Lighting Class C? We'll explain!

Minimum Safety Requirement: Lighting Class C According to ASR A1.3

ASR A1.3 (German technical rule for workplaces governing safety and health protection signage in workplaces) regulates safety and health protection signage in workplaces. It specifies that lighting class C is the minimum requirement for photoluminescent safety signs. This regulation ensures that safety signs remain clearly visible even in the event of a power outage.

DIN 67510-1: The Standard Behind Lighting Classification

The definition of the luminance class is specified in DIN 67510-1:2020-05 (German industrial standard defining the photoluminescent properties and performance requirements of safety signage materials). This standard describes the photoluminescent properties (afterglow performance) of materials, in particular their luminance over specified time periods.

Increased Safety in the Dark: Benefits of Lighting Class C Signs

All signs in Lighting Class Coffer longer afterglow duration and higher intensity, ensuring better recognition and extended visibility. In the event of a power outageorientation and safety guidance remain available for a longer period of time. The printed parameters on the edge of KNS signs allow you to read the luminance values immediately.

All signs are available in the usual quality, size, and material in Lighting Class C. These products can be easily identified by the Ultra brand designation.

Frequently Asked Questions About Lighting Class C Signs

What is Lighting Class C?

A classification for photoluminescent signs that meet defined minimum lighting levels over a specified period of time.

What is the purpose of Lighting Class C?

It ensures that safety signs remain visible for an extended period in darkness or during a power outage.

Who determines the lighting class a sign must have?

The requirements are set forth in ASR A1.3 (German workplace safety regulation) in conjunction with DIN 67510-1 (German industrial standard issued by the German Institute for Standardizatio(DIN)).

When is the use of Lighting Class C signs required?

Whenever photoluminescent safety signage is required in workplaces, for example for emergency exit and escape route markings.

Where can information about a sign's lighting performance be found?

The relevant luminance values are printed directly on the edge of the sign.

How can you tell if a sign meets Lighting Class C requirements?

By checking the luminance values and comparing them with the requirements specified in DIN 67510-1 (German industrial standard issued by the German Institute for Standardization (DIN)).
