Floor Slip ‘R’ Ratings R9 - R13 HSE Approved floor slip pendulum test equipment to meet your duty of care and prevent slip injury claims

The Health and Safety Executive (HSE) advises and recommends using floor surfaces that meet floor slip ‘R Ratings’ for environments where shod feet are found; and ‘A,B,C Ratings’ for wet floor conditions where bare feet are the norm (such as swimming pools).

In general a minimum of R11 is recommended on a horizontal surface but Ideally R12 to meet most circumstance. Always use R 12 to R 13 on any slopes. But always PROVE THE VALUE by HSE Approved and Recommended Pendulum Testing

Slip Prevention ‘R’ Ratings for Flooring Surfaces in SHOD FEET Environments to avoid slip injury claims

R Value relation to Pendulum Test Value for Shod Feet Environments

The UK Laws on Floors insist on a minimum Pendulum Test Value of 36 when DRY, WET or CONTAMINATED

Please DO NOT trust the ‘R Rating’ found on flooring leaflets, websites and what is says on the packaging; they are often ‘over specified’ ! … as an example; we’ve tested many imported tiles (the quantity of which accounts for many UK tiles) where Pendulum Test Values of 40+ have been advertised when when the floor surface was wet - they often achieved just 12-15 when Pendulum Tested;

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 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 your floors Pendulum Tested - the only test that can protect you and that is recognised in  a court of law in a personal injury claim

Please DO NOT be tempted to use R9 and R10 floor ratings as a cheaper option;  R 9 and R 10 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

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 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

What R Value should my floors be to avoid Personal Injury Claims in Bare Feet?

R Value relation to Pendulum Test Value for Bare Feet Environments

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

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 claims

A ramp, laid with the flooring material to be tested, is raised in varying degrees until a person, wearing either a specified shoe type or in bare feet, slips on the floor. The test is performed a number of times using dry floors, wet flooring and contaminated floor surfaces.

The results are averaged and an R rating is given to that floor type, and equates to its potential to prevent slips on the flat.  

Always use a minimum of R12 and ideally R13 rating for any slopes; even a 5 degree slope needs a minimum Pendulum Test Value (SRV) of 45
