Microcomputer - controlled Four - ball Friction Testing Machine

Applicable Standards：

When conducting tests, the microcomputer - controlled four - ball friction testing machine needs to comply with the following relevant national or international standards: GB/T 12583 - 98: Method for Determination of the Extreme - Pressure Properties of Lubricants (Four - ball Machine Method). GB 3142 - 82: Method for Determination of the Load - Carrying Capacity of Lubricants (Four - ball Method). SH/T 0189 - 92: Method for Determination of the Anti - wear Properties of Lubricating Oils (Four - ball Machine Method). SH/T 0202 - 92: Method for Determination of the Extreme - Pressure Properties of Greases (Four - ball Machine Method). SH/T 0204 - 92: Method for Determination of the Anti - wear Properties of Greases (Four - ball Machine Method). These standards specify the requirements for the test methods, test conditions, data processing, etc. of the four - ball friction testing machine to ensure the accuracy and comparability of test results.
