ASTM D5707<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1<\/span> This test method covers a procedure for determining a lubricating grease’s coefficient of friction and its ability to protect against wear when subjected to high-frequency, linear-oscillation motion using an SRV test machine at a test load of 200\u2009N, frequency of 50\u2009Hz, stroke amplitude of 1.00\u2009mm, duration of 2\u2009h, and temperature within the range of the test machine, specifically, ambient to 280\u2009\u00b0C. Other test loads (10\u2009N to 1200\u2009N for SRVI-model, 10\u2009N to 1400\u2009N for SRVII-model, and 10\u2009N to 2000\u2009N for SRVIII-model), frequencies (5\u2009Hz to 500\u2009Hz) and stroke amplitudes (0.1\u2009mm up to 4.0\u2009mm) can be used, if specified. The precision of this test method is based on the stated parameters and test temperatures of 50\u2009\u00b0C and 80\u2009\u00b0C. Average wear scar dimensions on ball and coefficient of friction are determined and reported.<\/p>\n

Note 1:<\/span> Optimol Instruments supplies an upgrade kit to allow SRVI\/II-machines to operate with 1600\u2009N, if needed.<\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n

1.2<\/span> This test method can also be used for determining a fluid lubricant’s ability to protect against wear and its coefficient of friction under similar test conditions.<\/p>\n<\/p><\/div>\n

\n

1.3<\/span> The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n<\/p><\/div>\n

\n

1.4<\/span> This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.<\/i><\/p>\n<\/p><\/div>\n

\n

1.5<\/span> This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.<\/i><\/p>\n<\/p><\/div>\n
