Appendix P

EN ISO 10545-5: Determination of impact resistance by measurement of the coefficient of restitution: This test is only applied on tiles to be used in areas

where the impact resistance is of particular interest. The normal requirement for light uses is a restitution coefficient of 0,55. Higher values would be asked for heavy

uses.

EN ISO 10545-14: Determination of resistance to stains: The test is compulsory for glazed tiles. If stains may be a problem for unglazed tiles please refer to the

manufacturer. This test is not to be used for the temporary colour variations which may appear in certain types of glazed tiles because of the water absorbtion of the

body under the glaze.

Appendix N

Classification of glazed floor tiles based on resistance to abrasion:

This approximate classification is to be intended as a guide (see ISO 10545-7). It should not be used for product prescriptions related to specific requirements.

Class 0:

Class 1:

Class 2:

Class 3:

Class 4:

Class 5:

Tiles in this class are not recommended for floor coverings.

Floor coverings in barefoot areas or with use of shoes with soft soles without abrasive dirt (for example bathrooms and bedrooms in residential buildings,

without directaccess from outside).

Floor coverings in areas where using shoes with soft or normal soles and with eventual small quantities of abrasive dirt (for example the day-rooms in

private houses except kitchens, entrances and other rooms with high traffic). This is not valid for not normal footwear, as for example hobnail shoes.

Floor coverings in areas where using normal shoes with frequent presence of small quantities of abrasive dirt (for example kitchens in residential buildings,

living rooms, entrances, balconies, verandah and terraces). This is not valid for not normal footwear, as for example hobnail shoes.

Floor coverings in ordinary traffic areas with abrasive dirt, therefore with worst conditions than in Class 3 (for example entrances, commercial kitchens,

hotel, shops and selling areas)

Floor coverings in areas with high pedestrian traffic for extended times and with abrasive dirt, so that the conditions are the worst where you can use

glazed floor tiles (for example public areas like commercial centers, airport halls, hotel entrances, public pedestrian crossings ad industrial applications).

This classification is valid for applications in standard conditions. Shoes, type of traffic and foreseeable cleaning systems should be taken in consideration and the

floors should properly be protected from abrasive dirt at the building entrances through shoes cleaning systems. In extreme situations of very heavy traffic and lot of

abrasive dirt, unglazed floor tiles of Group I can be taken in consideration.
