Light Reflectance Value Testing

Published in 2013, 'Access to and Use of Buildings' in the Building Regulations is concerned with provisions to assist the disabled, including the visually impaired.  The guidance highlights the need for certain surfaces and features to "contrast visually" with their surroundings; Light Reflectance Value (LRV) testing has therefore become important to designers, manufacturers and building owners.

Areas of particular interest, which can be found in any public building (e.g. hospitals, schools, shopping centres, hotels, etc.) are:

  • Wall to ceiling and wall to floor junctions
  • Exposed edges of sloping floors
  • Seating and its surroundings
  • Leading edges of doors, door opening furniture and door surfaces
  • Stair nosings
  • Sanitary fittings and grab bars.

Thanks to our colour measurement and standards experience, we are able to offer LRV testing and consultancy.

We have full knowledge of the current guidance in the Regulations and in the relevant Codes of Practice, BS 8300: 2009 +A1:2010 - that where illuminance on surfaces is greater than 200 lux, a difference in light reflectance value should be a minimum of 20 points.

We work with manufacturers who are often advised to publish LRVs for their products (for example, by the Guild of Architectural Ironmongery) and designers and end-users who are increasingly demanding to know LRVs.
