This SAE Recommended Practice covers the recommended testing techniques for the determination of electric field immunity of an automotive electronic device when the device and its wiring harness is exposed to a power line electric field. This technique uses a parallel plate field generator and a high voltage, low current voltage source to produce the field.
Rationale
Off-road vehicles often negotiate areas crossed by high voltage (up to 1000000 V) power transmission lines. During operation, the vehicle electronics will be exposed to intense AC electric fields. The field intensity from power lines is expected to be higher for these “off-road” vehicles than “on-road” vehicles because of their close proximity to these power lines.
There is no known comparable SAE or ISO test method.
The Electromagnetic Compatibility (EMC) Standards Committee reports to the Electrical Systems Group of the Motor Vehicle Council. The Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports related to all aspects of EMC as it applies to surface vehicles and their components regardless of propulsion method or electrical system voltage. Phenomena addressed include radio frequency emissions, radio frequency immunity, electrostatic discharge (ESD) immunity, and transient voltage emission and immunity. The Electromagnetic Immunity (EMI) Task Force and Electromagnetic Radiation (EMR) Task Force have been developed under the committee's scope. Participants in the Electromagnetic Compatibility (EMC) Standards Committee include OEMs, suppliers, consulting firms, government, and other interested parties.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
