Nippo Sangyo- D. F. Tester (Dynamic Friction tester)
ASTM : E-1911-98
The D.F. Tester is a portable instrument to measure the frictional characteristics of paved surfaces in laboratories and on field at roads, highways, airport taxi-ways, runways and other areas.Among many such instruments introduced to the market today,the D.F. Tester is being used widely not only in Japan but also in the EU, the United States and many other countries at government agencies, construction companies, independent consulting companies,automotive manufacturers, tire manufacturers, research institutions and universities among many other organizations.
The equipment has many exceptional features and characteristics that clearly gives unique advantages to the device. The easy handling and portability of the device make it ideal in using both on field and in the laboratory. Measures the friction from high speeds to static friction and depicts the friction ? speed relationship in one single measurement.The unit is easy to use and removes measurement dependency on operators and from the results, it also can be used in small restricted areas where other measurements are not possible.
