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 so that the elemental and chemical composition of the surface in immediate contact with the sensor or opposing material is well-characterized.
The Access Board later withdrew this citation, and now provides no suggested test method or safety standard. It is a static slip tester essentially a portable version of the James Machine — see below and because it suffers from a stiction problem it is not useful for wet testing.
It measures the energy loss when a rubber slider is moved over the square foot testing surface. This physical parameter for electrical connection materials and some mechanical connections is also important. ASTM withdrew the standard in See a video demonstration of the BOTE. Because the test method uses a dry leather pad, it gives lower COF results than if a Neolite or rubber pad were used.
AME is able to investigate these surface properties in detail so that insight is gained into the reasons that given surface combinations have the friction properties they have and so that improvements in those properties may be achieved. D2407, this test method also establishes a compliance criterion to meet the requirement for a nonhazardous polished walkway surface.

They found that if a polish produced a value of 0. ASTM also withdrew this standard in with no replacement. The pendulum is the basis of the Sustainable Slip Resistance standard that has been specified by McDonalds Restaurants since Other sensor materials may be substituted for the Neolite for specialized testing.
The meter has three feet which are Neolite for standard slippage testing purposes.
This method is not capable of valid pedestrian safety testing under wet conditions. ASTM Standards and Tests for Coefficient of Friction Designed for applications where safety, durability, and longevity are vital for industrial and commercial environments. The meter itself provides r2047 applied weight on a horizontal surface of the material to be tested.
The ASTM E slip resistance test standard defines the British pendulum tester that is now a national standard for pedestrian floor slip resistance in 49 nations on five continents and has been endorsed by Ceramic Tile Institute of America since The Sigler Pendulum Tester is an older version of the pendulum tester. 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.
View interactively in English Spanish Chinese. In many cases, material surfaces have different local compositions than do the interior of the materials and it is the surface composition, along with the surface topography, which plays the critical role in determining the SCOF.

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. We can also examine surfaces with FTIR spectroscopy to characterize polymeric material surfaces. It is a pound drag sled that is pulled by a hand-held force meter dynamometerand the coefficient of friction COF is calculated from the horizontal and vertical forces. 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.
The average value is then used to determine if the SCOF is adequately high for a safe walking surface. It involves the James Machine with a leather friction pad measuring static friction, and specifies that all testing must be performed dry.
It is the responsibility of the user of this ashm to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

It is only used for testing dry surfaces, it is not appropriate for wet surfaces because the sensor pads that are attached tend to hydroplane, which will lead to skewed results.
Safety on flooring and ramps is one of the most common reasons for concern about the static coefficient of friction. Here you can find a Tortus video demonstration. However, when a surface is very rough, the decrease in traction may xstm very little when wet adtm for some very carefully engineered surfaces it may even be higher.
The tribometer has no motors, springs or anything else that may fail when testing occurs, making it the preferred testing method for ASTM Each has its own appropriate safety standard se. The HPS measures both static and kinetic coefficient of friction. It has been used for field testing, but is of limited utility in laboratory testing because it requires a long path length of flooring.
The roots of D can be traced to the late s and Sidney James of Underwriters Laboratories, r2047 inventor of the machine used in this standard. Dry slip testing can also be useful with or without wet testing. 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.
Static Coefficient of Friction Measurements
If the floor is likely to be lubricated with water, grease, etc. The James Machine needs continuous maintenance and adjustment in order to measure correctly due to the fact that an 80 pound weight satm part of the test. We have made a number of custom SCOF measurements for such applications. A surface with an adequate average may actually have an unsafe SCOF in a particular direction.
