Summary of test method

The principle of using the ball-on-plate friction design is that the ball from the kit will be fixed in a holder located in a vertical position, and then pressed against a metal plate, which is pre-positioned horizontally. The ball makes reciprocating movements with adjustable length and stroke frequency. It is important for the ball to be completely immersed into fuel with a certain temperature. Any specifications either the temperature of the fuel or the properties of the ball and plate, are precisely set.


Our products are fully compliant with GOST R ISO 12156-1. Each set has 100 balls and plates.
