The recommendations have been drawn up to encourage uniformity of application. The aim of this standard is to promote wider understanding of non-electrical low mounted way guidance systems, to encourage uniformity of application and to give advice on their most effective use within buildings.
The time period to saturation may depend upon the type of photoluminescent pigment, excitation lighting and excitation illuminance. Luminance measurements should be taken at 1, 10, 30, 60 min following the interruption of the excitation lighting which may be achieved with a suitable hood at the point of test. Changes in level should be delineated by wall mounted components indicating the pitchline of a flight of stairs or contour of each tread of a flight of stairs, single steps and ramps.
The inter-relationships of specific forms of emergency lighting are illustrated in Figure 1. It gives recommendations on the factors that need to be considered in the design, installation and wiring of electrical emergency escape lighting systems, to provide the lighting performance needed for safe movement of people if the normal lighting supply fails. For undated references, the latest edition of the publication referred to applies.
However there is a tendency to a saturation luminance performance for a particular light bs526 and excitation illuminance. Please fill this form, we will try to respond as soon as possible.

Fifth edition, November Also that the risk assessment identifies the risk to people entering a premises and that the measures the assessor is required to take include the provision of safe means of escape taking into account the needs of people with disabilities including visual impairment.
The beginning, passage and end of the change of level needs to be clearly marked. Luminance measurements should be taken at points of lowest and highest illuminance and average values may be calculated. Worldwide Standards We can source any standard from anywhere in the world.
Owing to the developing nature of the technology, a review of this part of BS will commence three years after the date of publication, as opposed to the usual five early review period.
For marking of the exit door or exit surround, the width of the luminous elements should be at least 50 mm. It is the constant aim of BSI to improve the quality of our products and services.
On failure of the normal lighting supply, the photoluminescent system emits the stored energy over a period of time with diminishing luminance.
