ISO 11452-1 Component Test Methods for Electrical Disturbances from Narrow Band Radiated Electromagnetic Energy - Part 1: General Principles and Terminology

EUROLAB laboratory provides testing and compliance services within the scope of ISO 11452-1 standard. Developed by the International Organization for Standardization (ISO), this part of the ISO 11452 standard specifies general conditions, defines terms, gives practical guidelines, and sets out the basic principles of component testing used in other parts of ISO 11452 to determine the immunity of electronic components of passenger cars and commercial vehicles to electrical disturbances. .

ISO 11452-1 Component Test Methods for Electrical Disturbances from Narrow Band Radiated Electromagnetic Energy - Part 1: General Principles and Terminology

The electromagnetic disturbances considered are limited to continuous narrowband electromagnetic fields. A wide frequency range (dc and 11452 Hz to 15 GHz) is allowed for immunity testing of components in this and other parts of ISO 18.

In recent years, an increasing number of electronic devices have been incorporated into vehicle designs to control, monitor and display various functions. It is necessary to take into account the electrical and electromagnetic environment in which these devices operate.

Electrical and radio frequency disturbances occur during the normal operation of many motor vehicle equipment. They are produced in a wide frequency range with various electrical properties and can be distributed to onboard electronic devices and systems by transmission, radiation, or both. Narrowband signals generated from sources on or off the vehicle can also be connected to the electrical or electronic system affecting the normal performance of electronic devices. Such narrowband sources of electromagnetic disturbance include mobile radios and broadcast transmitters.

The characteristics of the components' immunity to propagated degradation should be determined. The ISO 11452 series provides a variety of test methods for evaluating component immunity properties. Not all test methods need to be used for a particular device (DUT) being tested. For example, lane line and transverse electromagnetic (TEM) cell testing methods provide very similar exposure to DUT.

Only tests required for the DUT to replicate the use and installation site should be included in the test plan. This will help ensure a technically and economically optimized design for potentially sensitive components and systems.

The ISO 11452 series is not designed as a product specification and cannot function as a single product. Therefore, no specific value was given for the test severity level.

Protection from potential failures should be considered as part of total vehicle verification as described in ISO 11451, which covers vehicle testing methods. The component testing method described in the ISO 11452 series will be performed prior to vehicle testing. Due to vehicle shape, equipment and component location differences, compliance with ISO 11452 parts does not guarantee compliance with ISO 11451 parts. However, ISO 11452 series component tests are required to provide sufficient confidence prior to integration into the vehicle.

Among the services provided by our organization within the framework of material testing services, there are also ISO 11452-1 standard tests. Do not hesitate to contact our laboratory EUROLAB for your testing and certification requests.
