The analysis method of friction and wear test includes comparison test method, use range test method, performance test method, and the analysis according to actual use test. The contrast test method is the highest frequency and the most convenient operation analysis method in practice. Let's introduce it.

Under the same conditions, several samples or the tested samples are compared with the known standard samples to compare the friction and wear properties, so as to select or determine the materials and structures with better friction and wear properties.

Standard Test Method

The friction and wear properties of various materials are measured and studied by a unified standardized test method, so as to compare and select the friction and wear properties of various materials under different working conditions.

If you want to know more about it, please call the hotline 0531-85860713 and 85860723. The technical engineer of Ji'nan Heng Xu test machine will serve you wholeheartedly.
