Individual steps for monitoring and preventive control of changes to the surface of
floor coverings
6.4.1 Newly installed floor coverings
Reference measurements should be performed for newly installed floor coverings prior to the building site clean-up. The first control measurement should be performed after the building site clean-up in order to identify possible changes to the surface (see Fig. 1).
Additional control measurements are carried out at regular intervals to analyse the anti-slip properties over the service life (monitoring).
Further measures are to be considered if the determined values deviate by more than 10 %.
6.4.2 Evaluation of floor coverings already in use
If reference measurement values are not available, the following procedure is recommended:
Comparative data should be collected for the floor in use and a reserve sample
Comparative data should be collected for high traffic areas and low traffic areas of the floor in us
The comparative data must be collected under the same testing conditions.
6.4.3 Testing pre- and post-treatment
If any of the following measures are to be taken, comparative data for the flooring should be collected before the beginning and after completion of the measures to determine their effectiveness:
Monitoring and optimising cleaning procedures
Chemical treatment of the floor covering such as acid treatments
Mechanical treatment of the floor covering such as sanding, blasting, etc.
Application of a coating/seal
The data are to be collected at the same sites and under the same testing conditions.
