1.General
1.1This Interference-Causing Equipment Standard ts out the technical requirements
relative to the radiated and conducted radio noi emissions from radio frequency
心灵小故事lighting devices (RFLD).
1.2.1Subject to subctions 1.2.2 and 1.2.3, Sections 3 to 7 apply to every RFLD that
is manufactured or imported into Canada after October 31, 1998, except RFLD
manufactured or imported solely for export purpos.
1.2.1.1 A grace period ending April 30, 1999 is provided, after which
compliance with ICES-005, Issue 1 is mandatory.
1.2.2Sections 3 to 7 do not apply to RFLD ud:
(a)solely for demonstration and exhibition purpos; or
(b)as a prototype unit.
1.2.3(1)Sections 3 to 7 do not apply to units or models of RFLD 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;
(ii)an analysis bad on sound engineering principles showing that the
unit or model of RFLD will not po a significant risk to
radiocommunications;
(iii)a guarantee of compliance with all the conditions the Minister may
t in the special permission; and,
(b)the Minister is satisfied that the unit or model will not po a significant
risk to radiocommunications.
(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.
2.Definitions
2.1In this Standard,
"RFLD" includes any lighting device that us radio frequency energy to excite a gas
inside a bulb in order to produce light, including an electronic ballast and a bulb.
"Class A RFLD" means a model of RFLD 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清蒸大虾最简单的做法
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 RFLD" means any RFLD that cannot qualify as a Class A RFLD.
3.Instrumentation
3.1 Radio Frequency Receivers
3.1.1Receivers shall be in accordance with the publication referred to in
subction 7.1(1).
3.2Line Impedance Stabilization Network
3.2.1The line impedance stabilization network (LISN) shall be in accordance with the
publication referred to in subction 7.1(2).

3.3.1 A calibrated tuned half-wave dipole antenna or any other linearly polarized
鲜花和荆棘
antenna, provided the results obtained with such antennas are correlatable with
results obtained with a tuned half-wave dipole, shall be ud for the measurement
of radiated emissions.
4.Method of Measurement
4.1General Requirements
4.1.1During the testing period, the RFLD shall be:
圆脸适合什么刘海(a)operated in accordance with the manufacturer's specifications;
(b)configured in a manner which tends to maximize its emissions characteristics
in a typical application; and,
(c)operated for a sufficient period of time to ensure that normal operating
conditions exist during the testing period.
4.1.2Any measured levels of radio noi exceeding the limits specified in Section 5
shall be deemed to be emissions from the RFLD, unless it is demonstrated that
the emissions originate from ambient sources which cannot be suppresd and
that the emissions from the RFLD do not exceed the limits specified in Section 5.
4.2Line-Conducted Noi Emissions Measurements
4.2.1Testing shall be performed using the test system prescribed in the remainder of
this subction and illustrated in Annex III except that where the u of an LISN
is not possible at a ur's installation, a line probe must be ud. The testing at
the ur's installation site shall be modified in accordance with subction 4.4.3.
4.2.2Conducted emissions shall be measured by scanning the frequency range of 0.45
to 30 MHz. All emissions that exceed a value of 20 dB below the limits
prescribed in subction 5.1 shall be recorded.
4.2.3The floor of the test site is required to be an earth-grounded conducting surface,
which may be the metal floor of a shielded test chamber. A conducting vertical
plate or screen of at least 2 m by 2 m in size shall be electrically connected to the
conducting ground plane along its entire length. The conducting ground surface
is to be at least 2 m by 2 m in size, and shall extend 40 cm beyond the projection
(footprint) of the RFLD when facing the vertical plate, and at least 50 cm beyond
the projection on the remaining three sides.
4.2.4The RFLD under test shall be placed:
(a)on a nonconductive platform 1 m by 1.5 m in size;
(b)at least 80 cm away from the LISN;
(c)40 cm away from the vertical grounded conducting surface or, where a
shielded enclosure is ud, 40 cm from any one vertical grounded surface of
