Description of BS AU 145e:2018 2021

This British Standard specifies requirements for retroreflecting number plates for vehicles, including requirements for:

  1. colorimetric and photometric properties;

  2. adequate contrast between background and characters in NIR wavelengths to demonstrate compatibility with automatic number plate recognition (ANPR) systems; and

  3. resistance to bending, impact, abrasion, corrosion, solvents, weathering and extremes of temperature.

The British Standard does not specify requirements for number plates fitting, which is prescribed by statutory regulations.

NOTE 1 The appropriate regulations of The Road Vehicles (Display of Registration Marks) Regulations 2001 (as amended) [1] specify requirements for fixing, size and type of letters, numbers and spacings of retroreflecting number plates.

NOTE 2 Retroreflecting number plates can be manufactured from any material which performs satisfactorily in service, providing the requirements of this British Standard are met.
