(Main)Vehicles, boats and internal combustion engines - Radio disturbance characteristics - Limits and methods of measurement for the protection of on-board receivers
Vehicles, boats and internal combustion engines - Radio disturbance characteristics - Limits and methods of measurement for the protection of on-board receivers
This International Standard contains limits and procedures for the measurement of radio
disturbances in the frequency range of 150 kHz to 2 500 MHz. The standard applies to any
electronic/electrical component intended for use in vehicles, trailers and devices. Refer to
International Telecommunications Union (ITU) publications for details of frequency
allocations. The limits are intended to provide protection for receivers installed in a vehicle
from disturbances produced by components/modules in the same vehicle. The method and
limits for a complete vehicle (whether connected to the power mains for charging purposes or
not) are in Clause 5 and the methods and limits for components/modules are in Clause 6.
Only a complete vehicle test can be used to determine the component compatibility with
respect to a vehicle’s limit.
The receiver types to be protected are, for example, broadcast receivers (sound and
television), land mobile radio, radio telephone, amateur, citizens' radio, Satellite Navigation
(GPS etc.), Wi-Fi and Bluetooth. For the purpose of this standard, a vehicle is a machine,
which is self-propelled by an internal combustion engine, electric means, or both. Vehicles
include (but are not limited to) passenger cars, trucks, agricultural tractors and snowmobiles.
Annex A provides guidance in determining whether this standard is applicable to particular
equipment.
This International Standard does not include protection of electronic control systems from
radio frequency (RF) emissions or from transient or pulse-type voltage fluctuations. These
subjects are included in ISO publications.
The limits in this standard are recommended and subject to modification as agreed between
the vehicle manufacturer and the component supplier. This standard is also intended to be
applied by manufacturers and suppliers of components and equipment which are to be added
and connected to the vehicle harness or to an on-board power connector after delivery of the
vehicle.
Since the mounting location, vehicle body construction and harness design can affect the
coupling of radio disturbances to the on-board radio, Clause 6 of this standard defines
multiple limit levels. The level class to be used (as a function of frequency band) is agreed
upon between the vehicle manufacturer and the component supplier.
This standard defines test methods for use by Vehicle Manufacturers and Suppliers, to assist
in the design of vehicles and components and ensure controlled levels of on-board radio
frequency emissions.
Vehicle test limits are provided for guidance and are based on a typical radio receiver using
the antenna provided as part of the vehicle, or a test antenna if a unique antenna is not
specified. The frequency bands that are defined are not applicable to all regions or countries
of the world. For economic reasons, the vehicle manufacturer is free to identify what
frequency bands are applicable in the countries in which a vehicle will be marketed and which
radio services are likely to be used in that vehicle.
As an example, many vehicle models will probably not have a television receiver installed; yet
the television bands occupy a significant portion of the radio spectrum. Testing and mitigating
noise sources in such vehicles is not economically justified.
The vehicle manufacturer should define the countries in which the vehicle is to be marketed,
then choose the applicable frequency bands and limits. Component test parameters can then
be selected from this standard to support the chosen marketing plan.

Vozila, plovila in naprave z motorji z notranjim zgorevanjem - Karakteristike občutljivosti za radijske motnje - Mejne vrednosti in metode merjenja za zaščito sprejemnikov na krovu
Ta standard opredeljuje preskusne metode, namenjene za proizvajalce in dobavitelje vozil, za pomoč pri oblikovanju vozil in sestavnih delov ter zagotavljanje nadziranih ravni frekvenčnih emisij v vozilih.
Podaja smernice glede omejitev za preskušanje vozil, osnovanih na delovanju običajnega radijskega sprejemnika z anteno kot delom vozila ali s preskusno anteno, kadar uporaba posebne antene ni določena. Opredeljeni frekvenčni pasovi se ne uporabljajo za vse regije ali države sveta. Iz ekonomičnih razlogov lahko proizvajalec identificira frekvenčne pasove, ki se uporabljajo v državah, v katerih namerava tržiti vozilo, in radijske storitve, ki se bodo predvidoma uporabljale v vozilu.
Primer: čeprav televizijski frekvenčni pasovi zasedajo velik del radijskega spektra, številni modeli vozil verjetno ne bodo vključevali vgrajenega televizijskega sprejemnika. Z vidika ekonomičnosti postopek preskušanja in omejevanja virov hrupa v takih vozilih ni upravičen.
Proizvajalec vozila mora opredeliti, v katerih državah namerava tržiti vozilo, in nato izbrati ustrezne frekvenčne pasove in omejitve. V tem primeru se lahko opravi ustrezna izbira parametrov preskušanja sestavnih delov iz tega standarda v skladu z izbranim načrtom trženja.
