INDOOR SPORTS FLOOR
SKID RESISTANCE: SRT NEN-EN 13036-4
INDEPENDENT – RELIABLE – EXPERT
The Dutch Floor Testing Company conducts surface roughness measurements or slip resistance measurements of among other things indoor and outdoor sports floors by means of the SRT-method.
Floors may cause nasty falls, accidents or slips with far-reaching medical and financial consequences.  
Often this is due to the fact that the floors are too slippery and/or they are soiled. 
If you suspect that your floor is not safe, or if you want to be absolutely certain that your floor is safe enough: 
The Dutch Floor Testing Company measures the surface roughness or slip resistance of almost all floors. 
 
Measuring method: SRT NEN-EN 13036-4 
Measuring instrument: Pendulum Skid Resistance Tester (SRT tester). 
Slider: CEN 
Measuring conditions: dry indoor sports floor  
Measuring conditions: dry and wet outdoor sports floor
At each location, the instrument is checked by means of a zero measurement, and adjusted. Several measurements are carried out. As soon as the measured values are relatively constant, 5 measured values are recorded. In addition, the temperature and the type of surface are recorded.  
The average of the 5 measured values is the measured value.
Testing:
NEN-EN 14877 synthetic outdoor floors slip resistance requirement
Dry: 80 – 110
Wet: 55 – 110
NEN-EN 14904_2006: indoor sports floors slip resistance requirement:  
Dry: 80 – 110 
Dry: 80 – 115 (future NEN-EN 14904-1_2017 Draft) 
Certificate: 
If the floor meets the slip resistance requirements, a certificate will be issued. This certificate will be valid for a maximum of 12 months.
