Anti Slip Grading

Anti Slip floor tiles are given a resistance rating to help grade the non slip level differed by a particular tile. This is known as the "R" value. R13 is the resistance recommended by many professionals for public wet areas such as showers in a changing room. Whereas R9 and R10 values are often used and recommended for domestic Bathroom Tiles or Kitchen Tiles where the risk of slipping is less.

The tile industry refers to the draft informative index (ISO 10545) classification of Ceramic Tiles according to their slip resistance. This classification has been obtained by testing tiles in both wet and dry conditions prior to installation. An understanding of the measurment of the coefficient of friction and the importance of slip resistance for different types of Anti Slip Tiles is essential to avoid and reduce the risk of slip related incidents.

The two Classes within the ISO standard are:
CLASS 1     <0.4     dynamic Coefficient of Friction
CLASS 2     >0.4     dynamic Coefficient of Friction

Further sub divisions can be included:

R9 <0.2 CoF:

Tiles will mostly be smooth glazed tiles which will record this low value when wet. These tiles should only be used in dry situations and should be excluded from wet environments.

R10 >0.2 CoF<0.4 CoF:    

Tiles will usually be glazed tiles which show these values only when wet, although there may also be a small number of unglazed tiles in this category. Besides domestic bathrooms, where the use of a bathmat is essential, they may be sidered for other domestic areas such as kitchens, and other areas which are dry.

R11 + R12 >0.4 CoF<0.7CoF:

Tiles will include some glazed tiles and most unglazed tiles. If a tile has this CoF as a minimum, dry and wet, it may be regarded as safe for installations including bathrooms, kitchens, porches, halls, cloakrooms, and living rooms. They may also be used for public areas such as cloakrooms, lavatories, communal showers,swimming pool surrounds, and larger areas such as shopping centres, airport concourses, hotel foyers, public walkways, etc.
