Light Reflectance Value Testing
Since the publication in 2004 of 'Access to and Use of Buildings' in the Building Regulations, concerning provisions to assist the disabled, including those who are visually impaired, light reflectance value testing has become important to designers, manufacturers and building owners.
The guidance highlights the need for certain surfaces and features to "contrast visually" with their surroundings. These areas of particular interest, which can be found in any public building, such as hospitals, schools, shopping centres, hotels, 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
- Sanitary fittings and grab bars.
At Lucideon, thanks to our many years experience in colour measurement and standards, we are able to offer light reflectance value testing and consultancy. We have full knowledge of the current guidance in the Regulations and in the relevant Codes of Practice, BS 8300: 2001 - that adequate visual contrast is provided if the Light Reflectance Values (LRV) of the contrasting areas differ by at least 30 points.
We work with manufacturers who are often being advised to publish LRV values for their products (for example, by the Guild of Architectural Ironmongery) and with designers and end-users who are increasingly demanding to know LRV values.
