Active Standard: E2072 - 10
Since 2009, the U.S. codes have mentioned both UL1994 Standard for Luminous Egress Path Marking Systems and ASTM E2072 for code compliance. UL1994 tests floor-installed markings, such as stair nosing or stair treads for their floor suitability whereas E2072 currently does not test this. UL1994 performs the floor suitability testing per UL410 Slip Resistance of Floor Surface Materials. UL410 is based on ASTM D2047 Test Method for Static Coefficient of Friction of Polish-Coated Floor Surfaces as Measured by the James Machine. At the Subcommittee meeting, it was discussed and then decided to add floor-suitability testing to E2072 based on ASTM D2047.
