Floor Slip Resistance Testing Services
Certified Coefficient of Friction (COF) Testing for Roads and Floors, in the Laboratory and the Field
Safety Direct America/Sotter Engineering provides laboratory and field independent third-party floor slip resistance testing and road skid resistance testing services all over the USA and beyond. Our floor friction slip coefficient testing expertise is unmatched in the Americas, and our integrity is untouchable. We provide specialized, certified, engineer-stamped floor, tile, and roadway dynamic coefficient of friction (DCOF) testing, ASTM E303-22 road and floor slip resistance testing, SCOF tile testing (ASTM C1028 and ANSI B101.1 – reliable in dry condition only), and we also sell floor floor friction test instruments (such as the pendulum DCOF tester and SlipAlert). Quick COF tile slip test turn-around in about 3 days! We’re the tile slip coefficient testing experts! Get a COF tile test before installation and eliminate slips. Call or email John at 949-933-6971 to request a quote for field floor slip resistance testing, or with questions regarding floor slip resistance test standards.
Lab Floor Slip Resistance Testing Services
ANSI A326.3 and an ASTM E303-22 Pendulum DCOF slip test: $387.00 per sample. This lab slip resistance test package will give you two separate floor DCOF test reports – one for the latest test method written for the BOT-3000E (ANSI A326.3), which sets a very low bar, and another for the latest American floor slip resistance test (the newly revised ASTM E303-22 pendulum test), which we recommend the most for assessing the real-world safety of floors based on 50 years of peer-reviewed, international research in at least 50 nations.
OR, get the above tests PLUS our Sustainable Slip Resistance (wear) Test, which will give an indication of the slip resistance of your flooring after 1-2 years of use in a busy environment with lots of foot traffic. This is our most highly recommended option. $457.00 per sample.
Floor Slip Resistance Tests
ASTM E 303-22 Floor Slip Resistance Test or Road Skid Resistance Test – $230
Best dynamic coefficient of friction (DCOF) floor slip resistance test for measuring real-world coefficient of friction of both floors and the skid resistance of roads. Uses the pendulum tester, which has a published test method in over 50 nations. Th3 ASTM E303-93 (2022) test was newly-revised in 2022. Safety criteria is based on 50 years of international research into real-world slip and falls. Our most recommended floor slip test method for reliable data.
According to the test method, this test is for “comparing surfaces”, not assessing slip risk. DCOF safety suggestions in this test method are easy to pass and written by people interested in helping sell slippery tile. Requires a 0.42 minimum DCOF for indoor level floors. Latest version gives minimums for other areas, too. Can give “passing” grades to very slippery floors. Do not rely solely on this test to assess safety.
Pendulum DCOF Test (Australia’s HB198, AS4586, AS4663, or Europe’s BS EN16165 or EN13036-4) – $230
Pendulum floor slip resistance testing using international standards such as the European pendulum test method, Australian test method, etc. Utilizes the most widely used slip resistance test device (tribometer) worldwide. Based on 50 years of real-world research in 50 nations.
Sustainable Slip Resistance Pendulum DCOF Test – $320
Check whether the slip resistance of your flooring survives after significant wear by pedestrians and maintenance. For areas with high pedestrian traffic that must sustain its slip resistance over time.
ASTM C 1028-07 SCOF Test – $290
Some specifiers still require it, but the results are meaningless in the wet condition. Obsolete, misleading test withdrawn by the ASTM in 2014. Not valid for assessing safety. Measures SCOF, which is irrelevant. Click the “Pay Now” button below to have this floor SCOF slip test done in our lab on your flooring sample.
ANSI B101.3 DCOF Test – $2
An expired U.S. standard using the BOT-3000E tribometer for indoor floors. Use A326.3 instead. The pendulum tribometer is much better for assessing safety because of decades of research behind it. Click the “Pay Now” button below to have this floor friction test done in our lab on your flooring sample.
ANSI B101.1 SCOF Test – $200
We do this floor slip test if required by a specifier, but it’s not a valid test for pedestrian safety, because it’s a static (SCOF) floor slip test. This is an expired test that can be helpful for dry areas only. Click the “Pay Now” button below to have this floor friction test done in our lab on your flooring sample.
SlipAlert DCOF Test – on-site floor slip resistance testing only – call for a quote
Qualitative demonstration that in most cases mimics pendulum readings. A simple, durable machine is used that requires minimal training. Email us to have this test done on your flooring on site. We can also sell you a SlipAlert (also known as iAlert now.)
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. It appears in Australian floor slip resistance test standard. Click the “Pay Now” button below to have this test done in our lab on your flooring sample.

Field Slip Resistance Testing of Floors and Roadway Surfaces
To have slip resistance testing for dynamic coefficient of friction (DCOF rating) at your location, the charge will be based on time and expenses, or may be a fixed price, depending on the situation. We are certified by the City of Los Angeles (one of the few government agencies in the USA that has an approval process) for testing slip resistance of floors and roads, and slip resistance test reports come stamped by a registered professional engineer, usually within 3 business days of receiving your lab sample for slip testing. For more info, contact us by email or call (949)933-6971. Payment for field slip resistance testing (if we’ve already given you the price) can be paid for using the YELLOW “Pay Now” button above.
Sample Size Required For Slip Resistance Tests
Ideally, you will send a floor, tub or roadway sample 12″x12″ for slip resistance testing, but most slip tests can be done on smaller samples (for instance, a minimum of 5″x7″ for pendulum slip resistance tests, although bigger is better). Some test methods (ANSI A326.3, ASTM C1028-07) ask for three identical samples, but all tests can be done on one sample, if necessary. All tests above are done in the wet and the dry condition, except A326.3, A1371.1, and B101.3…those test methods only call for wet testing (although we can do dry ANSI A326.3 dry testing for an extra $50 – pay using yellow “Pay Now” button above.) Here are some sample test reports: ASTM E303 Pendulum Slip Resistance Test Report, ANSI A137.1/A326.3, and Sustainable Slip Resistance (SSR) Pendulum Test. Using decades of research from around the world, we can now use ASTM E303-22 pendulum test results to assess real-world slip resistance using the safety criteria used in the United Kingdom, Europe, Australia, New Zealand, and elsewhere.
Rush Fee and Other Common Slip Resistance Test Questions
RUSH/EXPEDITE: If you need your floor slip resistance tests expedited, we can usually get your flooring or roadway surface tested and a report sent to you within one business day (with rare exceptions) of receiving your sample for an extra $75 (expediting fee per test). Pay that fee here by entering “75” (per test) above the yellow “Pay Now” button. Contact us by email to make sure that we’ll be able to handle your request.
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 around 3 business days. Test samples are stored for 21 days before being discarded. If you’d like YOUR slip resistance test SAMPLES RETURNED, please let us know promptly. There is minimum of a $25 fee (plus the cost of shipping if you don’t have an account number we can use) for the return of a sample. This charge could be more based on individual circumstances. Preferably, you can include a return shipping label with your shipment to us, which will help keep this charge low.
