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).

Axtm C for the Horizontal Pull Dynamometer has now officially been withdrawn as a test method in and was intended for quality assurance testing of ceramic tile in and out of the factory.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 experiential data was collected by an independent accounting firm for the Chemical Specialties Manufacturers Association. This is now part of the International Building Code.
Different slip resistance test methods give different results, particularly under wet conditions. They have also been used by cruise ship companies and others outside of Australia.
Static Coefficient of Friction Measurements
It has been used for field testing, but is of limited utility in laboratory testing because it requires d20047 long path length of flooring. Measurements can be made in accordance with the following standards, except that the contact area and the applied weight may differ: Each has its own appropriate safety standard se. Skip to main content.
Static coefficient of friction slip testing is therefore irrelevant.
The BOTE performs a test without human input except for setup and the pressing of an electronic button. By examining each standard and the test that is performed for each, you can choose which non-skid flooring option best suits your applications needs. Although it is necessary for a tribometer d22047 pass this test, it is not sufficient in validating a scientific slip test instrument.
ASTM E is used for road and paving standards. ASTM withdrew this standard inwith no replacement. Once slippage has begun, a higher dynamic coefficient of friction may help one to recover from a slip, but it x2047 better to prevent the slippage in the first place. Many government regulations are based upon ASTM standards. View interactively in English Spanish Chinese. We do not recommend its use.
Testing the Safety of Polished Floors | ASTM Standardization News
It is a laboratory machine that tests flooring samples and due to aastm design is not usable on an actual floor. Despite the fact that the ADA never truly endorsed this test method, a great deal of confusion has resulted and misinformation abounds amongst flooring and construction professionals about this poor test method.
Currently, there is only one computerized version in production and four versions of the machine have been created since The compliance criterion is based on extensive experiential data from residential, commercial, industrial and institutional walkway surfaces since It measures the energy loss when a rubber slider is moved over satm square foot testing surface.
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. It is still available from ASTM as a withdrawn or historical standard. Static friction and Dynamic or Kinetic friction are the two types of coefficient of friction that are used to determine how safe a floor can be.
Test results are usually quoted as Pendulum Test Values ast, avoid the confusion that v2047 when different devices are used to give different values of coefficient of friction. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.
Slip Resistance Testing Standards in 2018
They found that if a polish produced a value of 0. A high traction rough surface with large scale roughness due to large sand particles is shown in a astn photograph.
Both hard and soft rubbers are specified for the pendulum, with soft rubber being applied primarily to barefoot situations such as showers, bathroom floors, and swimming pool decks. The meter has three feet which are Neolite for standard slippage testing purposes. This device is not patented. Its findings were published in It was once cited by the U. It involves the James Machine with a leather friction pad measuring static friction, and specifies that all testing must be performed dry.
Of course, for other applications there are cases in which one desires a more slippery surface and these additional surface characterizations are useful then as well.
