This part of SAE J1113 specifies the transverse electromagnetic mode (TEM) cell test methods and procedures for testing the electromagnetic immunity of electronic components (DUTs) for passenger cars, commercial vehicles and similar applications. Methods using the constant cross-section TEM cell (Crawford TEM) and the flared cross-section TEM cell (wideband TEM) are discussed in the document. The electromagnetic disturbance considered in this part of SAE J1113 will be limited to continuous narrowband electromagnetic fields. TEM cells produce both electric and magnetic fields simultaneously. The test is directly applicable to DUTs whose height is less than 1/3 the septum height; somewhat larger modules can be tested with conditions applied. The Crawford TEM and wideband TEM cell may be used for testing within the 1/3 height condition without demonstrating field uniformity within the cell, if the test set-up complies with the other provisions of this standard.
This test can be used for two purposes:
a
Testing the immunity of DUTs with major field coupling to the DUT and wiring harness;
b
Testing the immunity of DUTs with major field coupling to the DUT.
The methods defined in this document have some significant differences from ISO 11452-3. Careful deliberation has been given to the need to diverge from the international standard. The primary differences are the method of bringing leads from the DUT out of the TEM cell and the inclusion of the wideband TEM cell.
Immunity measurements of complete vehicles are generally only possible by the vehicle manufacturer. The reasons, for example, are the high costs of a vehicle sized absorber lined chamber, preserving the secrecy of prototypes or the large number of different vehicle models. Therefore, the TEM cell is useful for research, development, and quality control. This test method is also required by many vehicle manuafcturers.
Rationale
The May 2000 version of SAE J1113-24 is being updated to reflect the latest information regarding the test.
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.
