Laboratory and Field Floor Slip Resistance (Coefficient of Friction/DCOF Rating) Testing Services
Safety Direct America provides laboratory and field floor slip resistance testing services all over the USA and beyond. Our flooring slip coefficient testing expertise is unmatched in the Americas. We provide specialized, certified, engineer-stamped floor and tile dynamic coefficient of friction testing (DCOF rating), ASTM E303-93 road skid resistance testing, SCOF tile testing (ASTM C1028 and ANSI B101.1 – reliable in dry condition only), Sustainable Slip Resistance floor testing services, and we also sell floor slip test instruments (such as the BOT-3000E). Quick DCOF tile rating turn-around in 2-3 days! We’re the tile slip coefficient testing experts! Get a COF tile rating before installation and eliminate slips. Call us at 800-988-6721 to request a quote or with any questions regarding field testing.
![]() | ANSI A137.1/A326.3 (aka BOT-3000E “DCOF AcuTest”) PLUS a Pendulum DCOF slip test: $387.00 per sample. This package will give you two separate reports – one for 2012 IBC requirements (DCOF Rating) and another for the slip test we recommend the most. |
![]() | 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 (COF) Lab Test | Charge per Sample | Why do this test? | Comment |
ANSI A137.1 (aka “DCOF AcuTest”) DCOF Rating Test or ANSI A326.3 | $200 | Specified in 2012 International Building Code for indoor wet areas. Uses BOT-3000E Tribometer. “DCOF AcuTest” | Requires a 0.42 minimum “passing” DCOF for indoor level floors. Latest version gives min. for other areas too |
Pendulum DCOF Test (HB 198/AS 4586 or 4663-2013, EN 13036-4, BS EN 16165, 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. Based on 50 years of real-world research in 50 nations |
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. |
ANSI B101.3 DCOF Test | $200 | An expired U.S. standard using the BOT-3000E tribometer, mostly indoors. We recommend using A326.3 instead | Pendulum is much better for assessing safety because of the decades of research behind it |
ASTM C 1028-07 SCOF Test | $290 | Some specifiers still require it | Obsolete, misleading test withdrawn by ASTM in 2014. Not valid for assessing pedestrian safety |
ASTM E 303-93 Road Skid Test | $230 | An American skid test for road surfaces. Also used for floors | A simplified wet pendulum test with soft TRL rubber. |
ANSI B101.1 SCOF Test | $200 | If required by specifier. Not a valid test for pedestrian safety, because it’s a static (SCOF) test | This is an expired test that can be helpful for dry areas only |
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 |
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 for a DCOF rating at your location, the charge may 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 – 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)933-6971.
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 $75 (expediting fee per test). Pay that fee here by entering “75” (per test) above the yellow “Pay Now” button. Test samples are stored for 21 days before being discarded. If you’d like YOUR 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. You can include a return shipping label with your shipment, which will help keep this charge low. | ↓ Video on floor slip resistance testing ↓ |
