This SAE Standard covers the measurement of voltage transient immunity and within the applicable frequency ranges, audio (AF) and radio frequency (RF) immunity, and conducted and radiated emissions. By reference, IEC CISPR 25 is adopted as the standard for the measurement of component emissions. In the event that an Amendment is made to the referenced edition of CISPR 25 or a new edition is published, the new IEC document shall become part of this standard six months after the publication of the IEC document. SAE reserves the right to identify exceptions to the published IEC document with the exceptions to be documented in SAE J1113-41. Emissions from intentional radiators are not controlled by this document. (See applicable appropriate regulatory documents.) The immunity of commercial mains powered equipment to over voltages and line transients is not covered by this document.

This SAE Recommended Practice provides supporting information for the emission and immunity measurement procedures defined in the SAE J1752 series of documents.

This SAE Standard defines a component-level test procedure to evaluate automotive electrical and electronic components for Conducted Emissions of transients, and for other electromagnetic disturbances, along battery feed (B+) or switched ignition inputs of a Device Under Test (DUT). Test apparatus specifications outlined in this procedure were developed for components installed in the 12-V passenger cars, light trucks, 12 V heavy-duty trucks, and vehicles with 24 V systems.

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.

The limits in this SAE Standard are designed to provide protection for receivers of all types of radio transmissions when used in buildings. As a result, receivers of radio transmissions used out-of-doors may not be protected by the limits specified. This publication applies to the emission of electromagnetic energy which may cause interference to radio reception and which is emitted from: a. vehicles propelled by an internal combustion engine, electrical means or both (see SAE J551/1 for definition); b. motorboats propelled by an internal combustion engine, electrical means or both; and c. devices equipped with spark-ignited internal combustion engines (see SAE J551/1 for definition). This publication does not apply to aircraft, traction systems (railway, tramway, and trolley bus), or incomplete vehicles.

This part of SAE J1113 specifies the direct RF power injection test method and procedure for testing electromagnetic immunity of electronic components for passenger cars and commercial vehicles. The electromagnetic disturbances considered in this part of SAE J1113 are limited to continuous, narrowband conducted RF energy. This test method is applicable to all DUT leads except the RF reference ground. The test provides differential mode excitation to the DUT. Immunity measurements of complete vehicles are generally only possible by the vehicle manufacturer. The reasons, for example, are high costs of a large absorber-lined chamber, preserving the secrecy of prototypes or the large number of different vehicle models. Therefore, for research, development, and quality control, a laboratory measuring method for components shall be applied by the manufacturer. This method is suitable over the frequency range of 250 kHz to 400 MHz.

This SAE Standard establishes a common basis for the evaluation of devices and equipment in vehicles against transient transmission by coupling via lines other than the power supply lines. The test demonstrates the immunity of the instrument, device, or equipment to coupled fast transient disturbances, such as those caused by switching of inductive loads, relay contact bouncing, etc. Four test methods are presented – Capacitive Coupling Clamp, Chattering Relay, Direct Capacitor Coupling, and Inductive Coupling Clamp.

Presently, it is not intended for use on other input/output (I/O) lines of the device under test (DUT).

This part of SAE J1113 specifies test methods and procedures for testing electromagnetic immunity (of vehicle radiation sources) of electronic components for passenger cars and commercial vehicles. To perform this test method, the electronic module along with the wiring harness (prototype or standard test harness) and peripheral devices will be subjected to the electromagnetic disturbance generated inside an absorber-lined chamber. The electromagnetic disturbances considered in this part of SAE J1113 are limited to continuous narrowband electromagnetic fields. Immunity measurements of complete vehicles are generally only performed at the vehicle manufacturer. The reasons, for example, are high costs of a large absorber-lined chamber, preserving the secrecy of prototypes, or the large number of different vehicle models. Therefore, for research, development and quality control, a laboratory measuring method shall be applied by the manufacturers.

Vehicle electrical/electronic systems may be affected when immersed in an electromagnetic field generated by sources such as radio and TV broadcast stations, radar and communication sites, mobile transmitters, cellular phones, etc. Reverberation method is used to evaluate the immunity of electronic devices in the frequency range of 500 MHz to 2.0 GHz, with possible extensions to 200 MHz and 10 GHz, depending upon chamber size and construction. Optional pulse modulation testing at HIRF (High Intensity Radiated Fields) test levels, based upon currently known environmental threats, has been added to this revision of the standard. This document addresses the Mode Stir (Continous Stirring) Reverberation testing method which has been successfully utilized as a design and production stage development tool for many years. The Mode Tuned (Stepped Tuner) Reverberation testing method is covered in the SAE J1113-28 document.

The method is used to evaluate the immunity of vehicle mounted electronic devices in the frequency range of 80 MHz to 2 GHz, with possible extensions 20 MHz to 10 GHz, depending upon chamber size and construction. Three methods for calibrating and applying electromagnetic fields are described in the document: 1) Mode Tuned Reverberation Chamber method, 2) Mode Stir (Standard) Reverberation Chamber method and 3) Mode Stir (Hybrid) Reverberation Chamber method.

This procedure covers the recommended testing techniques for the determination of radiated immunity of an automotive electronic device. This technique uses a Tri-Plate Line (TPL) operating over a frequency range from 10 KHz to 1000 MHz. This technique is limited to components which have a maximum height of equal to or less than 1/3 the height between the driven element and the outer, ground plates. A TPL, a variation of a TEM cell design, is constructed without sides to the cell. The primary advantage to the use of the TPL as opposed to a TEM cell is that its construction permits large devices to be placed within the cell with their associated cables attached without special feed through ports or adapters as required for a TEM cell. The lack of sides which would be found in a TEM cell permits easy routing of the cables to and from the Equipment Under Test (DUT). The TPL does not have a serious problem with fields reflected from the side walls as does with the TEM cell.
