Self-luminous EXIT signs, on the other hand, contain radioactive tritium, have a limited life expectancy (10, 15 or 20 years) that must be clearly visible on the outside of the installed sign. Both are non-electrical technologies, yet photoluminescent EXIT signs are non-radioactive and non-toxic. Are photoluminescent exit signs the same as self-luminous exit signs?Ī. Also, ASTM E2072-10 does NOT require floor suitability testing of a marking. When this standard ASTM E2072-10 is used to show compliance with codes or standards, the manufacturer should have an agreement with an organization that is acceptable to the Authority Having Jurisdiction for follow-up factory inspection services. Photoluminescent liquid products can only obtain a Luminance Test Report from an NRTL – Nationally Recognized Testing Laboratory, like UL or ETL-Intertek in compliance with ASTM E2072-10.

Underwriters Laboratories Inc explains on its website for UL1994-listed markings: “Paint or pigment material must be pre-applied (at the manufacturing facility) to a substrate field application of photoluminescent pigment (by painting, spraying, or similar method) directly to building materials or surfaces is not permitted due to uncontrolled application variables deemed significant for product performance.” Can photoluminescent paint be UL1994-listed as egress path marking?Ī. So p/l materials have to accomplish bright, long lasting performance with only half the illuminance and half the length of activation time.

The more stringent IBC/IFC codes on the other hand require just 1 fc = 10.8 lux of fluorescent lighting for only 60 minutes. For NYC, luminance was measured following activation by 2 fc = 21.6 lux of fluorescent lighting for 120 minutes. NYC Department of Buildings required its own distinct set of tests for a p/l material to obtain Material- and Equipment Acceptance (MEA). Are NYC MEA listed products also IBC/ IFC codes compliant?Ī: No. The IBC and IFC requirements indicate that all handrails shall be marked on the top surface of the handrail for its entire length with a solid and continuous stripe of minimum one-inch width. May I apply the handrail marking in my emergency staircases on the wall behind the handrail?Ī: No. You find a list of OSHA approved NRTLs at

OSHA, Occupational Safety and Health Administration has recognized certain testing facilities that provide product safety testing and certification services to manufacturers, e.g., in compliance with photoluminescence-related standards such as UL924 for code-compliant EXIT signs and UL1994 for code-compliant Egress Path Marking Systems. NRTL stands for Nationally Recognized Testing Laboratory.
