|ANSI A137.1 (aka DCOF AcuTest) PLUS a Pendulum DCOF slip test: $387.00 per sample. This package will give you two separate reports – one for IBC requirements (DCOF A137.1) and another for the slip test we highly recommend the most. We also offer:|
|Floor Slip Resistance (COF) Lab Test
||Charge per Sample
||Why do this test?
|ANSI A137.1 (aka “AcuTest”) DCOF Test or ANSI A326.3||$200||Specified in 2012 International Building Code for indoor wet areas.||Similar to ANSI B101.3. Requires a 0.42 minimum “passing” value and more stringent sensor prep.|
|ANSI B101.1 SCOF Test||$200||If required by specifier. Not a valid test for pedestrian safety, because it’s a static test.||Made obsolete by ANSI B101.3, a dynamic test.|
|ANSI B101.3 DCOF Test||$200||A recent U.S. standard using the BOT-3000E digital tribometer, mostly indoors. Based on slip and fall research.||Pendulum is more appropriate for outdoor surfaces because of its higher speed.|
|ASTM C 1028-07 SCOF Test||$230||Some specifiers still require it.||Obsolete, misleading test withdrawn by ASTM in 2014. Not valid for assessing pedestrian safety.|
|ASTM E 303 Road Skid Test||$230||An American skid test for road surfaces.||A simplified pendulum test with soft TRL rubber.|
|Pendulum DCOF Test (CTIOA, HB 198/AS 4663-2013, EN 13036-4, TS 15676, EN 14231, etc.)||$230||Dry and wet slip resistance appropriate to various conditions, e.g. pool deck, lobby, rest room, etc.||The most widely used slip resistance tests worldwide. Endorsed by CTIOA since 2001.|
|SlipAlert DCOF Test||On-site only||Qualitative demonstration that in some cases mimics pendulum readings.||A simple, durable machine is used that requires minimal training.|
|Sustainable Slip Resistance Pendulum DCOF Test||$320||Check whether slip resistance survives after significant abrasive wear by pedestrians.||For areas with high pedestrian traffic that must remain slip resistant.|
|Tortus Floor Friction Digital Tribometer DCOF Test||$230||Dry and wet slip resistance up to high values of coefficient of friction with hard or soft rubber.||Endorsed by Ceramic Tile Institute of America since 2001.|

To have your floor slip resistance tested at your location, the charge is based on time and expenses. We are certified by the City of Los Angeles (one of the few government agencies in the USA that has an approval process – look here under Sotter Engineering) for testing the slip resistance of flooring, and floor slip test reports come stamped by a registered professional engineer, usually within 3 business days of receiving your lab sample. Sample size requirements are discussed below. The total charge (e.g. $200) is the same for testing either one, two or three identical pieces. For more info, contact us by email or call (949)582-0889.
|If MULTIPLE TESTS are ordered on one sample at the same time, a 10% discount applies to the test total charge. If ten or more tests are ordered and paid for in the same calendar year, every tenth test will be at no charge. TURNAROUND TIME for laboratory slip resistance tests is usually 2-3 business days. RUSH FEE: If you need your floor slip testing expedited in a rush, we can usually get your flooring tested and a report sent to you within one business day (with rare exceptions) of receiving your sample for an extra $50 (per test). Test samples are stored for 21 days before being discarded. If you’d like them returned, please let us know promptly. In most cases, there is a $15 fee (plus the cost of shipping if you don’t have an account number we can use) for the return of samples. This charge could be more based on individual circumstances.||

Dynamic Coefficient of Friction (DCOF):
We can run slip resistance tests using these four test methods and instruments, all of which measure dynamic coefficient of friction:
- BOT-3000E Binary Output Tribometer with Neolite, SBR, Four S, TRL, leather or hosiery sliders. Can measure COF up to 1.00. We can test using the ANSI B101.3 (dynamic coefficient of friction) and ANSI B101.1 (static coefficient of friction – SCOF) methods with the BOT-3000E, as well as the new ANSI A137.1 (or ANSI A326.3) dynamic coefficient of friction (DCOF) AcuTestSM that is now part of the current International Building Code.
- British Pendulum DCOF test (adapted for floors from ASTM Method E 303) with Four-S and/or TRL rubber slider; and EN 13036-4 with CEN rubber slider. The British pendulum is used for our highly recommended Sustainable Slip Resistance test. We can also run an ASTM E-303 test for road skid resistance with the British Pendulum.
- Tortus Floor Friction Tester Digital Tribometer with Four-S (hard) and/or TRL (soft) rubber slider
- SlipAlert floor slipperiness indicator
Peak-to-valley surface roughness:
- Taylor-Hobson Surtronic 10 profilometer
Static Coefficient of Friction (SCOF):
Horizontal dynamometer pull-meter (ASTM C1028-07): Laboratory floor slip-resistance tests for SCOF includes a written report signed and stamped by a California-licensed Professional Engineer. We conduct this test but do not offer the apparatus for sale. ASTM, Ceramic Tile Institute of America, Tile Council of North America, University of California Medical Center and Safety Direct America do NOT recommend this method (or any wet static coefficient of friction test) as a primary means of assessing floor slip resistance. [ASTM standards rules allow only test devices that do not involve patented or proprietary technology. For this reason the best test methods for floor friction, except for the pendulum and the BOT-3000E, are not and can not be specified by ASTM standards.] We can also run the ANSI B101.1 static SCOF test, if required. Field slip resistance test prices are based on time and travel expenses for our technician. Contact us for a quote by email or call 1-800-988-6721.
We presently do (or have recently done) floor slip resistance testing both on-site and/or in our laboratory for two major cruise ship companies, Outrigger Reef on the Beach in Waikiki, Exeter Hospital in New Hampshire, the Ceramic Tile Institute of America, attorneys representing both plaintiffs and defendants, the Cities of New York, San Francisco, Palo Alto and Los Angeles, Cartier, The Montage Resort and Spa, Crowne Plaza Hotels, Intel, Ceramic Tile and Stone Consultants, and many other major international companies all over the USA and beyond.
Ceramic Tile Institute of America endorses the Tortus and the Pendulum. In a study of nine types of tribometers at the University of Southern California Medical Center in which slip-and-fall experts from around the world participated, the Tortus received the highest rating; click here for details on the slip-tester test. SlipAlert has had very favorable reviews from British and Australian government safety research agencies. The static coefficient of friction method ASTM C1028 is principally used for manufacturing quality control purposes rather than assessing slip resistance, but is sometimes specified as an indicator of slip resistance. We recommend using the Tortus or pendulum slip resistance test instead, as these are more reliable and are recommended for slip resistance testing by Ceramic Tile Institute of America. We also recommend the BOT-3000E as it has an ANSI test method (B101.3 dynamic coefficient of friction test) and safety standards for wet slip resistance testing.
