(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
ISPR 25:2016 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 fourth edition cancels and replaces the third edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- inclusion of charging mode for electric vehicles (EV) and plug-in electric vehicles (PHEV),
- the methods for chamber validation have been included,
- test methods for shielded power supply systems for high voltages for electric and hybrid electric vehicles have been included,
- overall improvement.

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.
