Planning Tools

In order to simplify your planning and use of EverGlow products, clearly arranged planning tools are provided here.

Overview

The following table provides an overview on which EverGlow quality to be selected for an optical guidance system. In general, all qualities can be used for safety marking according to BGV A8. Among others, the extent of the systems to be installed is dependant upon possible hazards that might be entailed when general lighting fails and / or smoke develops.

The present table does not substitute expert planning of an optical safety guidance system onsite but provides an overview regarding quality assessment and simplifies your advance planning.

In order to implement the marking directives, EverGlow's product range includes different qualities with various intensities and basic materials. Recently developed luminescent pigments are used in all products ensuring utmost quality.

The respective quality can be seen from the first two numbers of the article number. Our table gives a simple overview. The sign size is dependent upon the required perception width and can be defined for good sighting conditions using our table of distances.

Perception Widths

Side length b x a in cm Maximum perception width in m
10,0 x 10,0 10
20,0 x 10,0 10
15,0 x 15,0 15
0,0 x 15,0 15
20,0 x 20,0 20
40,0 x 20,0 20
25,0 x 25,0 25

There are different standards regarding the design of photoluminescent safety guidance systems which are included in the planning and installation of safety guidance systems as technical rules.

In particular, DIN 67510 Part 3 describes the German state of the art regarding safety guidance systems.

On the international level, ISO 16069, as an example, specifies electrical safety guidance systems.

In order to evaluate the products relating to their lighting suitability, the standard ISO 17398 further requires the manufacturer to provide additional information on the luminance for specified excitation scenarios.

a) Excitation with standard illuminant D65 for 20 minutes at 200 lux

b) Excitation with fluorescent lamp (4,300 K) for 15 minutes at 50 lux

c) Excitation with fluorescent lamp (3,000 K) for 15 minutes at 25 lux

What does the new ASR A 3.4/3 include?

The new Workplace Directive ASR A 3.4/3 Safety Lighting, Optical Safety Guidance Systems was issued in July 2009. This Workplace Directive defines the requirements for safety lighting and optical safety guidance systems at workplaces. It gives examples for the individual systems and lighting requirements.

Luminance at the place of use shall be:

  • at least 80 mcd/m² after 10 minutes
  • not less than 12 mcd/m² after 60 minutes

In order to select the appropriate safety guidance system, a risk analysis is to be prepared by all means. In particular, the effects of a power failure as well as possible smoke development are to be considered therein. The ASR A3.4/3 requirements always refer to the place of use. The minimum intensity of illumination* at the product surface to meet this requirement is :

HI 150 products 40 lux
HI 300 products 30 lux
TL 300 products 20 lux

*measured with continuous operation of fluorescent lamp 840 LL; other scenarios on request
