A R11 \u00e9 uma classe de resist\u00eancia ao deslizamento definida pelo ensaio alem\u00e3o em rampa (DIN 51130, atualmente DIN EN 16165, Anexo 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

Como funciona o teste da rampa<\/h2>\n

A escala R resulta de um teste de marcha num plano inclinado. Um participante, cal\u00e7ado com sapatos de teste, caminha em posi\u00e7\u00e3o ereta sobre uma amostra do revestimento do pavimento que foi revestida com \u00f3leo de motor. A inclina\u00e7\u00e3o \u00e9 aumentada at\u00e9 que a pessoa comece a escorregar. O \u00e2ngulo em que isso acontece determina a classe R: quanto mais acentuado for o \u00e2ngulo, maior ser\u00e1 a resist\u00eancia ao deslizamento.<\/p>\n

O teste \u00e9 realizado num laborat\u00f3rio, numa amostra, e n\u00e3o no pavimento instalado, e utiliza \u00f3leo e botas de seguran\u00e7a com sola antiderrapante. Por conseguinte, o resultado descreve apenas condi\u00e7\u00f5es em que se usa cal\u00e7ado e em que h\u00e1 \u00f3leo presente.<\/p>\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

O que significa a R11 na pr\u00e1tica<\/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
