Advanced Technical Evaluation Criteria:

The KT16 document serves as the reference for evaluating aerodynamic components. The information provided below is extracted from this document, but it is crucial to adhere to KT16 guidelines as well as relevant regulatory standards.

Requirements for New Modifications : DTC Aerodynamic Pedestrian Certification Fussgängerschutz Zertifikat

The installation of aerodynamic components is classified as a modification subject to declaration and evaluation in accordance with Swiss legislation. Under the Federal Road Traffic Act (LCR, RS 741.01) and the Ordinance on Technical Requirements for Vehicles (OETV, RS 741.41), the vehicle owner must notify the Road Traffic and Navigation Service (SAN) in Switzerland of any modifications. Modified vehicles must undergo a pre-use inspection in accordance with Article 34 of the Federal Road Traffic Act (LCR).To avoid complications during homologation, it is recommended to use parts with appropriate certification, such as ABE (General Operating Permit), DTC test reports, or EG/ECE compliance certificates. Aerodynamic components may be homologated without documents only if all the requirements specified in the KT16 document, as well as the stipulations defined by the Ordinance on Technical Requirements for Vehicles (OETV), are strictly adhered to.Proof of material impact resistance is imperative. Necessary tests must be conducted by accredited certification bodies in accordance with Article 16 of the OETV. TüV test reports are also accepted, but TüV certificates alone are insufficient under Article 11 of the Ordinance on Vehicle Testing (OEV, RS 741.411)

Modified Front Design: DTC Aerodynamic Pedestrian Certification Fussgängerschutz Zertifikat

For any modification to the front end of a vehicle, it is crucial to comply with specific pedestrian protection requirements under the following European and Swiss directives:

• Regulation (EC) No 78/2009 and Directive 2003/102/EC: These regulations impose stringent pedestrian protection requirements for passenger and commercial vehicles. According to Article 6 of Regulation (EC) No 78/2009, any modification affecting front-end components, such as fenders, hoods, and air intakes positioned at a height from the ground between 1000 mm and 2100 mm, must be assessed to ensure pedestrian safety.
• Modifications such as openings with a diameter greater than 16 cm or additional carbon coatings must also comply with pedestrian protection requirements specified in Article 7 of Regulation (EC) No 78/2009.

When these criteria are met, a test report issued by an accredited certification body is required to certify that the modified vehicle does not pose an increased risk to pedestrians in the event of an accident. Testing must be conducted according to methods defined in ISO 12769 and in accordance with Article 5 of Directive 2003/102/EC.

Compliance with Pedestrian Protection Directives:

(Regulation No 78/2009/EC and Directive 2003/102/EC)

• From June 1, 2006: Passenger vehicles [M1] and M1-derived commercial vehicles [N1] with EC type approval and a maximum authorized weight up to 2500 kg must meet the pedestrian protection requirements stipulated in Article 3 of Regulation (EC) No 78/2009.
  • Exception: A vehicle can demonstrate that it is not subject to these requirements if specific conditions are met.
• From January 1, 2013: Passenger vehicles [M1] and M1-derived commercial vehicles [N1] without EC type approval (e.g., vehicles from the United States) with a maximum authorized weight up to 2500 kg must also comply with pedestrian protection requirements.
• From March 1, 2015: Passenger vehicles [M1] weighing over 2500 kg and all commercial vehicles [N1] with EC type approval must adhere to pedestrian protection standards defined by European and Swiss regulations.
• From August 24, 2019: Passenger vehicles [M1] weighing over 2500 kg and all non-EC type-approved commercial vehicles [N1] (e.g., vehicles from the United States) must also comply with pedestrian protection requirements.

Recognized Certification Centers:

• DTC (DTC Testing Center): Accredited by OFROU for performance and safety testing of automotive components, including impact resistance and aerodynamic compliance.
• FAKT (Forschungsgesellschaft Automobiltechnik e.V.): Recognized expertise center for performance and durability testing of composite parts, specializing in mechanical evaluations and aerodynamic simulations.

Important Note: DTC Aerodynamic Pedestrian Certification Fussgängerschutz Zertifikat

As of July 7, 2009, under Regulation No 78/2009/EC, material validation expertise alone is no longer sufficient to demonstrate compliance with pedestrian protection requirements. Compliance must be confirmed by a comprehensive test report, including an in-depth technical evaluation of the impacts of modifications on pedestrian safety. Tests must consider not only the material resistance but also its integration within the context of pedestrian safety standards.Swiss authorities, such as SAN, require strict adherence to pedestrian safety regulations for modified vehicles. Swiss manufacturers and importers must provide adequate documentation to prove that modifications meet applicable standards. The responsibility for verifying the compliance of modified vehicles lies with the client or the entity commissioning the modifications.
