Type Approval of Systems, Components and Separate Technical UnitsThis page was last updated on 14th February 2020
Whole Vehicle Type Approval is dependent on each of the various systems and individual components specified within the appropriate Type Approval Framework meeting the requirements of the appropriate EC instrument or UN Regulation.
There are certain items that will most likely need to be approved as an individual component or a Separate Technical Unit (STU), as well as being approved as part of an overall system, in order to meet the requirements of the appropriate Whole Vehicle Type Approval Framework.
In addition to the requirements for Whole Vehicle Type Approval, a number of standards also apply to after-market products as well as Original Equipment Manufacturer (OEM) parts. Examples of these include tyres, glazing, indirect vision components, exhaust systems and replacement brake linings.
