This document contains limits and procedures for the measurement of radio disturbances in the
frequency range of 150 kHz to 5 925 MHz. This document applies to vehicles, boats, internal
combustion engines, trailers, devices and any electronic/electrical component intended for use
in vehicles, boats, trailers and devices. Refer to International Telecommunications Union (ITU)
publications for details of frequency allocations. The limits are intended to provide protection
for on-board receivers installed (per the manufacturer’s guidelines) in a vehicle from
disturbances produced by components/modules in the same vehicle.
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.), WiFi, V2X, and Bluetooth.
This document 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 document are recommended and subject to modification as agreed between
the customer (e.g. vehicle manufacturer) and the supplier (e.g. component manufacturer). This
document is also intended to be applied by vehicle manufacturers and suppliers which are to
be added and connected to the vehicle harness or to an on-board power connector after delivery
of the vehicle.
This document 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.
The emission requirements in this document are not intended to be applicable to the intentional
transmissions from a radio transmitter as defined by the ITU including their spurious emissions.
NOTE 1 This exclusion is limited to those intended transmitter emissions, which leave the EUT as radiated
emissions and are coupled onto the wire line in the measurement setup. For conducted transmissions on frequencies
intentionally produced by the radio part of an EUT, this exclusion does not apply.
NOTE 2 It is usual for customers and suppliers to use radio regulation standards to manage the effect of spurious
emissions from a radio transmitter unless limits of spurious emission are agreed in the test plan.
