So it has nothing to do with the quality of the tiles, just you might slip on your arse if you're a clumsy prat...??
@3_fall - great bit of information.
Thank you.
UKSRG have recently done comparisons to compare PTV and R ratings and found that the R ratings are very sporadic. Seen several cases of R9's (RAK Lounge Matt) being more anti-slip than a few R11's because of its micro-texture. If a slip case ever goes to court, R's are thrown out as being unreliable, and the HSE's recommended test results are used, which is the PTV.
We're in the slow process of phasing out R ratings as they are only reliable if someone is tiling a ramp that is likely to be covered in oil! We've even had to send a 1000 sqm order of 20mm external porcelain back to a factory as it wasn't suitable for external use, lol. Claimed it was R11 but only scored 18 in wet conditions (See 3_fall's table)..... in comparison, the Lounge scored 50.
