Since 2009, the U.S. building and fire codes have referenced both UL1994 Standard for Luminous Egress Path Marking Systems and ASTM E2072 for code compliance of wall- and floor installed photoluminescent egress path markings. UL1994 tests floor-installed markings, such as stair nosing or stair treads for their floor suitability whereas E2072-10 currently does not address floor-suitability. During a January 2014 subcommittee ballot, E12.13 proposed to add ASTM D2047 Test Method for Static Coefficient of Friction of Polish-Coated Floor Surfaces as Measured by the James Machine (adopted by Underwriters Laboratories Inc as Standard UL410 and incorporated into UL1994). This ballot received one Negative vote. At a WebEx meeting on March 13, attendees discussed which one is the right machine to perform floor suitability testing; whether testing should be done only in a laboratory or also in the field; whether just a static co-efficient of friction of 0.5 should be required without indicating the machine that tests this result; if any testing is needed at all; how ASTM E2072 compares to UL1994 seeing that both are cited in the building codes as perceived equal documents. The Negative vote was accepted and the meeting outcome was to draw floor-suitability related text from the building code, e-circulate this to E12.13 and ask for feedback (attained March 14), then submit for simultaneous Sub- and Main Committee Vote. Todays ballot is based on the IBC International Building that requires these Luminous Egress Path Marking.
