Epoxy Coating Slip Resistance Testing: 12 Products, One Manufacturer, 5 Failures
A manufacturer submitted 12 epoxy, polyurethane, and polyaspartic floor coatings for ANSI A326.3 and pendulum testing. Five failed every category.

Aquatic Play Equipment Slip Resistance Testing: What ASTM F2461-26 Requires
ASTM F2461-26 now requires wet, barefoot pendulum testing for aquatic play equipment, matched to AS 4586’s P4 mark. What it means for South Florida facilities.

Documented Slip Testing: The Evidence That Actually Proves Due Diligence
Why a documented, dated slip testing program is real evidence of due diligence in a slip-and-fall claim, and why a late or mismatched test can fail you.

35 and 45: The Closest Thing America Has to Pendulum Guidance
ASTM E303-22 tells you how to run a pendulum. It does not tell you what the number should be. One American organization answered that question, and it did so in 2002. The Ceramic Tile Institute of America endorsed the pendulum, set minimum BPN values for wet floors, and said that where the pendulum and a drag instrument disagree in litigation, the pendulum takes precedence.

A Steel Sled on a Stage Floor: What ANSI E1.34 Measures, and What It Leaves Out
ANSI E1.34-2009 (R2024) is the American standard for measuring how slippery a performance floor is. Having read the clauses rather than the abstract, the surprise is how much it gets right. The gaps are elsewhere, and they are large. There is no contaminant procedure of any kind, there are no acceptance criteria whatsoever, and the standard’s own text says its headline number is for marketing.

What Is a Good DCOF Rating? The Real History Behind the 0.50 Number
The 0.50 SCOF number traces to a 1945 lab memo on dry polish, not wet floors. Here is what a good DCOF rating means for a floor today.

The Tile Is Not the Floor: What ANSI A326.3 Can and Cannot Tell You About a Floor in Service
Grant Davidson at IPA Laboratories has published a two-part series on DCOF and the ANSI A326.3 product use classification. Both parts are correct. Read together they draw a boundary neither part draws on its own. The classification compares products under one standardized contaminant, forecast against a building that does not exist yet, and nothing downstream checks whether the forecast held.

DCOF vs. Pendulum Test: How ANSI A326.3 and ASTM E303 Work Together
DCOF (ANSI A326.3) and pendulum (ASTM E303) test slip resistance differently, not competitively. Here’s what each measures and why facilities use both.

Hospital Floor Slip Resistance: One Lobby, Two Tests, Two Different Answers
A hospital lobby floor passed DCOF testing at two of three spots but failed pendulum testing at all three. Here’s what that gap means.

The Spec Said Slip Resistant. Nobody Measured It.
Florida’s code tells you a pool deck must be slip resistant and then defines that as a textured surface. It gives you an adjective, not a number. Not measuring does not make the number go away. It means someone else picks it three years later, with a tribometer, after a fall. Here is what Florida law does to a GC and a sub when that happens.
