Onsite Slip Testing VS Lab Slip Testing

In practice, you will always find that there is a discrepancy between the slip resistance testing results that are found in the lab, and those that are found on site. Mostly, it is found that flooring materials or tiles have a lower slip resistance when they have been installed, when compared to that which they had when they were tested in the lab. There are several factors that lend themselves to this discrepancy, such that the results of a wet pendulum test done onsite will be different from that done in the lab. Read more


Micro-roughness measurements and the implications in slip testing

Not many people understand the terms micro-roughness for the floor and how it affects the slippery nature of the surface. Is it possible to use this factor as an indicator of the slip resistance of the floor? According to several experts, the roughness measurement of a floor should not be used for slip testing by itself.

Some years ago, after people started knowing that wet flooring would sometimes give lower slip resistance values with some instruments and not others, the concept of micro-roughness was born. It was thought that this alone would be a quick way of getting to know the slip resistance of a floor. Read more
