Understanding Friction Measurements

Coefficient of Friction: (CoF) is a vital safety term, especially when it comes to preventing slip and falls. In simple terms, it's a number that measures how much grip or traction a surface offers. This measurement is key in designing safer spaces, be it in homes, workplaces or other public areas. 

Pendulum Test Value (PTV): This refers to tests that involves a swinging pendulum that simulates a heel strike, the most common cause of slips, to measure the frictional resistance of the surface. The pendulum's foot (usually made of rubber) strikes the surface at a set speed, the resistance is then measured as "PTV".

Measuring the Coefficient of Friction: The CoF is determined by dividing the force needed to slide an object across a surface by the weight of the object. This ratio gives us a number without units, which indicates how slippery or grippy a surface is. Floors with higher CoF values offer better traction reducing the risk of slip and falls. In Floor Safety, there are two ways to measure CoF, one is Static and one is Dynamic (Kinetic).


Static: Measures the amount of force required to initiate movement or cause slipping when a person is standing still on a surface. It is important to note that standards for measuring SCOF have all been withdrawn. 

Dynamic: The dynamic (or kinetic) coefficient of friction (DCOF) is the measure of the resistance to motion between two surfaces that are already in motion relative to each other. In practical terms, it refers to the amount of force needed to keep an object sliding or moving over a surface once it has already started moving. For instance, when considering a person walking, it's the level of resistance they feel underfoot while in motion, impacting their ability to walk without slipping.

Pendulum Test Value vs Coefficient of Friction

Correlation: While both PTV and CoF measure the slip resistance of surfaces, they do so in different ways. PTV is often considered a more realistic measure of slip potential in real-world conditions because it simulates the action of a foot striking a surface.

PTV is often considered a more realistic measure of slip potential in real-world conditions because it simulates the action of a foot striking a surface.

Conversion: There is no direct, universally accepted formula to convert PTV to CoF or vice versa, as they are derived from different testing methodologies. However, both higher PTV and higher CoF values generally indicate better slip resistance.

Usage in Standards: PTV is widely used internationally and nationally and is recognized in various safety standards for assessing floor slipperiness. CoF is also used globally and is featured in many safety standards, but the methods for measuring CoF can vary.

Walmart paid $7.5 Million to man who slipped.

A man named Henry Walker was awarded $7.5 million by a Russell County jury in a lawsuit against Walmart after he fell and broke his hip while reaching for a watermelon in a container in the Phenix City store in 2015. The court found Walmart negligent in maintaining a safe environment and failing to warn the public of potential hazards, leading to a payout of $2.5 million in compensatory damages and $5 million in punitive damages. Walmart plans to appeal the decision.

$10 Million Awarded to Colorado Resident in Walmart Slip & Fall

A Walmart located in Greeley, Colorado, settled a lawsuit with Holly Averyt for slightly over $10 million. Averyt had slipped and fallen on grease outside the store, resulting in significant injuries. Walmart initially denied the spill, but evidence was found by Averyt's lawyers to support her claim. As a result of the fall, Averyt is no longer able to work as a truck driver and experiences ongoing pain and depression. Although her initial award was $15 million, it was reduced to $10 million due to state regulations on the amount of compensation for pain and suffering.

$12.2 Million Paid by Gas Station Convenience Store

A woman slipped and fell while at a gas station convenience store and sustained serious injuries. The awning above the front entrance was leaking and caused a puddle in the walkway. During the fall, the woman hit her chest and chin, resulting in a brain injury and ongoing seizures.

The woman's injuries made it impossible for her to perform her work duties, and she subsequently filed a slip and fall claim against the convenience store and its insurance companies. After legal proceedings, she was awarded $12.2 million to cover the cost of her damages, including lost wages and earning capacity.

The woman's attorneys presented the case in a way that was similar to a wrongful death claim, emphasizing that the woman's quality of life had been severely impacted by the accident. To those close to her, it was as though she had died as a result of the fall.

Computer Operator Suffers Ankle Fracture

A 53 year-old computer operator suffered an ankle fracture and other injuries requiring hospitalization when she slipped and fell during a lunch break while attending computer classes. The puddle was located on the patio of defendant’s premises. The plaintiff contended that the poor condition of the patio was the cause of the accident and her injuries. After trial, the parties settled the lawsuit for $125,000.

Tennessee Woman Received $525,000 in Damages

The case of Corley v. Wal-Mart Stores East, LP involved a woman who slipped and fell while in a store in Antioch, TN, resulting in serious injuries. The woman claimed that she had stepped in water and slipped. Although there was no security footage of the fall, the store's video footage showed that employees were cleaning up a large area following her injuries and an employee had walked through the area just before the fall.

The court found that Walmart was 90 percent responsible for the woman's injuries and awarded her $525,000 in damages. An appellate court later confirmed the ruling and the amount of compensation awarded to the victim.

Target Slip & Fall Results in $2.1 Million Verdict

On December 14, 2013, Horton experienced a slip and fall accident on a recently mopped floor. The floor had been cleaned due to a soda bottle spill in a primary walkway. The employee responsible for the clean-up used a "wet soapy substance" and placed warning cones near the area. However, Horton claimed that the mopping was done carelessly, resulting in much of the residual moisture being present outside the marked hazard zone.

Patron Injured in Slip and Fall at Restaurant Receives Settlement

While dining at the defendant's restaurant, the plaintiff slipped and fell on a liquid substance while walking towards her table near the service area of the bar. The plaintiff claimed that the defendants were responsible for their negligence in maintaining a hazardous condition in the bar area and failing to post warning signs or take appropriate action to rectify the situation. The plaintiff sought compensation for medical expenses and injuries. The defendants argued that the plaintiff failed to provide evidence that they were aware or should have been aware of the dangerous condition. Despite the defendants' arguments, the plaintiff was awarded damages for medical expenses, past and future suffering, and loss of enjoyment of life until the date of the verdict, totaling $160,665.

Elderly Woman Awarded $265,000

An 88-year-old client slipped and fell on water that had accumulated on the floor of a store, resulting in a fractured right hip that required surgical intervention. The accident took place on a rainy day, and evidence indicated that other customers had tracked in the water. The store was aware of the water on the floor but failed to place adequate mats to prevent slips and falls. The settlement was reached just before the trial was due to begin. It is believed that this settlement is one of the highest ever awarded in Connecticut for a slip and fall case involving an individual in their late 80s who sustained a fractured hip.

Frequently Asked Questions

What is DCOF and SCOF?2024-01-31T14:25:51+00:00

SCOF- Static: Measures the amount of force required to initiate movement or cause slipping when a person is standing still on a surface. It is important to note that standards for measuring SCOF have all been withdrawn.

DCOF- Dynamic: The dynamic (or kinetic) coefficient of friction (DCOF) is the measure of the resistance to motion between two surfaces that are already in motion relative to each other. In practical terms, it refers to the amount of force needed to keep an object sliding or moving over a surface once it has already started moving. For instance, when considering a person walking, it’s the level of resistance they feel underfoot while in motion, impacting their ability to walk without slipping.

What is a Pendulum Test Value (PTV)?2024-01-19T19:48:09+00:00

PTV stands for the Pendulum Test Value, a measurement of how slippery a surface is, measured with a tribometer called the British Pendulum, which stimulates a foot swinging across a surface.
Check out the graphic below to understand where your PTV should be at in order to be considered in the ‘Low Slip Potential’ category.

What is the cost for this service?2024-01-19T19:28:11+00:00

Any pool deck or outdoor area under 1,000sqft is a flat rate of $1,850. Areas over 1,000sqft is $2.25 per sqft. This price is on ‘never been sealed before’ surfaces. Click here for more information!

There are many paver and travertine sealing companies out there, what makes you different?2024-01-12T18:44:16+00:00

This is true. There are plenty of other companies that will seal your travertine and/or paver surfaces. Some even offer slip resistance as well. However, what they do to achieve “slip resistance” is they add a rounded plastic aggregate to the surface, like “Shark Grip”. Majority of the pool decks we are called out to, have been treated in this manner and all fail to meet the 0.55 requirement. The best way to think about it, is that we don’t sell sealing services… we are selling safety. If you want to seal your travertine or paver surface, there is only one company that can do it with a scientifically proven method for slip resistance!

So if you are going to make my travertine non-slip, does that mean that I have to give up the gloss?2024-01-12T18:44:53+00:00

No! That’s the beauty with our system! We can offer a highly-glossy finish WITH the safety of ANSI A326.3 compliant floors!

Is there a standard for travertine and paver slip resistance?2024-01-12T18:44:31+00:00

All exterior surfaces are expected to meet the DCOF threshold of 0.55 under wet conditions.

Is it cheaper to do the travertine sealing without the anti-slip?2024-01-12T18:45:20+00:00

We will not accept or do any job without the anti-slip. We are selling safety!

Do I need to seal my travertine?2024-01-12T18:45:41+00:00

It is recommended to seal your travertine to protect from mold, dirt, mildew and to give it longer life.

Why should I consider traction enhancing treatments for my floors?2024-01-12T18:40:08+00:00

It is estimated that 85% of worker’s compensation claims are attributed to employees slipping on slick floors (Industrial Safety & Occupational Health Markets 5th edition). Slip-and-fall accidents are the leading cause of visits to the ER and are the leading cause of all accidental deaths in homes each year. We can help prevent these slips and falls with our range of products for almost all surface types.

Check out our Remediation page for more information as well.

What types of surfaces can you work with?2024-01-12T18:40:37+00:00

We have a solution for every floor surface there is! To date, we have not come across a surface we have not been able to dramatically increase the Coefficient of Friction!

Is special maintenance required after application?2024-01-12T18:41:03+00:00

We do recommend that you use our ReBoost Cleaning Solution to clean your floors and we are also available to do a training session with your staff to show the proper way of cleaning and maintaining your treated floors.

How long does a treatment last?2024-01-12T18:40:23+00:00

This depends on the surface solution for your floor. Every floor is different and requires a different method of installation to achieve a safe floor. Some treatments can last up to 7 years! We recommend quarterly testing to monitor the DCOF after treatment.

Do you provide legal documentation?2024-01-12T18:37:58+00:00

Yes, our testing concludes with a legal document that is in accordance with both the ASTM F1694-14 “Standard Guide for Composing Walkway Surface Investigation, Evaluation and Incident Report Forms for Slips, Stumbles, Trips and Falls” and the ASTM F2048-00 “Standard Practice for Reporting Slip Resistance Test Results.” Our testing follows the Daubert Principle and therefore it is admissible in the court of law.

What is the difference between SCOF and DCOF?2024-01-12T18:37:15+00:00

Static friction is friction that occurs between two bodies in contact with one another while they are at rest. It’s friction which prevents an object from moving while it is still. Dynamic (or kinetic) friction is friction that opposes the movement of a body which is already in motion. It’s friction that slows or stops an object from moving.

What test method do you use?2024-01-19T19:51:40+00:00

We are able to provide testing for the following standards:

  • ANSI A326.3 (DCOF)
  • ANSI A137.1 (DCOF)
  • NFSI B101.1 (SCOF)
  • ASTM E303 (PTV)*
    • Please note that classifications under the ASTM E303 Test Method is also compatible with the following international standards:
      • CEN/TS 1615:206
      • BS 7976-2:2002+A1:2013

We test using the BOT-3000e and the British Pendulum Skid Tester. Both tribometers are calibrated and certified.

Why should I consider slip testing?2024-01-19T19:40:16+00:00

According to a study done by CNA Insurance, 50% of all floor surfaces in the United States are under the ANSI A326.3 standard of interior, wet dcof value of 0.42. We recommend you use the ANSI A326.3 standard to monitor and track your dcof levels.

If you are concerned with slip potential, we recommend you look at the ASTM E303 standard. The British Pendulum is backed by 50 years of international research and is able to provide a very accurate reading for insight into your floor’s slip potential (see graph below).
