Homologation (Greek homologeo, ὁμολογέω, "to agree") is the granting of approval by an official authority.This may be a court of law, a government department, or an academic or professional body, any of which would normally work from a set of rules or standards to determine whether such approval should be given.
Generally, type approval is required before a product is allowed to be sold in a particular country, so the requirements for a given product will vary around the world. Processes and certifications known as type approval in English are often called homologation, or some cognate expression, in other European languages. [1] [2]
In motorsport, homologation is a testing and certification process for vehicles, circuits, and related equipment for conformance to technical standards, usually known as type approval in English-language jurisdictions. [1] [2] It confirms conformity to standards or categorisation criteria typically set by the sporting authority.
Motor vehicle type approval is the method by which motor vehicles, vehicle trailers and systems, components and separate technical units intended for such vehicles achieve type approval in the European Union (EU) or in other UN-ECE member states.
Vehicle regulations are requirements that automobiles must satisfy in order to be approved for sale or use in a particular country or region. They are usually mandated by legislation, and administered by a government body.
In organic chemistry, a homologation reaction, also known as homologization, is any chemical reaction that converts the reactant into the next member of the homologous series. A homologous series is a group of compounds that differ by a constant unit, generally a methylene ( −CH 2 − ) group.
The World Forum for Harmonization of Vehicle Regulations is a working party (WP.29) [1] of the Inland Transport Committee (ITC) of the United Nations Economic Commission for Europe (UNECE).
The WLTP replaces the old NEDC as the European homologation lab-bench procedure, which was established in the 1980s to simulate urban driving conditions for a passenger car. [8] In 1992 the NEDC was updated to also include a non-urban path (characterized by medium to high speeds), and finally in 1997 CO 2 emission figures were added, too. [9]
