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.

Evaluating Slip Resistance How can employers make a solid assessment of slip resistance? If the floor is likely to be lubricated with water or grease in use, it needs to be anti-slip under these expected conditions. This is recorded as the “DCOF”, or the amount of friction necessary to drag dynamic meaning “in motion” the standardized rubber across the flooring. The Variable-Angle Ramp is a German-developed method for obtaining pedestrian slip resistance values.

Retrieved from ” https: This Whole Shoe test standard is applicable to a variety of footwear materials and test surfaces, including those that are contaminated with slippery substances. Like the insole, the upper does not directly determine slip resistance, but plays a key role in fit and comfort.

Durability Slip resistance performance may change as footwear undergoes normal wear and tear. However, SCOF tests should never be used to determine if a floor is slippery when wet. Slip resistance is a challenge. The BOT is no longer being manufactured or serviced by the manufacturer. The pendulum is also the instrument used in the Sustainable Slip Resistance test method, which measures the possible impact of years of use on a potential flooring’s slip resistance.

Setting the Standard Any safety footwear provided can claim slip resistance, precisely because there is no uniform standard or rating for slip resistance.

The Tortus is now the primary instrument for assessing dry slip resistance in the latest Australian slip test standard – AS By using this site, you agree to the Terms of Use and Privacy Policy. If the shoe or boot sticks to the work surface, employees run the risk of injuries similar to those experienced by athletes who hurt their knees when their cleats stick in the turf.

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.


Tread Look for outsoles that channel oil and grease away so the outsole can reach the work surface more fully, as well as outsoles with split and solid lugs specifically designed to shed debris.

Stand Your Ground — Occupational Health & Safety

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 frictionbut 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.

Employers accustomed to requesting Mark II test data from safety footwear providers should instead ask for Whole Shoe test data according to F Monitoring changes in dry SCOF can be a useful practice.

The advantage of the Tortus, compared to the f6177, is that it can perform many slip tests wstm a short period of time, dry and wet, using both hard and soft rubbers. The TracScan is the fifth generation of robotic tribometers originally engineered and manufactured in Germany since The sample is slowly inclined until the operator slips on the surface. There are also barefoot area recommendations based on pendulum tests with a soft rubber slider TRL rubber also known as Slider The Tortus digital tribometer slip resistance test method is based on a proprietary or patented device, which makes it ineligible to become an ASTM standard.

The method is applicable to all types of footwear, outsole units, heel top-pieces top-lifts and sheet soling materials. This test method provides a measurement procedure setting forth DCOF ranges which facilitate remediation of walkway surfaces when warranted.

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.

All slip resistant f6177 should be tested to this standard to establish a common basis for comparison. The pendulum is also used in the U. Tests can be done dry and wet, and extensive research by U. Here are some general guidelines to consider when selecting the right slip resistance features:.

To assess a floor’s slip resistance, a reliable, thoroughly researched in interlaboratory studies floor friction test method must be used, and then a minimum safety criterion 0. Establishing a Reference Standard”.

In the Whole Shoe test, the footwear sole and underfoot surface are brought into contact, subjected to a specified vertical force for a short period of static contact, and then moved horizontally relative to one another at a constant speed. CTIOA has endorsed a minimum dynamic coefficient of friction for level floors of 0.


From Wikipedia, the free encyclopedia. March Learn how and when to remove this template message. For this reason, Red Wing Shoe Company recommends three simple principles for evaluating slip resistance: Follow the ASTM standard test method. When it comes to footwear, the topic of slip resistance is almost as treacherous as the slick floors, wet surfaces, and uneven terrain employees encounter every day.

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.

Outsole Soft rubber compounds offer the greatest slip resistance for environments contaminated with oil and grease. The amount of friction created by this piece of rubber as it is dragged across the flooring dry or wet is recorded and calculated by the machine as it travels a predetermined path length.

ASTM F 1677 Slip-Resistance Footwear Standards

SlipAlert is a matchbox car-like tribometer that is designed to mimic the readings of the pendulum. ASTM F provides the most complete approach to evaluating how different footwear materials interact with various work surfaces.

Softer soles and more tightly spaced treads are better suited to fluid contaminants in indoor environments. Safety features have to exist in proper balance with comfort. If the F677 stops short, then the flooring is slip resistant, but if it slides a long distance then the floor is considered slippery.

Standards Australia HB Slippery flooring produces readings close to zero, and flooring which show higher resistance to slipping give results further from zero—high numbers such as those 36 and above indicating suitable slip resistant flooring. Archived copy as title Articles with ibid from March This test method provides a measurement procedure setting forth SCOF traction ranges that facilitate remediation of walkway surfaces when warranted.

Midsole The midsole should provide ample support and f16677 is are important for the overall structural integrity of footwear. National Bureau of Standards in the s and further refined in the UK. Here are some general guidelines to consider when selecting the right slip resistance features:
