HPR

The HPR is a next-generation friction and wear test system with a fully sealed pressure chamber, which is able to run under high-pressure or vacuum.
A unique removable chamber design maintains pressure or vacuum even when off the system, which allows test blends to be made in-situ. Combined with low cost standard specimens and small test sample volumes, the HPR represents a fast, reliable and cheap way to test fuels and lubricants.

Applications for the HPR include:

• Volatile fuels and blend studies.
• Inert gas studies, the small volume of the chamber allows test fluids to be changed in situ and – if necessary – during a test.
• The behaviour of low volatility lubricants under very low pressures, giving direct friction and wear measurements under precise test conditions.
• Lubricity studies under controlled atmosphere, for example hydrogen.
• Lubricity of volatile fuels.
• The behaviour of refrigerants under high pressure.
• The study of surface morphology and microstructure of coatings under controlled environments.
