Translate name
STANDARD published on 1.4.2026
The information about the standard:
Designation standards: SAE J1113/4
Publication date standards: 1.4.2026
SKU: NS-1273406
Country: American technical standard
Category: Technical standards SAE
Annotation of standard text SAE J1113/4 :
This SAE Standard defines a method for evaluating the immunity of automotive electrical/electronic devices to radiated electromagnetic fields coupled to the vehicle wiring harness. The method, called bulk current injection (BCI), uses a current probe to inject RF onto the wiring harness in the frequency range of 1 to 400 MHz. BCI is one of a number of test methods that can be used to simulate the electromagnetic field.
The test method refers to ISO 11452-4 (please refer to ISO 11452-4 for test procedures).
In addition to ISO 11452-4, this test method also includes a differential bulk current injection (DBCI) test. DBCI is described in Section 4 of this document.
