NMO grants its first MID certificate for Taximeters
27 Jan 2012

This news article covers the first ever MID certificate that NMO has granted for taximeters.
NMO are pleased to announce the granting of our first EC Type Examination Certificate for a taximeter.
The EC certificate was issued in December of last year to Cygnus Automotive Ltd for their MR500 View taximeter model. Under the Measuring Instruments Directive, the EC certificate will allow Cygnus to supply the MR500 View taximeter (pictured above) in to legally controlled applications across 31 countries in the European Economic Area.
Ric Watson, Technical Manager for Cygnus Automotive commented:
“Based upon our experience with the process of obtaining MID approval for our new MR500 View taximeter, we would be delighted to recommend the services of NMO. We have found NMO to be very quick in providing quotations, responding to questions asked and suggestions made. It has been great to be able to talk directly to the engineer who is actually carrying out the work. This has helped the process go smoothly, particularly with regard to minimising delays in solving issues that have arisen.”
The approval, carried out by Grégory Glas from the National Measurement Office, ensures that the taximeter complied with the Essential Requirements of the MID through the application of the Normative Document based on OIML R21. This involved an assessment of the technical and metrological performance of the taximeter when subjected to a range of influences (including temperature, humidity and vibration) and a range of electrical disturbances. The taximeter was also assessed to ensure that it could not be tampered with (in terms of functionality, software protection, sealings and markings) and that all information is available and clear to the user.
The certificate allows a set of functionalities (fare calculation based on time or distance counting, display of rate, mode and fare, optional printing, loading of tariffs and software, recording of journey and totals information) over a range of parameters (power supply, distance measurement signal, operating temperature, speed).
Paul Dixon, Director of Certification Services at NMO commented:
“NMO is pleased to announce the granting of our first MID Certificate for taximeters. We look forward to developing this new aspect of our certification business further, and to work with manufacturers in this exciting industry.”
Additional information
As of the 30 October 2006, all new designs of taximeters that are to be used in legally controlled applications require certification under the Measuring Instruments Directive (MID) 2004/22/EC.
Following a successful assessment by the United Kingdom Accreditation Service (UKAS), NMO’s Notified Body scope under the Measuring Instrument Directive was extended by the Department for Transport, to cover Annex MI-007, module B (D and H1 in the future).
In addition, NMO can also certify taximeters in accordance with EN 50148 and the International recommendation for taximeters OIML R21. We will soon be looking to be designated by the LTPH (formerly the Public Carriage Office) in London to perform annual audit/routine testing and tariff change testing.
