Polished Floors Are Slippery When Wet – No Matter What Your American-Made Slip Resistance Test Device Says!

Reliable floor slip resistance test devices include the pendulum floor slip resistance tester and the SlipAlert Tribometer (now known as the iAlert), which both measure the dynamic coefficient of friction (DCOF) of floors. In the United States of America, we have in the past (and present) allowed tile manufacturers and people who make their living … Continue reading “Polished Floors Are Slippery When Wet – No Matter What Your American-Made Slip Resistance Test Device Says!”

Abandoned, Withdrawn and Flawed Floor Slip Resistance Test Methods Continue to Plague the USA

Slip and fall accidents can have serious consequences, leading to injuries and even fatalities. That’s why it’s crucial to ensure the safety of floors, particularly in public areas such as shopping centers, hotels, and hospitals. However, not all floor slip resistance testing techniques are created equal, and some American tests have even been withdrawn or … Continue reading “Abandoned, Withdrawn and Flawed Floor Slip Resistance Test Methods Continue to Plague the USA”

Fool Me Once: The Floor Slip Resistance Testing Misinformation Campaign Fooling the USA

We’ve all heard the old adage, “Fool me once, shame on you; fool me twice, shame on me.” The Tile Council of North America (TCNA), who reportedly is “in partnership” with at least one of America’s largest tile manufacturers, spent almost two decades promoting the misinformation that the ASTM C1028 static coefficient of friction (SCOF) … Continue reading “Fool Me Once: The Floor Slip Resistance Testing Misinformation Campaign Fooling the USA”

How to Get The Slip and Fall “Expert” Witness Testimony from an English XL VIT and Brungraber Mark IIIB User Thrown Out of Court

Slip and fall “expert” witnesses in the United States typically use either the English XL Variable Incidence Tribometer (VIT) or the Brungraber Mark IIIB, which is incredibly frightening considering that neither of these two instruments have a published, peer-reviewed test method in any country on earth, and both (the English XL and Brungraber Mark II, … Continue reading “How to Get The Slip and Fall “Expert” Witness Testimony from an English XL VIT and Brungraber Mark IIIB User Thrown Out of Court”

Pool Deck Slip Standard would Create Jobs for Lawyers and Emergency Room Doctors

A swimming pool deck slip resistance standard is proposed that if adopted will cause hundreds of millions of dollars of misspent investment; lead to thousands of slip and fall accidents, many with life-changing injuries; cost hundreds of millions in medical bills and other losses; and lead to far too many premature deaths due to injuries … Continue reading “Pool Deck Slip Standard would Create Jobs for Lawyers and Emergency Room Doctors”

2022 Revised ANSI A326.3 Has Five Situation-Specific DCOF Minimums — And Crucial Caveats

In February of 2022, the American National Standards Institute (ANSI) issued a revised version of their “Test Method for Measuring Dynamic Coefficient of Friction of Hard Surface Flooring Materials.” The test method is called ANSI A326.3, and it sets a very low bar for DCOF in various flooring areas. Slip and fall accidents will likely … Continue reading “2022 Revised ANSI A326.3 Has Five Situation-Specific DCOF Minimums — And Crucial Caveats”

BOT-3000E Manufacturer Advises Against Using ANSI/NFSI B101.3 and B101.1 to Assess Floor Slip Resistance

The manufacturer of the BOT-3000E digital tribometer is Regan Scientific Instruments of Carrollton (Dallas), Texas. Recently we asked Regan for an update on ANSI B101.3, “Test Method for Measuring Wet DCOF of Common Hard-Surface Floor Materials,” approved January 18, 2012, and ANSI/NFSI B101.1. We received a reply from Peter Ermish, President. Here’s part of his … Continue reading “BOT-3000E Manufacturer Advises Against Using ANSI/NFSI B101.3 and B101.1 to Assess Floor Slip Resistance”

Many Polished Concrete Floors are Slippery when Wet

Can polished concrete floors be slippery when wet? Several web sites say yes, but others (mostly polished concrete vendors) say no, it only looks that way. A study of polished concrete published by the American Society of Concrete Contractors (ASCC) in Concrete International shows wet dynamic coefficients of friction (DCOF) as measured by ANSI A137.1 … Continue reading “Many Polished Concrete Floors are Slippery when Wet”

A Review of Standards for Pedestrian Slip Resistance Testing

There are a number of floor slip test methods established by standards-setting organizations that assess pedestrian slip resistance. Here we’ll review the most widely known and current ones. They are distinguished by the devices used in the testing. Terms such as DCOF rating, coefficient of friction, slip coefficient, slip resistance rating, and friction coefficient all … Continue reading “A Review of Standards for Pedestrian Slip Resistance Testing”

How does ANSI DCOF compare with Pendulum Test Value?

The most recent American National Standards Institute (ANSI) dynamic coefficient of friction (DCOF) test method, ANSI A326.3, states that “hard surface flooring materials suitable for level interior spaces expected to be walked upon when wet with water shall have a wet DCOF of 0.42 or greater when tested … as per this standard.” The older … Continue reading “How does ANSI DCOF compare with Pendulum Test Value?”
