10、 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
11、 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 elec
12、trotechnical 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
13、 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 iden
14、tifying 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. ISO 22902 consists of the following parts, under the general title Road vehicles Automotive multimedia interface: Part 1: General t
15、echnical overview Part 2: Use cases Part 3: System requirements Part 4: Network protocol requirements for vehicle interface access Part 5: Common message set Part 6: Vehicle interface requirements Part 7: Physical specification BS ISO 22902-7:2006vIntroduction This part of ISO 22902 describes enviro
16、nmental 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
17、 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 describ
18、ed in this part of ISO 22902. BS ISO 22902-7:2006blank1Road vehicles Automotive multimedia interface 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 co
19、mplete 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 comp
20、onents 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
21、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, secur
22、ing, 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 s
23、ection also recommends characteristics of diagnostic tools. 2 Normative references The following referenced documents are indispensable for the application of this document.

The environmental requirements
33、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 do
34、ors 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.
