What testing and certification does the EU require for automotive electronics?

First, separate the test report from compliance

This is the most common misunderstanding in export projects. A test report proves the item was tested and the data is here; compliance additionally requires a set of documents: the technical file, a risk assessment, the declaration of conformity (DoC), and correct marking and instructions. Without the documents, a complete set of reports still will not clear customs or a customer audit.

Three lines, split by product function

One: electromagnetic compatibility

For vehicle electronics entering the EU market, EMC normally goes through ECE R10, a United Nations Economic Commission for Europe regulation that sits within a type approval system: a designated technical service issues the test report and supports the approval process.

If the customer is not pursuing whole-vehicle type approval but asks for component-level validation, the work is usually done to CISPR 25 (emissions) and the ISO 11452 series (immunity). The two routes rest on different bases, so confirm with the customer which one applies first.

Two: environmental compliance

• RoHS: restricts lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers. Testing is by homogeneous material, not on the finished unit.
• REACH: driven by the SVHC list — above the threshold there is a notification obligation, and the list keeps being updated. This is not a one-off test; a supply-chain information mechanism has to be in place.

Three: wireless functions, where applicable

If the product carries Bluetooth, Wi-Fi, cellular or GNSS, the RED (Radio Equipment Directive) is layered on. RED covers the EMC and safety requirements, but the radio frequency part must be tested separately.

Three common misjudgements

Assuming an EMC test equals whole-vehicle approval. ECE R10 is a type approval system; testing is only one step, followed by conformity of production and approval documents.

Ignoring the ongoing REACH obligation. The SVHC list is updated every year, and any change of formulation or supplier triggers a re-assessment. Many companies only check once, on first export.

Checking RoHS on the finished product but not the supply chain. RoHS is judged by homogeneous material, so one non-compliant connector plating fails the whole unit. Material declarations have to be requested from upstream.

A checklist worth preparing before export

• The product BOM and homogeneous material list (for RoHS / REACH checking)
• Material declarations or test reports for critical components
• The EMC test report (to the standard and revision specified by the customer)
• Technical file: construction drawings, schematics, instructions, label artwork
• A declaration of conformity (DoC) template

Where we stand

TMC LAB holds both CMA and CNAS accreditation and covers automotive EMC (CISPR 25 / ISO 11452 series), materials and restricted substances (RoHS / REACH) and environmental reliability testing. Our certification business covers more than 60 certification schemes in over 30 countries.

Send us the product functions, the target market and the customer requirements, and we will first map out what needs testing, which documents are required and where a third party is needed — then discuss the specific project.
