Immunity to Conducted Transients on Power Leads


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 components 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).


This document is scheduled for a 5 year systematic review. The document is being re-affirmed instead of being stabilized because its corresponding international standard ISO 7637-2 is currently being revised to include 48 Volt system & the latest corresponding changes in ISO 7637-3 and is targeted for publication in the next couple of years. Once ISO 7637-2 is published, it is anticipated that EMC Standards Committee will consider revising SAE J1113-11 to incorporate these changes.
