European Automotive Compliancy (e-marking)

For Europe, among the
directives and regulations on motor vehicles, their trailers systems and components, specific test and approval requirements for automobiles and ESA are covered by directive 27/245/EC and all its amendments (for e-marking). Other well known international automotive test standards, but also used as basis for the EU automotive directive, are ISO 11452-2/-4 (for Immunity upto 2GHz v. 30V/m and 200MHz v. 60mA) per Annex IX, ISO 10605 (for ESD upto 30kV), ISO 7637-2 (for Immunity against Pulses) per Annex X, and CISPR25 (for emissions in 30M-1GHz: broad-band max. 52~63dBuV/m, narrow-band max. 42~53dBuV/m) per Annex VII and VIII to protect receivers.
Type Approval for Europe requires Conformity of Production (CoP, e.g. ISO 9000 QS) including (initial) audit by the official Type Approval Authority (TAA) and a Conitnuous Compliancy program (sample testing), whereas ESA volunatarily following the European e-mark Type Approval route are not excluded.




The United Nations Economic Commission for Europe UNECE specification ECE regulation 10 (Rev 3) provides similar EMC type approval requirements, however recognised more widely, such as eastern Europe and other countries in the world (for E-mark marking).

FYI: Vehicles with two or three wheels are regulated under directive 97/24/EC , whereas land, farm and forest machines are regulated under directive 75/322/EEC .


American Automotive Compliancy

For the U.S.A., specific test and approval requirements for automobiles are defined in:
SAE J551 (standard for Vehicle, available parts: 1, 2, 4, 5, 11, 12, 13, 15, 17)
SAE J1113 (standard for ESA, available parts: 1, 2, 4, 11, 12, 13, 21, 22, 24, 26, 27, 41, 42)


Australian Automotive Compliancy

For Australia, automotive products which are sold independently of the vehicle must meet the ACA, currently ACMA EMC regulatory arrangements. A common example of this is car audio equipment, which falls under EN 55013, CISPR 13 or AS/NZS CISPR 13. However the ACA (currently ACMA) has entered into an agreement with the Federal Chamber of Automobile Industries (FCAI) for its members. The Federal Chamber of Automotive Industries FCAI is the peak industry organisation representing the automotive industry in Australia . The FCAI's membership include the four passenger motor vehicle manufacturers and all major international brands importing and marketing passenger, light-commercial and four-wheel drive vehicles and motor cycles in Australia etc. Under the agreement, a voluntary Code of Practice from the FCAI covers products that are pre-installed in vehicles (ie: fitted accessories and engines). Please note that automotive products manufacturers who are not members of the FCAI will still be required to meet the Australian EMC regulatory requirements for any vehicles or automotive parts or accessories they provide to the Australian market. These manufacturers will need to display the C-tick on those products which are Compliance Level 2 or 3 products. For example, the EMC standard AS/NZS 2557 (spark ignition engines, equivalent to CISPR 12) applies to vehicles and motor boats propelled by an internal combustion engine, electrical means or both (combustion and electrical). Although immunity is voluntary in Australia , the ACA (currently ACMA) recommends that suppliers consider immunity issues at the product design stage. There are general provisions under the Radiocommunications Act 1992 where suppliers are subject to heavy penalties if their products are found to cause interference to the radiofrequency spectrum. The EMC arrangements are underpinned by two basic regulatory requirements: 1) product compliance with a relevant EMC standard and 2) C-Tick labelling. The C-tick labelling compliance requirements of motor vehicles and motor accessories will depend upon whether the manufacturer is a member of the FCAI and whether the products they supply are only supplied as an integral part of the vehicle. Regardless of whether the manfacturer is an FCAI member or not, they must still meet an applicable standard for all radiocommunications products. The European e-mark is not recognised in Australia as a mark of compliance for EMC. Automotive products are required to comply with the ACA's EMC regulatory arrangements and must be labelled with the C-tick as per normal arrangements for a host of other electrical and electronic products unless otherwise specified (as above for FACI members).

Requirements from car manufacturers

Specific (additional or extended) requirements are usually defined by individual manufacturs (VW, PSA, BMW, Honda, Renault) and AEMCLRP (GM, Ford , Chrysler). Well know additional requirements are specified for pulse/interruptions phenomena on the boardnet, and immunity requirements against radar pulses (1.2-1.4GHz, 2.7-3.1GHz). Test laboratories usually require formal recognition by the respective car manufacturers.
