No other units of measurement are included in this standard. Such a use of this standard is encouraged as a means to improve wear testing methodology. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Thank you for your interest and filling out dln form! Temperature and recirculation addons are also available. Loads from mN to 10,N. Fast Exchange makes all these modules easily swapable on the MFT platform. The standard Test to determine extreme pressure, friction wear properties of lubricant greases, solid bonded films, gear and hydraulic fluids, lubricating oils.
Historical Version s – view previous versions of standard. All tests are done in oscillation mode under controlled environmental conditions. This test helps evaluate friction and wear parameters of piston ring liner material in presence of engine oils.
Since the pin-on-disk test diin does not attempt to duplicate all the conditions that may be experienced in service for example; lubrication, load, pressure, contact geometry, removal of wear debris, and presence of corrosive environmentthere is no insurance that the test will predict the wear rate of a given material under conditions differing from those in the test.
Work Item s – proposed revisions of this standard. However, it must be clearly stated in any report that, while the directions and protocol in Test Method G99 were followed if truethe choices of test parameters were different from Test Method G99 values, and the test results were therefore also different from the Test Method G99 results. The value of any wear test method lies in predicting the relative ranking of material combinations.
High-load and high-temperature tribometer – Fraunhofer IST
Tapping Torque, Twist Compression, Drilling Tapping torque module allows to characterize friction, wear, torque etc. In this latter case, the results cannot be compared to the ILS data Table 2.
The test involves rotating one ball on three stationary balls at controlled environmental conditions.
Twist Compression is designed to measure friction and adhesion in metal forming. The test setup allows to mount real pieces of actual piston ring and liners. Materials are tested in pairs under nominally non-abrasive conditions. Piston Ring Liner This test helps evaluate friction and wear parameters of piston ring xin material in presence of engine oils.
The coefficient of friction may also be determined. The ball is caused to rub against the disk 1mm stroke at a frequency of 50 Hz for 75 min. Stribeck Curve Stribeck curve is a plot between coefficient of friction and bearing number. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

High-load and high-temperature tribometer
The tests can be done in controlled environmental conditions including humidity, temperature and more. Link to Active This link will always route to the current Active version of the standard.
Linear Oscillating The standard Test to determine extreme pressure, friction wear properties of lubricant greases, solid bonded films, gear and hydraulic fluids, lubricating oils. In all modules listed above user can change the load and ein to automatically plot Stribeck Curves with ease.
Stribeck curve is a plot between coefficient of friction and bearing number. Test involves slowly rotating a ring on top of material of choice. Real time down force controlpiezo sensors to measure inline friction makes this module very reliable and repeatable.
