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).

ASTM E is used for road and paving standards. Static Coefficient Friction is between non-moving surfaces; it can prevent an object or person from sliding down a gradient surface. It relies on a carbon dioxide cartridge, not gravity, therefore providing more accurate results and also allowing for inclined surfaces to be tested.

R2047 involves the James Machine with a leather friction pad measuring static friction, and specifies that all testing must be performed dry. Dry surfaces are mostly tested by this method, wet measurements are possible but erratic. 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.

Dry slip testing can also be useful with or without wet testing. Its findings were published in Further, this test method also establishes a compliance criterion to meet the requirement for a nonhazardous polished walkway surface.

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. Link to Active This link will always route to the current Active version of the standard. The Neolite is called the sensor. Safety on flooring and ramps is one of the most common reasons for concern about the static coefficient of friction.

The BOTE performs a test without human input except for setup and the pressing of an electronic button.

There are manufacturing process reasons as well, such as stamping. The values given in parentheses are mathematical conversions to SI units that are provided for information only and sstm not considered standard. There are also barefoot area recommendations based on pendulum tests with a soft rubber slider. Each has its own appropriate safety standard se. A high traction rough surface with large scale roughness due to large sand particles is shown in a macro photograph.

c2047 We do not perform this measurement. The James Machine needs continuous maintenance and adjustment in order to measure correctly due to the fact that an 80 pound weight is asfm of asm test. The meter itself provides the applied weight on a horizontal surface of the material adtm be tested.

SlipAlert left is a roller-coaster type tribometer that is designed to mimic the readings of the modern pendulum. 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 above standards require measurements of the SCOF in each of four orthogonal directions. 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 roots of D can be traced to the late s and Sidney James of Underwriters Laboratories, the inventor of ast, machine used in this standard. 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. CTIOA has endorsed a minimum dynamic coefficient of friction for level floors of 0.

Here you can find a Tortus video demonstration. Historical Version s – view previous versions of standard. It now has an official British standard for its use in the field — BS Anderson Materials Evaluation, Inc. The average value is then used to determine if the SCOF is adequately high for a safe walking surface.

Walkway materials which are occasionally wet or normally wet are to have a wet surface SCOF greater than or equal to 0. Feel free to contact us with any questions.
