SCOF vs. DCOF: Choosing the Right Slip Resistance Test Welcome to the slippery world of floor safety, where two acronyms—SCOF and DCOF—have long competed for relevance. At Walkway Management South Florida, we believe it's time to set the record straight and explain which method really protects people (and property) from slip-and-fall incidents. SCOF: The
Tile Council of North America (TCNA) has announced the addition of a five-category “product use classification system” in ANSI A326.3 American National Standard Test Method for Measuring Dynamic Coefficient of Friction of Hard Surface Flooring Materials, published on February 2, 2022.
Most restaurants and businesses have their hired workers clean their floors at the end of the day when everyone is tired and ready to go home. The cleaning usually means that someone takes a dirty mop with some water, that they may or may not have changed out since the previous cleaning, and adds some sort of generic floor cleaner and mops the entire area as fast as they can to finish and go home.
This type of treatment does not leave anything on your tile, it does not create any film that can peel over time. This treatment actually creates a series of microscopic mountain peaks and valleys in your tile.
In the United States, there is only one standard that is acceptable for measuring slip resistance. It is the ANSI A326.3 which tests for the DCOF of a surface and requires the DCOF to measure above a 0.42 to be compliant with the standard.
