What is the requirement for instruments for SVA tests? |
|
The Single Vehicle Approval (SVA) test is for any non Type Approved car, light goods vehicle or motorcycle that has been imported. It is also for any vehicle which is amateur built or contains donor parts from previously registered vehicles. Motor caravans and ambulances can also be tested under the SVA Scheme. The tests are currently completed at a number of VOSA testing stations across the country. The Vehicle and Operator Services Agency (VOSA) run a number of services to ensure vehicles are safe on the roads. Any vehicle imported, that has not been 'Type Approved' or any amateur built vehicles (such as a kit car), has to undergo a pre-registration test before it can be driven in the UK. This is known as a Single Vehicle Approval test (SVA). It is carried out to ensure vehicles on the road meet UK government safety and environmental standards. The vehicle must be fitted with a speedometer capable of indicating speed in MPH at uniform intervals not exceeding 20mph at all speeds up to the design speed of the vehicle (a 140mph speedo cannot be fitted to a vehicle capable of 170mph) and must be capable of being read by the driver at all times of the day or night. For all true speeds up to the design speed of the vehicle, the true speed shall not exceed the indicated speed i.e. at a true speed of 30mph the speedometer must not show less than 30mph. For all true speeds of between 25mph and 70mph (or the design speed if lower), the difference between the indicated speed and the true speed shall not exceed 10%. i.e. at a true speed of 40mph the vehicle shall not show more than 44mph. For information on details required for recalibrating a mechanical speedo click here The vehicle will be assessed for the associated drive line components for compatibility with the speedometer, such that the accuracy of the device is unlikely to be impaired. Instruments must either be recessed into the dash panel or have rounded bezels (not half or full-vee) unless they are behind the steering wheel or within the specified zone exempt area as specified in the SVA regulations.
