Floor slip resistance testing is the science of measuring the coefficient of friction of flooring .. The former ASTM F was the test method for the Brungraber Mark II (also known as Portable Inclinable Articulated Strut Tribometer or PIAST) . Buy ASTM F TEST METHOD FOR USING A PORTABLE INCLINEABLE ARTICULATED STRUT SLIP TESTER (PIAST) from SAI. In relation to these two tests are the ASTM F (Mark II) and ASTM F ( English) standards. Both of these standards for measurement.

Shortly after being published inASTM withdrew these standards inwith no replacement. CTIOA has endorsed a minimum dynamic coefficient of friction for level floors of 0.

Stand Your Ground — Occupational Health & Safety

It is possible for safety footwear to be too slip resistant for the job. It’s unlikely the least expensive safety footwear will meet the slip resistance requirements of the job. Tests can be done dry and wet, and extensive research by U.

Outsole Soft rubber compounds offer the greatest slip resistance for environments contaminated with oil and grease. Here are some general guidelines to consider when selecting the right slip resistance features:. The Tortus is now the primary instrument for assessing dry slip resistance in the latest Australian slip test standard – AS Flooring samples are mounted horizontally on the ramp tester and an operator clad in safety boots or bare feet performs a standardized walk up and down the sample while wearing a harness to stop the operator from being injured.

Slip resistance testing or floor friction testing is usually desired by the building’s owner or manager when there has been a report of a slip and fall accident, when there has been a report of a near accident, or preferably before the flooring is installed on the property. This makes it a credible forensic science device.

For many years, this test was an accepted standard for measuring slip resistance of walkway surfaces and evolved into testing footwear.

This is recorded as the “DCOF”, or the amount of friction necessary to drag dynamic meaning “in motion” the standardized rubber across the flooring. It is vital to avoid clogging the tread. Safety features have to exist in proper balance with comfort. Insoles Insoles do not play a direct role in slip resistance, but they should offer additional cushioning and impact padding for employees who are on their feet for extended periods or work on hard surfaces.


This puts employers in a difficult position because slips, trips, and falls are among the most reported—and most costly—injuries in many industries. Look for a provider with experience developing purpose-built safety footwear worn in a variety of industries.

Dry slip f167 is not an indicator of wet slip resistance — in fact the two often vary inversely — so reliable wet slip resistance testing is often needed as well as reliable dry testing. There have been numerous floor slip resistance testing tribometers and lab devices produced around the world to measure both the static stationary and dynamic in motion coefficient of friction aztm, but presently there are only a few that have been proven to be reliable for obtaining useful safety results and that have current official test methods.

They are still available for purchase from ASTM as a withdrawn or “historical” standard. See “external links” at the bottom of this page for more information on the inadequacies of ff1677 C test.

Exploring a Slippery Issue Measuring slip resistance for qstm footwear can be challenging. Webarchive template wayback links CS1 maint: As such, it offers a comprehensive picture of the slip resistance of footwear. The TracScan will analyze the walkway’s slip-resistance level and provides the quantitative values which are extremely valuable and are effectively used in slip-and-fall related lawsuits and floor safety monitoring programs.

Excerpts from the Whole Shoe test documentation illustrate three reasons why:. It is ideal to work with a safety footwear provider who understands these tradeoffs and can help advise your organization on the right product for the work environment.

ASTM F Slip-Resistance Footwear Standards |

Users of these instruments and also the Brungraber Mark IIIB have, in recent years, begun citing that their instruments are now able to pass ASTM F, claiming this makes their instrument “valid” for investigating slips and falls. Employers should prioritize durable footwear that provides the most slip resistance for the longest period of time. Zstm from the Whole Shoe test documentation illustrate three reasons why: IndustrySafe is here to help. The Tortus digital tribometer slip resistance test method is based on a proprietary or patented device, which makes it ineligible to become an ASTM f1767.


Midsole The midsole should provide ample support and stability is are important for the overall structural integrity of footwear. Archived from the original on Archived copy as title Articles with ibid from March The following text summarizes the standard: The pendulum is also used in the U. Treads should allow a maximum amount of material to grip the floor. Retrieved from ” https: This test method determines the dynamic coefficient of friction between footwear and floorings under reproducible laboratory conditions for evaluating relative slip performance.

When the arm of the pendulum is set up to miss the flooring completely, the arm swings up to parallel from where it started, and the pointer brought along by the arm holding the rubber slider reads zero. The BOT is no longer being manufactured or serviced by the manufacturer.

The method is applicable to all types of footwear, outsole units, heel top-pieces top-lifts and sheet soling materials.

However, since it is measuring real human ambulation, it is considered by many to be the most realistic test method in existence, and the results of pendulum and drag-sled meter tests are sometimes compared ashm results from variable-angle ramp tests to see if the results have a strong correlation. There is a digital readout on the device that records the maximum distance the SlipAlert has traveled across the flooring, and a safety criterion graph which interprets the results. If safety footwear does not fit properly or is uncomfortable, employees may not wear them consistently or find excuses to avoid wearing them.

ASTM F1677 Non-Slip Test Instrument

There are also barefoot area recommendations based on pendulum tests with asttm soft rubber slider TRL rubber also known as Slider Views Read Edit View history. The following text summarizes the standard:. This page was last edited on 18 Novemberat But as noted earlier, an instrument must be able to pass ASTM F, but must also be able to provide a “reasonable precision statement” required from all standards publishing agencies. Setting the Standard Any safety footwear provided can claim slip resistance, precisely because there is no uniform d1677 or rating for slip resistance.
