In this video, friction force between a steel ball and the plate applied lubricant to is measured (ball-on-plate test) by VWF-10N with Φ6 ball holder VWF-BAH6 (sold separatly). The included software allows you to not only graph the relationship between force and time, but also easily calculate the average kinetic/static coefficient of friction and overlay the data so that you can see the difference of kinetic coefficient of friction between the ball and plates with/without lubricant.

This is a friction test of film complying the corresponding part of ASTM D1894 (2014) using a customized coefficients of friction attachment for large sample. The included software enables you to graph the relationship between force and time and automatically calculates the static and kinetic coefficients of friction once the weight mass is input.

This video is about measurement friction force of a pen, one factor of writing comfort, by using our variable weight reciprocating friction test jig. You can also generate vertical force like writing pressure by placing weight you prepared on the plate. The test result is easily graphed or calculated into coefficient of dynamic friction by supplied software. You can also overlay the graphs and compare test results of different types of pens.

This coefficient of friction (COF) test is performed to measure sliding friction of packaging film for quality control and R&D. It enables testing according to the corresponding part of JIS standard.

To determine coefficient of friction (COF) of paper, pull the weight with sample to slide it against the sample on the table, then calculate the COF by the supplied software. It complies with the corresponding part of JIS P8147: 2010. IMADA offers the dedicated testing system such as the following configuration, which is widely used in quality control and R&D.
