Automotive Standards


Automotive EMC Standards

Automotive standards addressing electromagnetic compatibility (EMC) are developed mainly by CISPR, ISO and SAE. CISPR and ISO are organizations that develop and maintain standards for use at the international level. SAE develops and maintains standards mainly for use in North America. In the past, SAE developed many EMC standards which were eventually submitted to CISPR and ISO for consideration as an international standard. As the SAE standards become international standards, the equivalent SAE standard is then withdrawn as a complete standard and reserved for use to document differences from the international standard.

ISO 10605

ISO 10605 Road Vehicles — Test Methods for Electrical Disturbances from Electrostatic Discharge This International Standard 10605 specifies the electrostatic discharge (ESD) test methods necessary to evaluate electronic modules intended for vehicle use. It applies to discharges in the following cases:

  • ESD in assembly
  • ESD caused by service staff
  • ESD caused by occupants
ESD applied to the device under test (DUT) can directly influence the DUT. ESD applied to neighboring parts can couple into supply and signal lines of the DUT in the vehicle and/or directly into the DUT. This International Standard describes test procedures for evaluating both electronic modules on the bench and complete vehicles. This International Standard applies to all types of road vehicles regardless of the propulsion system (e.g. spark-ignition engine, diesel engine, electric motor). This International Standard is based in part on IEC 61000-4-2 and describes vehicle-specific requirements. This International Standard does not apply to pyrotechnic modules. Preview Standard

ISO 11452-10

ISO 11452-10 Road Vehicles - Component Test Methods for Electrical Disturbances from Narrowband Radiated Electromagnetic Energy - Part 10: Immunity to Conducted Disturbances in the Extended Audio Frequency Range Immunity measurements of complete road vehicles can generally only be carried out by the vehicle manufacturer, owing to, for example, high costs of absorber-lined shielded enclosures, the desire to preserve the secrecy of prototypes or a large number of different vehicle models. For research, development and quality control, a laboratory measuring method can be used by both vehicle manufacturers and equipment suppliers to test electronic components. ISO 11452-1 specifies general test conditions, definitions, practical use and basic principles of the test procedure. ISO 11452-10 specifies a conducted voltage test method and procedure for determining the immunity of electronic components of passenger cars and commercial vehicles, regardless of the propulsion system (e.g. spark-ignition engine, diesel engine, electric motor). The method is applied to each individual device under test (DUT) lead and is applicable to all power and output leads, as well as low frequency analogue leads. The method is particularly useful in evaluating DUTs with acoustic or visible display functions. The disturbances considered in this part of ISO 11452 are limited to continuous narrowband electric voltage waveforms. Preview Standard

ISO 11452-4

ISO 11452-4 Road Vehicles - Component Test Methods for Electrical Disturbances from Narrowband Radiated Electromagnetic Energy - Part 4: Harness Excitation Methods ISO 11452-4 specifies harness excitation test methods and procedures for determining the immunity of electronic components of passenger cars and commercial vehicles regardless of the propulsion system (e.g. spark-ignition engine, diesel engine, electric motor). The bulk current injection (BCI) test method is based on current injection into the wiring harness using a current probe as a transformer where the harness forms the secondary winding. The tubular wave coupler (TWC) test method is based on a wave coupling into the wiring harness using the directional coupler principle. The TWC test method was developed for immunity testing of automotive components with respect to radiated disturbances in the GHz ranges (GSM bands, UMTS, ISM 2,4 GHz). It is best suited to small (with respect to wavelength) and shielded device under test (DUT), since in these cases the dominating coupling mechanism is via the harness. For DUTs which are larger than a wavelength (e.g. 0,1 m at 3 GHz), direct field coupling to the printed circuit board (PCB) becomes of equal importance. The user of the TWC test method should take this into account and determine the applicability of the method. The electromagnetic disturbances considered in this part of ISO 11452 are limited to continuous narrowband electromagnetic fields. Preview Standard

ISO 11452-8

ISO 11452-8 Road Vehicles - Component Test Methods for Electrical Disturbances from Narrowband Radiated Electromagnetic Energy - Part 8: Immunity to Magnetic Fields ISO 11452-8 specifies tests for electromagnetic immunity of electronic components for passenger cars and commercial vehicles, regardless of the propulsion system (e.g. spark-ignition engine, diesel engine, electric motor), to magnetic fields. These sources are classified into “internal magnetic field” (sources internal to the vehicle, e.g. vehicle electro-mechanical motors, actuators) and “external magnetic field” (sources external to the vehicle e.g. power transmission lines, generating stations). To perform this test, the device under test (DUT) is exposed to a magnetic disturbance field. The radiating loop method can be applied to small DUTs or to larger DUTs by positioning the coil in multiple locations. The Helmholtz coil is sometimes used as an alternative method. This technique is limited by the relationship between the size of the DUT and the size of the coils. The electromagnetic disturbances considered in this part of ISO 11452 are limited to continuous narrowband electromagnetic fields. Preview Standard

SAE J1113-11

SAE J1113-11 Immunity to Conducted Transients on Power Leads This SAE Standard J1113-11 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). Measurement Philosophy Installed electrical equipment is powered from sources which contain, in addition to the desired electrical voltage, transients with peak values many times this value, caused by the release of stored energy during the operation of a relay and/or other loads connected to the source while starting and/or turning off the vehicle. These tests are designed to determine the capability of equipment to withstand such transients. The tests are performed in the laboratory (bench tests). Bench test methods give results, which also allow comparison between laboratories. These tests may not cover all types of transients, which can occur in a vehicle. The test pulses described in Section 8 are, however, characteristic of typical pulses. To ensure proper operation of a vehicle in the electromagnetic environment, vehicle testing should be performed in addition to bench testing. Preview Standard

SAE J1113-21

SAE J1113-21 Electromagnetic Compatibility Measurement Procedure for Vehicle Components - Part 21: Immunity to Electromagnetic Fields, 30 MHz to 18 GHz, Absorber-Lined Chamber This SAE J1113-21 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.

SAE J1113-24

SAE J1113-24 Immunity to Radiated Electromagnetic Fields; 10 kHz to 200 MHz - Crawford TEM Cell and 10 kHz to 5 GHz - Wideband TEM Cell This SAE Standard J1113 specifies 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:

  1. Testing the immunity of DUTs with major field coupling to the DUT and wiring harness
  2. 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, for research, development and quality control a laboratory measuring method shall be applied by the component manufacturer. Preview Standard

SAE J1113-25

SAE J1113-25 Electromagnetic Compatibility Measurement Procedure for Vehicle Components - Immunity to Radiated Electromagnetic Fields, 10 KHz to 1000 MHz - Tri-Plate Line Method This SAE Standard J1113-25 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. This permits its use to frequencies above that of a TEM cell of the same physical size. Note that although the construction of the TPL limits generation of uniform electric and magnetic fields to frequencies below 500 MHz, experience has shown that the TPL may be used at frequencies up to 1 GHz and still provide reasonable and repeatable test results. This may only occur if the test setup requirements (i.e., DUT plus 1 meter of cable) and characterization procedures delineated in this SAE Standard permits its use to frequencies above that of a TEM cell of the same physical size. Note that although the construction of the TPL limits generation of uniform electric and magnetic fields to frequencies below 500 MHz, experience has shown that the TPL may be used at frequencies up to 1 GHz and still provide reasonable and repeatable test results. This may only occur if the test setup requirements (i.e., DUT plus 1 meter of cable) and characterization procedures, delineated in this SAE Standard are followed. The lack of side walls also means that the TPL must be used within an RF shielded enclosure to prevent RF energy, radiated from the TPL from interfering with near-by electronic devices. To prevent potential resonances and reflected waves within the shielded enclosure from distorting the fields produced within the TPL, the test chamber walls and ceiling must be lined with RF absorbing material. These issues are discussed in greater detail in the body of this is followed.

SAE J1113-27

SAE J1113-27 Electromagnetic Compatibility Measurements Procedure for Vehicle Components - Part 27 - Immunity to Radiated Electromagnetic Fields - Mode Stir Reverberation Method 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. The 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 SAE Standard J1113-27 addresses the Mode Stir (Continuous 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. This Standard provides the component design and test engineers with a test procedure and the performance requirements necessary to quickly evaluate the immunity of electronic devices to radiated electromagnetic fields early in the design stage as well as pilot and production stages. This method is an alternative to testing in an absorber lined chamber. Ensuring electromagnetic compatibility early in the development stage will minimize costly changes later in the program and will prevent excessive component level hardening during full-vehicle level testing. The reverberation test method performs a dual function. The primary function of the method is to provide a bench test procedure correlative to vehicle level radiated immunity testing in the anechoic chamber and at mobile transmitter sites. The method can quickly evaluate the relative performance of different designs of the same device. Preview Standard
