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).

Direct questions and comments to contactus andersonmaterials. They have also been used by cruise ship companies and others outside of Australia.

The advantage zstm the Tortus, compared to the pendulum, is that it can perform many ashm tests in a short period of time, dry and wet, using both hard and soft rubbers. This test is often conducted and interpreted by people who have a vested interest in their tribometer having passed the test, and it should not be solely relied upon in deciding whether a slip tester is trustworthy in predicting human traction.

Safety on flooring and ramps is one of the most common reasons for concern about the static coefficient of friction. The Sigler is no longer commercially available, but c2047 few survive.

Both hard and soft rubbers are specified for the pendulum, with soft rubber being dd2047 primarily to barefoot situations such as showers, bathroom floors, and swimming pool decks.

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.

Static Coefficient of Friction Measurements

Historical Version s – view previous versions of standard. Many government regulations are based upon ASTM standards. This method is not capable of valid pedestrian safety testing under wet conditions. Inthe Tortus III became an official part of the Australian floor slip test standard AS where it is used as the primary instrument for making dry floor slip resistance readings. There are manufacturing process reasons as well, such as stamping.


The colored UV coating is filled with complex silicates, calcium sulfate, and carbonate fine particles which provide a shorter-range roughness for this walking surface. ASTM C for the Horizontal Pull Dynamometer has now officially been withdrawn as a test method in and was intended for quality assurance testing of ceramic tile in and out of the factory.

The pendulum is the basis of the Sustainable Slip Resistance standard that has been specified by McDonalds Restaurants since The James Machine needs continuous maintenance and adjustment in order to measure correctly due to the fact that an 80 pound weight is part of the test.

Slip testers such as these can, however, be somewhat useful in determining whether floor maintenance practices are affecting slip resistance over time by using it as a regular monitoring device on dry floors. ASTM withdrew this standard inwith no replacement. The compliance criterion is based on extensive experiential data from residential, commercial, industrial and institutional walkway surfaces since We can also examine surfaces with FTIR spectroscopy to characterize polymeric material surfaces.

The static coefficient of friction depends both upon the chemistry of the surfaces and the morphology of the surfaces. Click here to see a SlipAlert Video Demonstration. Federal Trade Commission congressionally mandated to resolve conflicting advertising claims for “slip resistant” polishes ruled that only polishes that passed the compliance criterion of D could be termed as slip resistant.

It measures the energy loss when a rubber slider is moved over the square foot testing surface.

See a video demonstration of the BOTE. Kinetic friction is between moving surfaces; it measures the friction between two surfaces moving against each other such as a book being pushed across a table or a sled being dragged across the ground. Anderson Materials Evaluation, Inc. 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.

CTIOA has endorsed a minimum dynamic coefficient of friction for level floors of 0. Leather and other test foot materials are also available for this instrument.

This test method, like the former ASTM Cis not based on actual slip and fall research, however. ASTM is a type of test that is approved for both wet and dry testing. This surface then has roughness on three scales and has the unusual property of having satm even higher SCOF when wet than when dry.

s2047 SlipAlert left is a roller-coaster type astj that is designed to mimic the readings of the modern pendulum. The method applies only to the HPS and not to any other device. Many machines have been created to measure coefficient of friction. Many other parties benefit financially from these accidents or sale of the slippery flooring that often causes them: The English XL Tribometer mimics the human stepping motion and allows for synchronized application of vertical and horizontal forces.

Some slip measurement advocates are wrongly claiming that the dynamic coefficient of friction is a more important value than the static coefficient of friction.

Slip Resistance Testing Standards in 2018

Our knowledge and experience in the field of floor slip resistance testing is unmatched in the Americas. We do not perform this measurement. A surface with an adequate average may actually have an unsafe SCOF in asttm particular direction. The Technical Products Model 80 is a static slip tester as well and therefore is not suitable for wet testing to assess anti-slip pedestrian safety.
