R10 v's PTV-36 .......... The legal differences!


In March 2010 the law for slip resistance changed and changed, to be inline with the Equality ACT 2010 that superseded the Disabled Discrimination ACT (DDA-Regs'). Before March 2010, the UK adopted and practiced using the DIN method of testing slip resistance across flooring finishes. The DIN standard is the method that produces a testing result, such as an R10 along with higher or lower ratings, based on the outcome of the material being under test. 

Since the Equality ACT 2010 took effect in March 2010, the correct and LEGAL testing method has been the pendulum test method (PTV). The pendulum tests puts out 3 classes of slip rating: high, moderate or low potential for slippage. 

We strongly urge all of our clients, when they ask for the reliable 'R10' that they should rather be thinking about a PTV (pendulum test value) as it's in line with the current law here in the UK. If however, you're based in the UK but designing a project that's outside of the UK, you of course need to assess what the law is for that particular country but on the most part, the DIN method is still recognised across the world.

If there is an accident or slip related issue on your project then you will be hauled into a legal dispute of which, all specifications will be drilled into for the party at fault, the solicitors will look at: 

  • Slip resistance value for the flooring material installed.
  • Cleaning regime
  • Footwear used at the time of the issue 

If they uncover that the tile for our example was specified as an R10 then you will lose your standing and be culpable for the claim. If you used the correct PTV for the floor then they will look onwards to points 2 & 3 that are listed above, such as cleaning and footwear. 

Whilst we still get asked multiple times a day for R10 rated tiles, we continue to educate without bias, the correct manner of specification. 

Bedrock wanted to simply, write a few words that will help you clarify the legal situation, for slip resistance here in the UK. 

If someone you are collaborating insists that you are to use an R10 for a project here in the UK, you must challenge this and if it helps, refer them to this article. Our team understand this law and are happy to advise anyone wishing to know a little more about why the UK changed the positioning on slip resistance testing methods.
