ANSI A326.3/A137.1 Slip Testing

The ANSI A326.3 and A137.1 tile slip test (or “DCOF AcuTest” as it is sometimes called) is performed using the BOT-3000E digital tribometer. This test is primarily a wet test where a 0.42 DCOF rating or greater is considered the minimum for level indoor floors that are expected to get wet in use. The ANSI A137.1/A326.3 tile slip resistance test can be done in the dry condition as well upon request. The A137.1 test was incorporated in the 2012 International Building Code (IBC), and has taken the place of the old ASTM C1028 SCOF test, so building inspectors may require this test. The latest version of A326.3 was published in 2021, and includes minimum DCOF values for areas other than indoor level floors. We do not recommend using ANSI A326.3 to assess the real-world slip resistance of floors, or any other test with the BOT-3000E. The test was created with the help of major American tile manufacturers, and the minimum DCOFs given can give good ratings to very slippery floors.

Recommended Lab Slip Test Package

Option 1: ANSI A326.3 and an ASTM E303-22 Pendulum DCOF slip test: This lab slip resistance test package will give you two separate 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.

Option 2: Two ASTM E303-22 Pendulum DCOF tests — one with each rubber type — one which mimics shoe soles and one mimics bare feet.

Recommended Lab Slip Test Package PLUS Wear Test

Option 3: 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.

If our “Recommended Lab Slip Test Package” doesn’t interest you, we conduct the ANSI A137.1/A326.3 test for “comparing surfaces, not for “assessing safety”. This will cover the wet testing. Dry testing is usually unnecessary since every floor is above a 0.42, so if you’d like to do this test dry, then there will be an additional charge of $125.

Turnaround time for laboratory testing is usually 3 business days. Here is a sample of the report you will receive via email. THREE individual pieces of your flooring are called for in the standard. They should be at least 10″ wide. Your report will be certified and stamped by a registered Professional Engineer. Send your samples (carefully packed) to:
