International Stoneworks, Inc. now offers SLIP RESISTANCE TESTING of floors with the most advanced filed equipment in the market: the BOT-3000.
The BOT-3000 (Binary Output Tribometer) measures both static and dynamic COF (Coefficient of Friction) performs the following tests:
Dry Static
Wet Static
Dry Dynamic
Wet Dynamic

While static COF is a measurement of the force required to move a stationary object into motion, dynamic COF is a measurement of the resistance generated from a moving object coming into contact with an object at rest.

Dry testing results are based on ASTM (American National Standards Institute)
D-2047 slip-resistance standard
Wet testing results are based on NFSI (National Floor Safety Institute) standard

THE MARBLE INSTITUTE OF AMERICA (MIA), THE COUNCIL OF NORTH AMERICA (TCNA), THE CERAMIC TILE DISTRIBUTORS ASSOCIATE (CTDA) AND THE AMERICAN INSTITURE OF ARCHITECTS (AIA) DO NOT MAKE SPECIFIC RECOMMENDATIONS AS TO WHAT AN ACCEPTABLE CORFFICTENT OF FRICTION SHOULD BE.
THE OCCUPATIONAL HEALTH AND SAFETY ADMINISTRATION (OSHA) DOES NOT MANDATE A PARTICULAR COF FOR WALKING/WORKING SURFACES, ALTHOUGH THEY DO MAKE A RECOMMENDATION THAT A WALKING SURFACE IN THE WORKPLACE SHOULD HAVE A COF OF 0.50 OR GREATER ON THE ASTM TEST. THIS IS ONLY A RECOMMENDATION AND NOT A REQUIREMENT

1. Initial testing (after installation)
2. Periodic testing (monthly, quarterly, semi-annually or annually)
