Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 22902-7 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3,
Electrical and electronic equipment.

Introduction
This part of ISO 22902 describes environmental conditions and tests to be applied to AMI-C compliant
electrical and electronic equipment and some subcomponents directly mounted in or on the vehicle. It is not
intended for direct application to all parts or assemblies that are part of that equipment. For example, it should
not be directly applied to integrated circuits (ICs) and discrete components, printed circuit boards (PCBs),
gages, displays, controls, etc. that are subassemblies of the equipment. Electrical, mechanical, climatic and
chemical loads permitted for such parts and assemblies can be quite different than those described in this part
of ISO 22902.

Part 7:
Physical specification
1 Scope
The scope of this part of ISO 22902 is limited to conditions and testing at the equipment level; it does not
include all conditions and testing necessary for complete verification and validation of the vehicle system.
Environmental and reliability testing at lower and higher levels are required to ensure that vehicle quality and
reliability objectives are met.
It addresses the following requirements relating to the design and manufacture of automotive components and
of devices intended to be used in vehicles:
⎯ Environment. The conditions in and on a vehicle that a component or device must function within. These
conditions include chemical, climatic, electromagnetic and mechanical factors and stress.
⎯ Power management. The requirements for power supply and delivery from a vehicle to its components
and the devices used in that vehicle.
⎯ Interconnectivity. The requirements for delivering data within a vehicle. These requirements differ
depending on the delivery method selected by the automaker or supplier.
⎯ Packaging. The standards for locating, securing, protecting, and enclosing or covering components and
devices.
⎯ Homologation. An overview of the legal requirements that apply to AMI-C compliant vehicles.
⎯ Diagnostic functional requirements. An overview of the sensing and analysis that AMI-C compliant
components and devices shall support. This section also recommends characteristics of diagnostic tools.

3 Environment
3.1 Mounting location in the vehicle
In current or future designs of road vehicles, systems, components and devices are mounted in almost any
location of the vehicle. The environmental requirements for each specific application depend highly on its
mounting location. Each location in the vehicle has a distinct set of environmental loads. For example, the
range of temperatures in the luggage compartment differs from the range of temperatures in the passenger
compartment. Devices installed in doors are exposed to a high number of mechanical shocks from door
slamming.
3.2 Component or device compliance test procedure
The following tests shall be conducted as appropriate to ensure that physical components or devices comply
with performance requirements. The pass/fail criteria listed for each test constitutes the performance
requirements for the parameter being tested. Perform the sequences of a test in order, as indicated by the

3.2.11.1 Vibration pass/fail criteria
The following items are the requirements for measuring audible noise under vibration:
⎯ The units shall be tested with a sinusoidal acceleration from 10 to 200 Hz.
⎯ Acceleration amplitude shall be 1G 0 peak from 10 to 100 Hz and 0.5 0 peak from 101 to 200 Hz.
⎯ Frequency sweep shall be linear, constant time per frequency, and have a duration of 10 minutes to cover
10 to 200 Hz range.
⎯ Under the above vibration profile, the unit shall not emit an overall “A” weighted noise SPL greater than
70 dB using 1/3 octave analysis for the 25 Hz to 20 kHz frequency range, 1/8 second integration time per
sample and peak hold mode.
⎯ Place the microphone between 0.1 and 1 meter from the unit. Adjust reported noise measurements to
reflect equivalent SPL at 0.1 meter. The above noise requirements (70 dB maximum SPL) are for the
0.1 meter placement.
3.3 Component or device electromagnetic compatibility test procedure
This standard establishes verification requirements for the control of the electromagnetic interference
characteristics (emission and susceptibility) of electronic, electrical, equipment and subsystems designed or
procured in compliance with this standard requirements. Such equipment and subsystems may be used
independently or as an integral part of other subsystems or systems.
The following tests shall be conducted as appropriate to ensure that physical components or devices comply
with this standard performance requirements. The pass/fail criteria listed for each test constitutes the
performance requirements for the parameter being tested. Perform the sequences of a test in order, as
indicated by the sequence number.
