Both R10 and 36+ are slip resistance ratings measured ‘ex-factory’ or ‘out of the box’, which means the performance is stated at the point of purchase only. Many standard LVT products will achieve R10 or 36+ when they leave the factory, but a floor can only be classed as a safety floor if it achieves the BS EN 13845 Enhanced Slip Standard which is measured through abrasion testing. The number of slip resistant particles in a defined area on the surface of a product are counted, then at each stage of 10,000 cycles of abrasion, the product must have lost no more than 10% of the original slip resistant particles. This performance is reported as the usage classification, and both Amtico Signature and Spacia 36+ perform at the highest level of 50,000 cycles making them suitable for Commercial Very Heavy and Light Industrial Heavy use.
