Slip Resistance in Public Areas
The GripGlass™ pattern is specifically designed to maximise effective contact area achieved between an average pedestrian footprint and the slip-resistant GripGlass™-treated area, while minimising 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 affected by 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.
| Rating | Angle (degrees) |
| R9 | ≥6; <10 |
| R10 | ≥10; <19 |
| R11 | ≥19; <27 |
| R12 | ≥27; <35 |
| R13 | ≥35 |
