Reliable Slip Resistance Test Methods

The pendulum, SlipAlert, Tortus III, and the BOT-3000E (using ANSI test method B101.3) slip test instruments all have official slip resistance test standards based on actual slip and fall research done with them, and are therefore far more reliable methods of testing floor and tile slip resistance than the ANSI A137.1 floor slip test. Safety Direct America can perform the ANSI A137.1 tile slip test, but does not recommend it for assessing safety. Here’s more information on how you can have a slip resistance test (DCOF rating) on your flooring or tile using reliable, highly-researched slip test instruments.

Pendulum slip/skid testerThe pendulum is the slip tester used by 49 nations and it has been endorsed by the Ceramic Tile Institute of America since 2001. Australia, Germany and the United Kingdom have been using this instrument to assess slip and fall risk for several decades now, which makes it the most researched slip resistance test instrument on the planet.

Australia recently published the most sophisticated slip test standard in the world – HB198:2014 – which sets dynamic coefficient of friction (DCOF) guidelines for dozens of different floor situations. It makes sense that an outdoor pool deck might require more slip resistance than a tenth floor elevator lobby, and this test standard differentiates between those situations with different values of required DCOF. Here’s more information on pendulum slip testing in the USA.

BOT-3000 slip testerThe BOT-3000E, used in the ANSI A137.1 slip test method, is also used in ANSI B101.3, which is a test method was based on actual slip and fall research. Using this test method, the BOT-3000 was found to have a 93% correlation to slip tests using the variable-angle ramp. The ramp is considered the gold standard in slip testing, but it has limited use since it is only possible to do the variable-angle ramp test in a lab.

Slip testing using the B101.3 test method can be done by Safety Direct America here in the USA. They also can run the ANSI A137.1 test method. Why would you want to run that test method? Because it is in the 2012 IBC – so you may need a certified report for your records showing that your flooring has passed this minimum requirement.

Tortus 3 Tribometer - slip testerThe Tortus 3 (shown at left) and SlipAlert (shown at right) are also reliable slip test instruments that have current slip test standards in Australia and the United Kingdom, respectively. These instruments can be invaluable since they run tests very quickly on site and can tell a building owner or manager if there are significant differences in slip resistance over various spaces.SlipAlert skid tester

Maintenance issues such as soap residue build-up, and wear issues in high traffic areas can be quickly ascertained by the use of these on-site slip testers. The SlipAlert is of limited use only because it is for on-site slip testing only, but with an official UK standard and lots of real-world research behind it, it is a tool that provide a great deal of information about slip risk in a short amount of time.

Slip resistance test standards in the USA have historically given “passing grades” to almost all types of flooring – slippery when wet or not. Now, thanks to well-researched instruments from Australia, the United Kingdom and Germany, your real-world slip risk can be competently evaluated so that you choose the proper flooring for each particular situation. For reliable slip testing in the USA, visit They also offer remedial solutions for all types of floors and situations, such as anti-slip tape, do-it-yourself non-skid floor coatings, and non-slip floor treatments.
