Whether parquet flooring or wooden stairs – oiled wooden surfaces with HS Profiöl are in demand. No wonder: they not only look naturally beautiful, but also feel pleasantly warm underfoot and can be re-oiled at any time. But the question that concerns many professionals and builders is: Are oiled wooden surfaces also slip-resistant – and where is this particularly important?When it comes to safety, the legislator takes a close look.
The Workplace Ordinance (ArbStättV) and the Technical Rule ASR A1.5 "Floors" clearly state: Where there is a risk of slipping, the floor must achieve a certain slip resistance class (R-class).
And how is that tested? With the ramp test: A wooden sample is coated with oil, placed on an inclined plane, and slowly tilted. A tester with standardized shoes walks on it – until they slip. The angle of the first slip determines the class. Sounds like balance training in the lab – but it is a strictly standardized procedure according to EN 16165.
Whether wooden floors or stairs – tested safety is required everywhere. Indoors, the following applies:
- R9: dry areas like offices – here the minimum level of safety is sufficient.
- R10: schools, kindergartens or sales areas – wherever many feet are on the go.
- R11: more heavily used or damp areas like entrance areas, canteens or sanitary facilities.
- R12/R13: the realm of commercial kitchens and slaughterhouses – wood prefers to say: "No, thank you."
The accredited institute specializes in wood surfaces and tests strictly according to EN 16165. Result: an independent test certificate – instead of a pretty private label.
With HS Profiöl, your floors retain their look – and your steps their grip.
R10 as standard, R11 with the 2K variant – tested and officially confirmed.
