Slip Resistance in Public Areas
Lumascape ’ s GripGlass™ pattern is specifically designed to maximize effective contact area achieved between an average pedestrian footprint and the slip resistant GripGlass™ treated area , while minimizing the impact on luminaire output and performance .
Independent laboratories using German standard DIN S1130 , have determined the GripGlass™ treated surface area achieves an R11 ( or greater ) performance rating , using the Oil Wet Ramp Test . This R11 rating relates to the surface area effected with the GripGlass™ treatment only ( see diagram ), and is not applicable to the entire fixture including untreated glass area and surrounding stainless steel or brass cover .
A brief explanation of this test is as follows .
OIL-WET RAMP TEST METHOD
Two test persons , wearing standard test shoes , are used to determine the angle of inclination at which safe walking no longer occurs , after the pedestrian surface material being tested is coated with engine lubricating oil . The angles of inclination obtained are used to assess the friction characteristics of the test surface .
