La classe R11 correspond \u00e0 une classe de r\u00e9sistance au glissement d\u00e9finie par l'essai allemand sur rampe (DIN 51130, d\u00e9sormais DIN EN 16165, annexe B).<\/strong> A floor is rated R11 when the mean angle at which test persons in safety shoes start to slip on the oil-coated surface is more than 19° and up to 27°. In practice, R11 sits in the middle of the R9 to R13 scale and is a common requirement for workshops, outdoor walkways and industrial areas where oil, grease or weather make floors slippery.<\/p>\n

Fonctionnement du test de rampe<\/h2>\n

L'\u00e9chelle R est issue d'un test de marche sur un plan inclin\u00e9. Un sujet portant des chaussures d'essai marche en position droite sur un \u00e9chantillon de rev\u00eatement de sol enduit d'huile de moteur. L'inclinaison est augment\u00e9e jusqu'\u00e0 ce que le sujet commence \u00e0 glisser. L'angle auquel cela se produit d\u00e9termine la classe R : plus l'angle est raide, plus la r\u00e9sistance au glissement est \u00e9lev\u00e9e.<\/p>\n

Le test est r\u00e9alis\u00e9 en laboratoire sur un \u00e9chantillon, et non sur le sol d\u00e9j\u00e0 pos\u00e9, et utilise de l'huile ainsi que des chaussures de s\u00e9curit\u00e9 \u00e0 crampons. Le r\u00e9sultat ne s'applique donc qu'\u00e0 des conditions de sol recouvert d'huile et avec des chaussures aux pieds.<\/p>\n

R9 \u00e0 R13 : les plages d'angles<\/h2>\n

The table below follows Annex 1 of the German workplace rule ASR A1.5 “Fußböden”.<\/p>\n\n\n\n\n\n\n\n\n\n
Classe R<\/th>\nAngle d'inclinaison<\/th>\n<\/tr>\n<\/thead>\n
R9<\/td>\n6° to 10°<\/td>\n<\/tr>\n
R10<\/td>\nMore than 10° up to 19°<\/td>\n<\/tr>\n
R11<\/strong><\/td>\nMore than 19° up to 27°<\/strong><\/td>\n<\/tr>\n
R12<\/td>\nMore than 27° up to 35°<\/td>\n<\/tr>\n
R13<\/td>\nMore than 35°<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The R class is often combined with a V value. V4, V6, V8 and V10 give the minimum displacement volume of a profiled surface (4, 6, 8 or 10 cm³\/dm²), the open space below the walking surface of a profiled floor. A requirement such as “R11 V4” therefore means both a minimum ramp angle and a minimum open volume.<\/p>\n

Ce que signifie concr\u00e8tement la norme R11<\/h2>\n

R11 is not a “non-slip” guarantee. It tells you that the surface performed within a defined band in a standardised oil test. The UK HSE points out that neither ramp method uses contaminants that are typical of real workplaces, and that R9 and R10 floors can be slippery in wet or greasy conditions. R11 gives more margin, but cleaning, wear, footwear and the actual contaminant still decide how safe a floor is.<\/p>\n

Lorsque le R11 est g\u00e9n\u00e9ralement prescrit<\/h3>\n

L'annexe 2 de la norme ASR A1.5, qui s'appuie sur la r\u00e8gle DGUV 108-003, attribue des classes minimales aux zones de travail. Voici quelques exemples de niveau R11 :<\/p>\n
