SGD Hoffmann Group 51 Where sufficient safety lighting is not installed, rescue signs and fire protection signs must be made of material with a long-lasting luminescence. Signs with long-lasting luminescence are governed by ASR A3.4/3 and DIN 67510. These standards specify the light density values. The light density indicates the lighting intensity which the safety sign continues to emit 10 minutes after removal of the light source. It is stated in millicandela per square metre (mcd/m2). The standards specify the measured results to be obtained 2, 10, 30, 60 and 120 minutes after the end of excitation period. The values after 10 and 60 minutes can be found in the table. The standards specify that after a decay time of 10 minutes the light density should still be 80 mcd/m2 and after 60 minutes should still be 12 mcd/m2. The classification A - C is based on this, where C denotes the class with the best values. The signs should be used so that the light density measured at the point of installation after 10 minutes and after 60 minutes is not less than the values stated in the table. In order to be used according to the standards, the rescue signs and fire protection signs must achieve performance at least to class A.
