If the floor is likely to be lubricated with water or grease in use, it needs to coefficient of friction lab report anti-slip under these expected conditions. Floor slip resistance testing can be carried out dry, wet with water, or lubricated with oils and other contaminants. The United Kingdom has since 1971 had well-established slip resistance standards based on the pendulum. This test was developed for pedestrian traction by the U.
National Bureau of Standards in the 1940s and further refined in the UK. Pendulum Test Slip Resistance Values for many different situations: e. The Tortus digital tribometer slip resistance test method is based on a proprietary or patented device, which makes it ineligible to become an ASTM standard. It is produced in the U. The Tortus is now the primary instrument for assessing dry slip resistance in the latest Australian slip test standard — AS4586-2013. 2001, with the pendulum being the primary standard. The BOT-3000 is a drag-sled meter, which means that it crawls along the floor under its own power at a constant speed measuring the resistance to slip of a standardized piece of rubber loaded into the bottom of the machine.
The BOT-3000 performs a test without human input except for the pressing of a button, making it more difficult for the operator to manipulate the results of the test. The BOT-3000 is no longer being manufactured or serviced by the manufacturer. 2011 and is similar to the original BOT-3000. The Variable-Angle Ramp is a German-developed method for obtaining pedestrian slip resistance values. Flooring samples are mounted horizontally on the ramp tester and an operator clad in safety boots or bare feet performs a standardized walk up and down the sample while wearing a harness to stop the operator from being injured.
The sample is slowly inclined until the operator slips on the surface. The angle at which the subject slips is then recorded. Over 150 safety criteria have been adopted in Germany and Australia for specific situations — swimming pool decks, commercial kitchens, restrooms, etc. Manufactured in the United Kingdom, it is used for field testing, but is of limited use in a laboratory setting because it requires a long path length of flooring to conduct tests.
The 2012 International Building Code does not strictly adopt ANSI A137. 1 with respect to floor surface testing. That is why the ASTM C1028 test method was officially withdrawn with no replacement in 2014. See «external links» at the bottom of this page for more information on the inadequacies of the C1028 test.
Shortly after being published in 2004, ASTM withdrew these standards in 2006, with no replacement. They are still available for purchase from ASTM as a withdrawn or «historical» standard.
