PSPA SPECIFICATIONS & PHOTOLUMINESCENT STANDARDS

The PSPA (Photoluminescent Safety Products Association) is an association that, amongst other activities, recommends acceptable levels of performance for photoluminescent material in the industry.  

The PSPA defines their class standards in accordance with the methodology set out in the commonly used standard of DIN 67510 pt 1 whereby luminance is measured following a specific level of excitation and then calculation made to the threshold of visibility which is 0.32mcd/m².  It is however the current recommendation of the PSPA that PSPA class A luminance be achieved as a minimum. More recent recommendations and new standards indicate that class B performance should be the minimum acceptable level and the recent Fire Regulatory Reform Act re-enforces this. Furthermore, it is worth noting that for some time now the PSPA have been discussing their own current recommendation and are likely to very shortly raise their minimum recommendation to PSPA class B. 

The industry has spent a lot of time discussing standards in the recent past and many existing standards are part way through a review period. There are also other international standards which require specific performance, some being required at differing levels of excitation. Please contact us if you require any further performance data.industry has spent a lot of time discussing standards in the recent past and many existing standards are part way through a review period.
