Slip resistance, and what it means in the UK
This is worth reading carefully, because two different tests get used interchangeably and they are not the same thing.
- Infinity classify the matt finish as R9 under DIN 51130, the German inclined ramp test. Satin and polished finishes carry no R rating.
- UK projects are normally specified to a Pendulum Test Value (PTV) under BS 7976, following UK Slip Resistance Group guidance. This is a different test method and an R rating cannot be converted into a PTV.
- A PTV is measured on the actual finish, and results change with wetness, contamination, cleaning regime and installed condition. It requires independent testing, which is why manufacturers rarely publish one.
- We do not hold PTV data for these slabs. Where slip resistance is critical, for example a wet area, a level access threshold or a public circulation route, we recommend independent pendulum testing of the specified finish before it is confirmed.
Talk to us early where flooring is in scope. We would rather flag this at specification stage than have it come up on site.
What the numbers mean
- Water absorption of 0.05% is ten times better than the standard requires. The slab is effectively non-porous, so it does not stain from within and never needs sealing.
- Breaking strength rises sharply with thickness. 900 N at 6mm suits cladding and vertical work. 12mm at 3,500 N is the usual worktop choice. 20mm at 10,000 N suits outdoor kitchens and heavy use.
- Abrasion below 145 mm³ against a 175 mm³ limit means the surface holds its finish in high-traffic areas.
- Frost and thermal shock both return no damage, which is what allows the same slab to be used inside and outside on a scheme.
- Chemical resistance of A, LA and HA covers household chemicals, low and high concentration acids and alkalis on matt and satin finishes.

Infinity Surfaces in UK projects
Large format porcelain performs where surfaces take daily punishment and still have to look immaculate. These UK hospitality projects use Infinity Surfaces slabs supplied by Clay International.
Frequently asked questions
Are Infinity porcelain slabs slip rated?
The matt finish is classified R9 under DIN 51130, the German ramp test. Satin and polished finishes are not rated. UK projects are normally specified to a Pendulum Test Value under BS 7976, which is a different test and requires independent testing on the actual finish. We do not hold PTV data, so where slip resistance is critical we recommend independent pendulum testing before the finish is confirmed.
What technical standard are Infinity Surfaces slabs made to?
Infinity Surfaces large format porcelain is manufactured to EN 14411 Annex G and tested to the EN ISO 10545 series. Declared results are published in the technical characteristics table above, and specific test certificates are available on request.
What is the water absorption of large format porcelain?
Infinity Surfaces slabs record a water absorption of 0.05% or less, against a standard requirement of 0.5% or less under EN ISO 10545-3. That is what makes the material virtually non-porous and removes the need for sealing.
Do you provide datasheets for a specification or BREEAM submission?
Yes. The documents on this page cover most requirements, and we can supply specific test certificates, EPD and sustainability credentials documentation on request. Call +44 (0)20 8971 7948 or email info@clayinternational.co.uk with the standards your submission requires.
How strong is porcelain by thickness?
Breaking strength rises with thickness. Under EN ISO 10545-4 Infinity slabs achieve 900 N at 6mm, 3,500 N at 12mm and 10,000 N at 20mm, against a standard requirement of 700 N to 1,300 N.
