Slip Rating For Floor Tiles

[Dan]

SLIP RATING FOR FLOOR TILES IN THE UK

Floorslip.co.uk recommnds minimum ptv36 as Ray has said before now. But actually it perhaps should be more than that?

Who else is clued up on this?

I had a nightmare with this last year, client was insisting on a certain type of tile and wouldn't listen about safety aspects. It was on a slope directly off the pavement into a shop, I had to get all this info to show them and eventually convince them to change it otherwise I was walking away.

I'd never even heard of the pendulum test until Ray said it. So perhaps something others need to get clued up on the slip rating for floor tiles too.

I've just read the other thread about this and I made that mistake too, went back with all the R ratings then found out that's a waste of time and had to find out all the PTV's

 

[Dan]

Yeah apparently they're quite relaxed with the R rating and tend to over assume the tiles r rating quite a bit.

Pendulum test is the one the trust.

And if you're to over engineer a little like everything else in the tiling world (cutter breakers, tile adhesives and grouts, tile sealers etc) then you want PTV38 or PTV 40 ish.

well had a tile shop ask me to check a tile speced for a hotel project had R10 rate tested it for them it came out bang on ptv 36 .but other R10 have been as low as ptv 20 so i have no trust in the R rating .

ptv 36 1 in a million . to bring things into balance friday night out of a million people 10% get drunk spend the rest of the night falling over thats 100 thousand people .

Sorry I got those the wrong way round didn't I!

You want the 1 in a million or even less.

The 1 in 100,000 is what you don't want. As you say.

PTV 51 is in the green. How many millions can walk on it for 1 to slip on that floor?

 

[Rizzle from the Portizzle]

i would say the same number /the higher values are more to deal with floors that will due to work being carried out suffer high contamination every day ie garage work shops .restarant kitchens .
