# EMC Directive boundary for vehicle equipment

When vehicle equipment needs EU vehicle type approval, an EMC Directive declaration of conformity, both checks, or separate vehicle-specific sourcing.

*Artifact Guide* *EU*

## EMC Directive vehicle equipment boundary

Vehicle electrical and electronic equipment can sit under EU vehicle legislation, the EMC Directive, or a separate radio-equipment route depending on how it is supplied and installed.

Use this page to document the boundary between vehicle type-approval evidence and EMC Directive apparatus evidence without treating every in-vehicle accessory the same way.

For vehicle equipment, the key EMC Directive question is whether electromagnetic compatibility is already dealt with more specifically by EU vehicle legislation. Article 2(3) of Directive 2014/30/EU says the EMC Directive does not apply, or ceases to apply, where the same essential requirements are laid down more specifically by other Union legislation. Commission vehicle-equipment guidance then separates complete vehicles, OEM spare parts, aftermarket equipment tied to UNECE Regulation 10 functions, other aftermarket equipment, and accessories that are simply used in vehicles.

## Start with the vehicle-equipment category

The Commission guidance endorsed by the EMC Working Party frames the boundary as a category exercise for vehicle equipment. Vehicles in categories L, M, N, T and O, and equipment forming part of those vehicles when vehicle legislation applies, require EU vehicle-legislation approval for EMC and do not use an EMC Directive declaration of conformity for that same EMC question.

A matching OEM spare part can also fall outside both routes when it is intended for the original vehicle, clearly marked as a spare part by an identification number, and identical and from the same manufacturer as the corresponding OEM part for an already type-approved vehicle.

Aftermarket equipment needs closer review. If it falls within EU vehicle legislation, is within UNECE Regulation 10, is related to the Regulation 10 immunity-related functions, and is not the OEM spare-part case, the vehicle-approval route applies and the EMC Directive declaration route does not. If the aftermarket equipment is intended for installation in motor vehicles but is not related to those Regulation 10 functions, the Commission table points to an EMC Directive declaration of conformity instead.

- Record whether the item is a vehicle or vehicle-integrated part, an OEM spare part, aftermarket equipment under UNECE Regulation 10, aftermarket equipment outside the Regulation 10 immunity-function route, or other equipment used in a vehicle.
- For category D aftermarket equipment, keep the EMC Directive declaration of conformity and show how the declaration addresses the limits referenced in paragraph 3.2.9 of UNECE Regulation 10.
- For category E accessories, such as devices connected to vehicle USB ports or cigarette-lighter sockets and not otherwise covered by the vehicle categories, treat the product as requiring EMC Directive apparatus evidence unless another EU law takes over.

*Placement: after evidence section*

## Separate vehicle approval, EMC Directive, and RED evidence

Use this boundary page to document why a vehicle accessory follows EU vehicle legislation, the EMC Directive, RED, or a blocked evidence path that needs vehicle-specific sourcing.

- [Open Research Copilot](/solutions/research-copilot.md): Check vehicle-equipment scope and evidence gaps with cited outputs.
- [Talk through implementation](/contact.md): Review vehicle, EMC Directive, and RED evidence before product release.

## Do not use the EMC Directive to replace vehicle type approval

The boundary is not a choice of the easier evidence file. If the equipment is in the vehicle-approval side of the Commission table, the useful compliance file is the vehicle-specific approval evidence, Regulation 10 classification, affected vehicle category, and installation conditions. An EMC Directive technical file alone does not answer the type-approval question.

For aftermarket electrical or electronic sub-assemblies, the Commission guidance points users to a Regulation 10 classification flow. The first questions are whether the ESA is intended for fitment in vehicles and whether it is passive. The flow then considers restrictions to immobilised-vehicle use, charging-coupling functions, wiring-harness connection, type-approved interfaces, and whether the item is mechanically fastened in a way that cannot be removed without tools.

When the available EMC grounding does not include the underlying vehicle-approval certificate, UNECE Regulation 10 test basis, or vehicle-category analysis for the exact product, treat those as separate source needs before publishing a final boundary conclusion.

- Keep the exact vehicle category, intended fitment, installation method, wiring connection, and function affected by the equipment.
- Link vehicle-approval conclusions to vehicle-specific sources, not only to the EMC Directive or a generic EMC test report.
- Escalate for separate vehicle-specific sourcing when the product may be an ESA under UNECE Regulation 10, is mechanically fixed, connects to the vehicle wiring harness, or affects immunity-related vehicle functions.

- [Guide for the EMCD (Directive 2014/30/EU)](https://ec.europa.eu/docsroom/documents/33601?ref=sorena.io) - Explains that motor-vehicle equipment subject to type approval under UNECE Regulation 10 is outside the EMC Directive route for those EMC requirements.

## Check radio equipment and other EU-law overlaps separately

The vehicle-equipment guidance expressly says it does not make a Radio Equipment Directive table because the RED does not contain the same Article 2(3)-style exception. That means a connected vehicle accessory may need a RED analysis in addition to the vehicle or EMC Directive boundary exercise when it intentionally transmits or receives radio waves.

The EMC guide states that equipment falling within the scope of the RED is not under the EMC Directive, even though the RED includes EMC essential requirements. The same guide also notes that products no longer covered by RED, such as pure wired telecom terminal equipment, may fall back to the LVD or EMC Directive if those regimes otherwise apply.

For non-radio electrical equipment, keep the analysis narrow: identify whether another EU product law lays down EMC requirements more specifically, then decide only the EMC Directive consequence for that requirement. Safety, cybersecurity, vehicle-roadworthiness, battery, or radio obligations may still need their own source-linked files.

- Flag Wi-Fi, Bluetooth, cellular, radio-determination, or other intentional radio functions for a RED scope check.
- Do not cite the EMC Directive in the EU declaration of conformity for a radio product where the product is within RED scope.
- Do not infer vehicle approval from general EMC compliance; vehicle legislation, RED, and the EMC Directive answer different parts of the product-law stack.

- [Guide for the EMCD (Directive 2014/30/EU)](https://ec.europa.eu/docsroom/documents/33601?ref=sorena.io) - Supports the RED overlap rule: radio equipment within RED scope is outside the EMC Directive, while some terminal equipment can fall back to EMC/LVD coverage.

## Evidence to keep for the boundary decision

A useful boundary file should be able to show why a reviewer should rely on vehicle approval, EMC Directive apparatus evidence, RED evidence, or a separate unresolved vehicle-specific source request. The file should not stop at a label such as automotive accessory or aftermarket device.

For EMC Directive apparatus, the Directive requires technical documentation, the relevant conformity assessment procedure, an EU declaration of conformity, CE marking where applicable, and retention of the technical documentation and EU declaration for 10 years after the apparatus has been placed on the market. The declaration must be kept aligned when design characteristics or harmonised standards used for conformity change.

For vehicle-side conclusions, keep the source that proves the vehicle route: type-approval references, Regulation 10 category and paragraph references, fitment and wiring evidence, spare-part identity evidence, and the reason an EMC Directive declaration is not the controlling evidence for that EMC requirement.

- Product identity: model, version, hardware or software revision where relevant, intended vehicle category, and installation or connection method.
- Boundary conclusion: category A, B, C, D, E, RED, or blocked pending vehicle-specific source evidence.
- Supporting evidence: EMC test reports or standards list for EMC Directive apparatus, vehicle approval or UNECE Regulation 10 evidence for vehicle-route equipment, and RED documentation for radio equipment.
- Change triggers: design changes, installation changes, supplier or OEM-part changes, radio-function changes, harmonised-standard changes, and new vehicle-specific evidence.
