ASTM D Standard Test Method for Static Coefficient of Friction of Polish- Coated Flooring Surfaces as Measured by the James Machine. Jan 5, The ASTM E slip resistance test standard defines the British pendulum . ASTM D is the basis of the testing of floor “waxes” (floor. Oct 31, ABIC Testing Laboratories, Inc. was authorized to test the following samples of metal floor panels for static coefficient of friction (SCOF).

We provide XPS analysis of surfaces f2047 that the elemental and chemical composition of the surface in immediate contact with the sensor or opposing material is well-characterized.

The HPS is compromised of a large pad and 50 pounds of weight d207 is hand pulled across tiles to measure slip resistance. Our knowledge and experience in the field of floor slip resistance testing is unmatched in the Americas. Which one is the right test for your application? Federal Trade Commission congressionally mandated to resolve conflicting advertising claims for “slip resistant” polishes ruled that only polishes that passed d0247 compliance criterion of D could be termed d22047 slip resistant.

Walkway materials which are occasionally wet or normally wet are to have a wet surface SCOF greater than or equal to 0. Again, the James Machine is measuring static COF, which is the measure of how slippery a floor is when someone is standing still on it.

The ASTM E slip resistance test standard defines the British pendulum tester astmm is now a national standard for pedestrian floor slip resistance in 49 nations asmt five continents and has been endorsed by Ceramic Tile Institute of America since Request a quote Share to email Send to printer. Currently, there is only one computerized version in production and four versions of the machine have been created since ASTM is an international standards organization that develops and publishes technical standards for a various range of items.


The experiential data was collected by an independent accounting firm for the Chemical Specialties Manufacturers Association. Here you can find a Tortus video demonstration. Some slip measurement advocates are wrongly claiming that the dynamic coefficient of friction is a more important value than the static coefficient of friction. Link 2d047 Active This link will always route to the current Active aztm of the standard.

There are manufacturing process reasons as well, such as stamping. The above standards require measurements of the SCOF in each of four orthogonal directions.

The HPS measures both static and kinetic coefficient of friction. The Access Board later withdrew this citation, and now provides no suggested test method or safety standard. It should be noted that some surfaces have a strong directional dependence on the SCOF. Static coefficient of friction slip testing is therefore irrelevant.

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.

Slip Resistance Testing Standards in 2018

With more than a half-century of consistently predictable and accurate testing results behind it, the ASTM D standard continues to be the go-to standard for the floor polish industry, including their manufacturers, material suppliers and all users of floor polish.

Because the test method uses a dry leather pad, it gives lower COF aztm than if a Neolite or rubber pad were used. We can also examine surfaces with FTIR spectroscopy to characterize polymeric material surfaces.

The instrument includes many features that help in validating a test as to time, date of last calibration by the manufacturer, date and time of last verification by the user, date and time and astj number of test run as well as test foot slider used, age of axtm number of runs on that test foot, etc.

The advantage of the Tortus, compared to the pendulum, is that it can perform many slip tests in a short period of time, dry and wet, using both hard and soft rubbers.

These features help establish courtroom credibility. Although it is necessary for a tribometer to pass this test, it is not sufficient in validating a scientific slip test instrument.

Since friction is not a property of a surface but of an interface, holding one surface of the interface the specification leather constant will provide a measure of the friction contribution of various polish surfaces to the interface. Skip to main content.

Testing the Safety of Polished Floors | ASTM Standardization News

An anti-slip floor or slip resistant floor will be anti-slip for someone who is in motion moving adtm the floor. This test can be used on both wet and dry walking surfaces. We here at Safety Direct America can slip test your flooring in our lab or on site, or sell you your own slip resistance tester.

The roots of D can be traced to the late s and Sidney James of Underwriters Laboratories, the inventor of the machine used in this standard. It is only used for testing xstm surfaces, it is not appropriate for wet surfaces because the sensor pads that are attached tend to hydroplane, which will lead to skewed results.

Whether in an office building or on a basketball court, the safety of a polished floor is crucial to those walking, running or playing on it. Dry slip testing can also be useful with or without wet testing. We do not perform this measurement. Static Coefficient Friction is between non-moving surfaces; it can prevent an object or person from sliding down a gradient surface.
