When a slip-and-fall claim lands on a property manager’s desk, the first question an attorney asks is simple: what was the measured slip resistance of that floor, and who measured it? If the answer is a guess, a product brochure or nothing at all, the property is exposed. This is why defensible friction data matters, and why the two services behind it, CATL lab testing and tribometer rental, are worth understanding before you need them.
What CATL is
CATL, the Consumer Assurance Testing Lab, is an independent slip-resistance test lab practicing to ISO/IEC 17025:2017. It is equipped to test the slip resistance of flooring and floor care products to the nationally and internationally recognized standards, including ANSI A326.3, ASTM E303, ASTM F2913, DIN 51130 and DIN EN 16165. CATL is a research partner of the University of North Texas College of Engineering and is represented exclusively by Walkway Management Group.
Architects and specifiers submit flooring products to CATL for pre-project approval. Manufacturers use it for product certification. Attorneys and insurers rely on its findings in forensic investigations and litigation. In every case the purpose is the same: a clean, repeatable, documented number that holds up when someone challenges it.
When lab testing is the right tool
Lab testing measures a sample of flooring under controlled conditions. It is the right approach when you are:
- Specifying a new floor and want proof before purchase that the product meets the slip-resistance value the project requires.
- Comparing products on equal terms, using one method and one instrument, instead of trusting each manufacturer’s literature.
- Testing a floor care product, such as a cleaner, sealer or finish, to see what it does to traction before it goes down across a whole building.
- Documenting the as-installed condition of a surface before it goes into service, so there is a baseline on file.
The current reference for most commercial interiors is ANSI A326.3, which defines how wet dynamic coefficient of friction (DCOF) is measured and the values a surface is expected to meet for its intended use. For level interior floors expected to be walked on when wet, the commonly cited threshold is a wet DCOF of 0.42.
What tribometer testing in the field adds
A tribometer is the instrument that performs the measurement. The BOT-3000E is the digital tribometer most widely used for ANSI A326.3 work, and it can be used in the lab or carried into the field. Field testing matters because a floor’s real-world slip resistance is not the same as the sample’s. Sealers, cleaning chemicals, dwell time, rinsing, wear patterns, standing water and years of foot traffic all change the surface. A tile that tested well in a lab five years ago may sit well below the threshold today, and only an on-site measurement will show it.
That is the distinction that protects a property. Lab testing tells you what a material can do. Field testing tells you what your floor is actually doing right now, under the conditions people walk on it.
Rent the tribometer, or have the testing done
Facility teams that run a regular slip-resistance program sometimes rent a tribometer and take routine measurements themselves. That works with one condition: the person operating it has to know the ANSI test method thoroughly and document every step, because a measurement that was not performed and recorded correctly is worthless the moment it is challenged. The instrument is only half the job. The method and the documentation are the other half.
Walkway Management Group rents the BOT-3000E, trains teams to use it correctly through its BOT-3000E training course, and performs field testing directly at sites across the country. For many clients the right answer is a combination: Walkway runs the baseline audit, and the facility team handles routine checks between formal audits using the same instrument and method, so every number on file is comparable.
How often to test
A single test is a snapshot. Slip resistance changes with cleaning practice and wear, so the value of a program comes from repetition. As a practical guide, production and high-traffic areas are worth retesting at least quarterly, with high-risk zones such as entrances, wet process areas and food service tested monthly. Office areas can usually be retested annually. Any change in floor care chemistry, a renovation or a near-miss is a reason to test again immediately rather than wait for the schedule.
What defensible documentation looks like
Whether the testing happens in the CATL lab or in your building, the record that actually protects a property has the same elements:
- The test method cited by name and version, for example ANSI A326.3.
- The instrument used and its calibration status.
- The measured DCOF values by location, under the specified wet condition.
- The date, the operator and the surface condition at the time of the test.
- Any corrective action taken, and the retest result that confirms it worked.
That record is what turns a slip-resistance number into evidence. It is the difference between telling a court you believed the floor was safe and showing a court that you measured it, documented it and acted on it.
Where to start
If you are specifying a new floor, evaluating a product, changing your cleaning program or responding to a near-miss or a claim, start with the right instrument and the right method. Walkway Management Group provides CATL lab testing, BOT-3000E tribometer rental and training, and full on-site field audits for architects, property managers, facility teams and the attorneys who advise them. The goal is the same in every case: measured, documented, defensible slip-resistance data, before an incident rather than after one.
