The Ramp Test is relatively simple test (though quite expensive as compared to Floor Pendulum Testing) performed on a surface where a ramp with the flooring attached is raised up one degree at a time until a person slips, when that person slips then the angle is measured and a determination of slip resistance is arrived at. Ramp Testing is good for comparative testing of floor surfaces where a determination of which surfaces of different types provides the better Floor Slip Resistance.
The Floor Ramp Test raises the floor until an operator slips
The test operator will wear standard cleated soled boots, the Contaminant used is ‘usually’ motor oil (but may be changed to a contaminant relevant to a particular environment) and the test value arrived at is known as the R-Rating – Read more about R-Ratings.
The Shod Ramp Test determines Floor R-Ratings (R9,R10,R11,R12,R13)
For bare foot type flooring environments
The test operator is bare foot and the contaminant used is soapy water is a particular dilution and the value arrived at is known as the ABC-Rating – Read more about ABC-Ratings
The Bare Feet Ramp Test determines Floor ABC-Ratings
EN-16165 – Annex A (Bare foot Test) and Annex B (Shod Foot Test), which are deemed to supersede the following (German) DIN Standards from 2022/2023....
DIN-51097 – Barefoot Ramp Test
DIN-51130 – Shod Foot Ramp Test
EN-13845 – Determines the ESB and ESF values
Limitations of the Ramp Test
Warning – There is alot of INCORRECT information around about R-Ratings readacross to Pendulum Test Values (PTV). This misleading data has lead to many Floor Slip Injury Claims, which FloorSlip know well about because we specialise in preparing Expert Witness Reports in Floor Testing. The misunderstanding has misled architects and floor specifiers when Buying New Floors in selecting Floor R-Ratings to specify floors but R-Rating should NOT be used for the purpose of specifying general floors; only where an R12 or R13 is found can this assumption be considered. Below this at R9, R10 and R11 (there is nothing below R9) there is the high likelihood a floor will fail the On-Site Floor Pendulum Test, which means the floor will not meet the HSE Requirements for Safe Floors. If you are a specifier, builder or Architect etc. in this situation, send FloorSlip a sample and we will conduct a very affordable Floor Sample Pendulum Test upon it BEFORE you spend many thousands on purchasing floors!
The bare foot test has no limitations upon the test surface as it is just skin but the test using cleated boots will change results when boots of different rubber hardness and sole / heel pattern changes.
The Ramp Test is only conducted on a limited floor area (approx. 1 meter square) and typically on new flooring so is not representative of a true installation where different Floor Wear occurs; this is where the On-Site Pendulum Floor Slip Test has its advantages.
The Ramp Test is also subject to how the operator walks (gait), the operator’s weight and foot size; all parameters, which are variable so a variable set of results will occur. Whereas the Floor Slip Pendulum Test will provide repeatable accurate readings over and over again and can be used to detect and Monitor Floor Wear.
The Ramp Test is often accompanied by a Pendulum Test but the test results end up with a Range of Pendulum Test Values, which can be misleading for floor specifiers.
