Wet DCOF Ratings

Dynamic coefficient of friction (DCOF) ratings help designers, architects, and builders make more informed choices on tile flooring.

Friction is the innate force that resists the sliding motion of one surface against another, such as the motion of a foot against a tile floor. Contaminants, such as liquids, oil, dirt, and debris, can alter that innate friction of a surface. So, commercial and residential builders need to choose appropriate flooring products that will reduce the risk of slips, trips, and falls. That's where a DCOF rating comes into play.

The DCOF AcuTest™ uses a portable robot (the BOT 3000), an SBR rubber sensor, and slightly soapy water (0.05% sodium lauryl sulfate solution) to measure dynamic friction. It’s a repeatable, reproducible method for measuring DCOF and, according to the TCNA, it is a major improvement over the old test method. It also offers a standardized minimum threshold, which is new to the industry.

For more information on DCOF, visit TCNA.

Crossville adheres to wet DCOF AcuTest™ to better support tile selections.

It’s important to note that not all products with a DCOF value over the 0.42 standard are suitable for all applications. Type of use, expected traffic and wear, contaminants, maintenance, and manufacturer guidelines must also be considered when specifying a product.

  1. DCOF AcuTest™ uses slightly soapy water instead of clean water for testing.
  2. The new 0.42 DCOF rating is the benchmark for interior level flooring to be walked upon when wet.
  3. The DCOF AcuTest™ is included in the latest version of ANSI A137.1 Specifications for Ceramic Tile.
  4. All Crossville flooring products have been tested using the DCOF AcuTest™ method.
  5. Crossville produces mosaic tiles with the Cross-Sheen finish. The AcuTest™ Wet Dynamic COF is > 0.42. Their small sizes ensure frequent grout joints which provides traction and draininage. Crossville cannot control situations involving incorrect installation, improper slope to the drain for elimination of standing water, and poor surface cleaning. This information is provided so that customers may make a realistic and informed decision when comparing Crossville's mosaic to other tile products in wet area environments, such as residential/commercial bathrooms, showers, and interior pool ecks.
