Division 2 Installation plaqueF1F2

249 F3After the recording equipment has been checked on installation, an installation plaque which is clearly visible and easily accessible shall be affixed onto the recording equipment. In cases where this is not possible, the plaque shall be affixed to the vehicle's ‘ B ’ pillar so that it is clearly visible. For vehicles that do not have a ‘ B ’ pillar, the installation plaque should be affixed to the doorframe on the driver's side of the vehicle and be clearly visible in all cases. After every inspection by an approved fitter or workshop, a new plaque shall be affixed in place of the previous one.

250 F4The plaque shall bear at least the following details:

• name, address or trade name of the approved fitter or workshop,

• characteristic coefficient of the vehicle, in the form ‘ w = … imp/km ’ ,

• constant of the recording equipment, in the form ‘ k = … imp/km ’ ,

• effective circumference of the wheel tyres in the form ‘ l = … mm ’ ,

• tyre size,

• the date on which the characteristic coefficient of the vehicle and the effective circumference of the wheel tyres were measured,

• the vehicle identification number,

• the part of the vehicle where the adaptor, if any, is installed,

• the part of the vehicle where the motion sensor is installed, if not connected to the gear-box or an adaptor is not being used,

• a description of the colour of the cable between the adaptor and that part of the vehicle providing its incoming impulses,

• the serial number of the embedded motion sensor of the adaptor.

250a For M1 and N1 vehicles only, and which are fitted with an adaptor in conformity with Regulation (EC) No. 68/2009 ^f1 , and where it is not possible to include all the information necessary, as described in Requirement 250, a second, additional, plaque may be used. In such cases, this additional plaque shall contain at least the last four indents described in Requirement 250. This second, additional plaque, if used, shall be affixed next to or beside the first primary plaque described in Requirement 250, and shall have the same protection level. Furthermore the secondary plaque shall also bear the name, address or trade name of the approved fitter or workshop that carried out the installation, and the date of installation.
