Floor Slip Testing ‘R’ Ratings R9 - R13

The Health and Safety Executive (HSE) advises and recommends using floor surfaces that meet Floor (Ramp) ‘R Ratings’ for SHOD FEET and ‘ABC Ratings’ for BARE FEET.

The R ratings (SHOD Feet)

These R / ABC ratings relate to the very expensive and non portable DIN Standard* floor RAMP test (though the portable Floor Pendulum Test does allow testing to determine equivalent ratings) the ‘R’ relates to the ‘R’ in Ramp Test. The floor type to be tested is fixed to a ramp and oil (For Shod Feet). The ramp is then raised and the test subject walks backwards and forwards wearing boots slips on the floor (the tester is attached to a safety harness to prevent slip injury). The computerised readout then determines the R ratings based on the angle of slip.

ABC Ratings (BARE Feet)

The ramp can also be used to assess floors for predominantly wet environments uch as swimming pools or showers and an ‘ABC’ floor slip Rating is given. The test subject does the test in Bare feet and water only is applied to the surface as a contaminant.

R Ratings for BARE Feet

’R’ Ratings for SHOD FEET must conform to DIN 51130

ABC Ratings for BARE Feet

’ABC’ Ratings for BARE FEET must conform to DIN 51097. ABC Ratings are used for wet floor conditions where bare feet are the norm such as saunas, Jacuzzis, public showers, swimming pools etc.

Video of Ramp Testing

A very good short video (1 minute) explaining the ramp test can be found here, the video has English Subtitles - see the video of Ramp Testing to find R Ratings

* DIN is the equivalent to British Standards in the UK and is an accepted standard in the UK DIN stands for 'Deutsches Institut für Normung' or German Institute of Standardisation. It is the standard by which floor designers and architects must specify to in some countries to conform with building regulations and to offset possible accident injury

Which Floor ‘R’ or ‘ABC’ Rating should I pick?

In general, for shod environments, a minimum of R11 is recommended on a horizontal surface where the surface is ‘likely’ to become wet. However it is suggested to always use R 12 to R 13 on any floor slope for a SHOD Environment and a floor bare foot ‘C’ rating where slopes are evident in predominantly wet environments like swimming pools or showers

BEWARE, it is often the case that the ‘R Rating’ found on flooring leaflets, websites and what is says on the packaging are often ‘over specified’ ! FloorSlip have tested many flooring types using the HSE approved Pendulum Test and found large differences between the floor samples we test are the ‘supposed’ R Ratings; the largest quantity are foreign imports which account for many UK tiles sold. Pendulum Test Values (PTV) of 40+ have been advertised when when the floor surface was wet - but only achieved just 12-15 PTV when Pendulum Floor Testing was carried out. The HSE expects a MINIMUM of 36 PTV when a floor is wet and horizontal and this value must be adjusted UP for floor slopes by approximately 2 PTV for each 1 degree of slope (A 5 degree slope would require 36PTV + 10 PTV for the slope or 46 PTV when WET)

Can I have floors checked for the R Rating (or ABC Rating)?

YES - HSE Approved floor slip pendulum test equipment to meet your duty of care and prevent slip injury claims The ramp test may not be a portable equipment nor affordable nor practical for most persons but floor PTV Values** can be easily proven through the affordable  Floor Pendulum Test; prices start from as little as £147 for off site Floor Sample Testing the and £447 for on site Pendulum Testing to BS 7976-2

**The UK HSE recommends* a minimum Floor Test Value of 36 PTV when DRY, WET or CONTAMINATED

*Be Warned - The HSE may only ‘recommend’ a minimum 36PTV (when a floor is wet and on a horizontal slope) but we are aware the HSE enforce this recommendation in the UK courts of law!

FAQ’s on Floor R Ratings

1. My Floor is DRY ‘most the time’, why do I need a floor to meet WET conditions?

Please DO NOT think the floor will always be dry. A spill from a cup of coffee or even a squashed grape will cause a slip and a slip injury claim. For example.... Costa Coffee were fined £5 Million ($7.5 Million) in Dec 2011 for a slip injury claim after a Customer slipped on spilt coffee and hurt themselves….Don’t let that business be yours - have Pendulum Floor Testing - the only floor test that can protect you and that is recognised in  a court of law in a personal injury claim

2. I have seen R9 and R10 floors for sale - won’t these do?

Please DO NOT be tempted to use R9 and R10 floor ratings as a cheaper option. R9 and R10 Floor coverings can not nor ever will meet the minimum legal standard required when wet or contaminated, which is a Pendulum Test Slip Resistance Value of of 36 PTV

As a general rule of thumb when considering floors, the harder, smoother and ‘shinier’ the floors surface (For example a marble style floor) the better the slip resistance when dry but far worse when wet or contaminated. Whereas a matt, rough or textured surface such as those found in kitchens and changing rooms will be lower pendulum test value when Dry but far better floor slip value when wet

Pendulum Test Values for 2 different floor surfaces

Two examples might be: -

Typical Floor In reception area - Smooth Polished Terrazzo Marble

Pendulum Test Value  - Dry Floor = 75 - 90  / Wet Floor = 10 - 15

Typical Floor In Kitchen - Matt finish Profiled / Rough Porcelain Floor Tile

Pendulum Test Value - Dry Floor = 45 - 55 / Wet Floor = 40 - 50

3. What R Values should my floors be to avoid Personal Injury Claims?

Ideally R13 will meet just about all circumstances (Or a C Rating for wet areas such as swimming pools). An R12 will suffice provided there are not any excessively steep slopes. If in doubt, have floor samples Pendulum Tested


Calculating the Chances of Slipping on a Floor

Friction is the resistive force to motion and is generally defined as ‘that force that acts between two bodies so as to resist their sliding over one another’. A floor with a high friction capability will provide enough ‘grip’ in most circumstances to prevent a person falling and the HSE / HSL has determined the chances of slipping on a floor rated at a minimum Slip Resistance Value of 36 is 1 in 1 million. That figure rapidly reduces though below the SRV of 36 as the HSE / HSL derived table below shows:-

Coefficient of Friction between foot and floor =

= Between 0.36 and 0.40 (x 100) = Pendulum Test Value of 36 1 in 1,000,000 Low Risk

= Between 0.34 and 0.38 (x 100) = Pendulum Test Value of 34 1 in 100,000 Moderate Risk

= Between 0.29 and 0.34 (x 100) = Pendulum Test Value of 29 1 in 10,000 Moderate Risk

= Between 0.27 and 0.32 (x 100) = Pendulum Test Value of 27 1 in  200 Moderate Risk

= Between 0.24 and 0.29 (x 100) = Pendulum Test Value of 24 1 in  20 High Risk

PTV = Pendulum Test Value

The simple graph below portrays the probability of slip. The values have been determined by PW Pye and HW Harrison in Floors and Flooring Performance  - available at
