Specifying Photoluminescent Safety Signs

The principle standard covering photoluminescent products in the Marine and Offshore industry is ISO 15370 Low Location Lighting - Arrangement. This Standard requires a luminance decay performance in the place of use of 15mcd/m2 after 10 minutes and 2 mcd/m2 after 60 minutes of loss of activating illumination.

This performance level is typical of a material meeting DIN 67510 Part 4 or ISO 17398 Classification A which is receiving between 25 and 50 lux of activating illumination.

Using Class A materials will require the minimum width of 75mm and is the absolute minimum requirement being met.

Using JALITE AAA materials with rapid charging high initial brightness improves greatly the effectiveness of LLL systems under the normal lighting conditions providing the "above minimum requirement" philosophy of most safety professionals. The added advantage of higher luminance performance materials allows designers to consider narrower width LLL and hence improved aesthetics.

Improving the purchase specification of photoluminescent safety signs

Specifiers and purchasers can easily improve the specification of photoluminescent safety products both safety signs to meet SOLAS regulations and Low Location Lighting.

ISO 17398 Safety colours and safety signs — Classification, performance and durability of safety signs provides an excellent basis for improving purchase specifications.

All JALITE Marine Signs are made from exceptional JALITE AAA. Meeting Class B performance according to ISO 17398 even at low activation from installed lighting.
