The term pendulum test value (PTV) is synonymous with BPN in the pedestrian surface industry. The greater the friction between the slider and the test surface, the more the swing is retarded, and the larger the BPN reading. Five swings of the pendulum are made for each .
Floor slip resistance testing is the science of measuring the coefficient of friction (or resistance to slip accidents) of flooring surfaces, either in a laboratory (before or after installation) or on floors in situ. Slip resistance testing (or floor friction testing) is usually desired by the building's owner or manager when there has been a report of a slip and fall accident, when there has .Pendulum Slip Testing is a test that uses and instrument known as a pendulum skid resistance tester to measure the dynamic co-efficient of friction, this is the friction available between two objects when at least one of them is moving. This is used to .
A major source of measurement uncertainty for the pendulum friction tester is attributed to calibration. Two methods of calibrating a pendulum are presented in this paper, the first being a direct .
The distance travelled by the pendulum after striking the surface is determined by the friction resistance of the sample surface. The Pendulum Test Value (PTV), which corresponds to the co-efficient of friction times 100, can be read directly from the clearly engraved scale. Warranty. This product comes with a 3-year warranty. Intelligent PendulumAlso known as the British Pendulum Tester, Skid Resistance Tester, Portable Skid Resistance Tester, the instrument which is portable, is designed and constructed to the requirements of BS EN 1097-8:2000, and can be used to give a direct reading measurement of the following options: Road surface testingPendulum Slip Testing is a test that uses and instrument known as a pendulum skid resistance tester to measure the dynamic co-efficient of friction, this is the friction available between two objects when at least one of them is moving. This is used to .
The pendulum slip resistance test is well-researched and long backed by the ASTM (American Society for Testing and Materials) standard ASTM E303-93 that was validated and has been in use since 1993, which is about thirty years ago now. 3500 test results on walking surfaces were obtained over more than 25 years to validate this test method back in the 1970s in the United .The pendulum test is easily the world’s most reliable floor friction test for assessing the real-world slip resistance of flooring, as it can test for the dynamic coefficient of friction (DCOF) both in the lab and after the flooring has been installed and maintained, which is often crucial to avoiding slips on your property. It’s based on .

The Pendulum Skid Resistance Tester was originally designed in the 1940s in the USA and further developed in the 1960s at the TRL (Transport Research Laboratory) for the testing of road surfaces. The device measures the frictional resistance between a rubber slider mounted on the end of a pendulum arm and the surface to be tested.
ASTM E303 Test Results. The ASTM E303 standard uses the British Pendulum Tester to evaluate surface frictional properties, resulting in the Pendulum Test Value (PTV). This value indicates a surface’s dynamic coefficient of friction, with higher values indicating greater slip resistance and lower values indicating greater slipperiness.The pendulum test measures the loss of energy due to friction as the standard rubber-coated slider assembly slides across the test surface [9]. Pendulum friction tester is presented in Fig. 4. 1.4.2.2 British Pendulum Tester versus Dynamic Friction Tester. The DF Tester measures the friction between three rubber sliders and a wet pavement surface. When the rotating .
Assessing Pendulum Slip Test Ratings. To this day, there is still great debate in Australia as to assessing the risk of slipping when comparing the measurements obtained from the pendulum friction tester. Originally AS 3661.1 required that a wet surface obtain a Coefficient of Friction (CoF) of at least 0.40 (BPN of 39) for a level walking surface.
