1. High Speed Ring-Block Wear Testing Machine Application
MRH-5 is mainly applied for simulating evaluation for kinds of lubricant, grease's extreme compression capacity and anti-confusion capacity. It can also be used for performance study of anti-friction capacity of aviation kerosene and capacities of all sorts of paint coating, metal and non-metal materials.
2. High Speed Ring-Block Wear Testing Machine Standards
This machine conforms to ASTM D 2782 Standard Test Method for Measurement of Extreme-Pressure Properties of Lubricating Fluids (Timken Method) and ASTM G77 Standard Test Method for Ranking Resistance of Materials to Sliding Wear Using Block-on Ring Wear Test
