Overview of the Skid Resistance Measurement Systems
At present, the following skid resistance measurement systems are recognized, used, and described in the technical specifications in Germany
The Association for quality in skid resistance testing deals with those measurement systems, but it is also open-minded to and interested in new measurement systems.
Admittedly, the measurement system SRM (Stuttgarter Reibungsmesser, Stuttgart friction meter) is defined in a technical specification as well, but it has almost no relevance in practice anymore.
