Automotive electronics testing

Automotive EMC testing

DELTA tests electronic sub assemblies (ESA) for a number of types of vehicle:

Automotive:

• Cars
• Trucks
• Buses
• Motorcycles

Machines:

• Tractors
• Forestry machines
• Dumpers
• Diggers
• Accessories and trailers

Automotive testing requires know how

The tests require trained and skilled EMC specialists and most of the testing involves special test equipment. DELTA has run EMC tests for more than 65 years. We have customized our EMC facilities to meet the automotive requirements and we have performed automotive tests on electronic sub-assemblies (ESA) for over two decades.

EMC requirements for vehicles

The electronics are located in an environment that challenges the design, and where EMC phenomena are not normally present in applications placed on solid ground. The automotive requirements often cover EMC tests as well as testing for environmental parameters.

Safety

Safety issues including safety of machinery and road safety are of particular interest. The legal requirements differ between safety and non-safety related electronic equipment, giving two different severity levels.

Manufacturer requirements

It is very common that automotive electronics must fulfil extended requirements, specified by the manufacturer of the complete vehicle. DELTA can verify almost all the extended requirements by EMC testing.

Approvals and market access - vehicular machines

Vehicular machines must be CE qualified to access the European market and a declaration of conformity (DoC) must be written and signed.

EMC standards - vehicular machines

The EMC requirements are covered by harmonized standards in the EU: EN ISO 14982, tractors and forestry machinery and EN 13309, diggers and dumpers. The non EU requirements are very similar, and they are covered by ISO 14982, tractors and forestry machinery and ISO 13766, diggers and dumpers.

Automotive in EU - e or CE marking

If the electronics are meant for automotive applications, they must meet the EMC requirements in automotive directive 2004/104/EC to qualify for access to the European market.

Automotive non EU - E marking

The non EU requirements are normally covered by UN regulation R10, but it is up to the law in each country as to whether they accept UN regulation R10 and the E marking that indicates the product is approved in a type approval procedure.

Get assistance with the type approval

DELTA co-operates with an external partner who handles the type approval procedure and who can assist with the quality system that is required.

Test report and accredited testing

Accredited testing with a test report is a must, if your product is going through a type approval.
