Scope This SAE Standard defines methods and apparatus to evaluate electronic devices for immunity to potential interference from conducted transients along battery feed or switched ignition inputs. Test apparatus specifications outlined in this procedure were developed for component installed in vehicles with 12 V systems (passenger cars and light trucks, 12 V heavy-duty trucks, and vehicles with 24 V systems). Presently, it is not intended for use on other input/output (I/O) lines of the device under test (DUT).
The January 2006 version of this standard has been revised to re-insert Pulse 4, Pulse 5a, and Pulse 5b. All corresponding information has also been added to the main body and appendices. These pulses were originally deleted from the March 2002 version of the document (by referencing to ISO 10650-2). Since there is no equivalent SAE version of the ISO 10650-2, these pulses are re-inserted to provide specifications of in a SAE document. Function Performance Status Classifications utilized in Appendix B has also been updated to reflect the latest changes in SAE J1812.
