The automotive standards covering electromagnetic compatibility are mainly written by SAE, ISO and CISPR. The SAE standards are developed for North America, where ISO and CISPR are developed for the international market. The SAE organization also develops standards for the international market but the numbers are very small. The European union have their own EMC directive 2004/104/EC which supersedes 95/54/EC. The United Nations automotive standard UNECE Reg10 is also used by all UNECE members.
Large number of automotive standards in North America, Europe and elsewhere in the world are also organized by the automotive industry itself. The SAE, ISO, CISPR, UNECE Reg 10 and Automotive EMC directive 2004/104/EC are some well-known automotive organizations writing standards. Some of these standards are voluntary and others are legislated here in North America, Europe and everywhere in the world. UNECE Reg10 is an electromagnetic compatibility standard, every vehicle and electronic sub-assembly (ESA) sold in any of the UNECE member countries should be compliant to this standard. There are 58 to 64 countries and 1 union (EU) on the list. So far, the United States is not part of UNECE R10.
UNECE Reg10 and Automotive EMC directive 2004/104/EC are widely used for ‘e’ and ‘E’ mark approvals. In Europe, a complete vehicle and electronic sub-assemblies (ESA) are required to comply by the EMC directive. The ‘e’ and ‘E’ type approval is used instead of the CE mark. For the type approval, the vehicle manufacturers must also provide a statement of frequency bands, power levels, antenna positions and installations of RF transmitters. This is a mandatory requirement even if the vehicle is not equipped with the RF transmitter at the time of type approval but have the capability. This is in-line with many of the radio certification guidelines.
QAI is fully equipped to perform testing for automotive vehicles and sub-assemblies. We have paid special attention to designing the test facility, particularly its shielded rooms. QAI have designed shielded rooms in a way that the resonant modes at low frequencies don’t introduce any additional errors. If the automotive vehicle won’t fit in our 3m, 5m or 10m chambers or at the OATS, QAI has full capability to perform all the testing onsite, making it much easier for the manufacturer to complete the compliance testing in a timely manner.
QAI have added EM Test System that can provide all the automotive transient test pulses including the load dump such as 5a and 5b referenced in ISO 7637-2:2004 & ISO 16750-2 standards. The EM Test System is completely configurable and programmable to provide OEM’s specific and custom-made test pulses. QAI can now provide testing to hundreds of automotive test standards including, but not limiting to those outlined by BMW, Ford, Volkswagen, General Motors, Honda, Toyota, John Deere, Hyundai, Jaguar and many more!
QAI’s ISO 17025 accredited EMC laboratories have been offering full EMC/EMI testing services for automobiles and automotive electronic sub-assemblies since 2010. The Electromagnetic Compatibility testing includes conducted emissions, radiated emissions and susceptibility testing, which can be performed In-Situ (On Site) or in our Semi-Anechoic Chambers. The testing includes CISPR 12, CISPR 25, ICES-002, SAE J1113, UN ECE Reg10 and the ISO 7367 series of standards. For large vehicles, QAI can travel to your facility and test on-site.
