each digital apparatus shall be tested in accordance
with the measurement method described in either the publication referred to in
Section 7.1(1) or the publication referred to in Section 7.1(2).
4.2The field intensity of radiated radio noi emissions may be measured at a distance other
than that prescribed in subction 4.1 but in such ca the measurement result shall be
extrapolated to the prescribed distance in accordance with either the publication referred to in Section 7.1(1) or the publication referred to in Section 7.1(2).
