Piemme presents Ardesia

The Piemme Ardesia series was inspired by natural slate, in its typical fine split finish; thanks to modern production technology, all the appeal of this sedimentary rock is reproduced in a highly natural way on the surface of latest-generation porcelain stoneware.

The surface of Ardesia provides a high standard of safety and has passed the most stringent European tests as regards sliding resistance with values R10 (footwear) and A+B (barefoot).

Ardesia’s ability to perform well as regards safety requirements makes it ideal both in dry and humid environments, in both private or public contexts. Ardesia is a top-quality surface in terms of technology and good looks; a valid finishing material for all architectural projects in which design and user safety go hand in hand.
DIN 51130: Sliding resistance with footwear

German standard describing the method for determining the sliding resistance properties of surfaces trodden on wearing accident-prevention footwear according to EN 345: the tiles are positioned, wet with engine oil (SAE 10W30), on a surface with gradient gradually increased until the person taking part in the test slips. According to the angle in which the person loses grip, the classification coefficient “R” is determined on a continuum of 5 intervals: between R9 (minimum friction) and R13 (very high friction).

DIN 51097: SLIDING RESISTANCE BAREFOOT WET AREAS CLASSIFICATION GROUPS

German standard describing the method for determining the sliding resistance properties of surfaces trodden on with bare feet: the tiles are positioned, wet with a soapy solution, on a surface with gradient gradually increased until the person taking part in the test slips. According to the angle in which the person loses grip, the classification coefficient “A/B/C” is determined on a continuum of 3 intervals: A (gradients up to 12°), B (gradients up to 18°) and C (gradients up to 24°).
