The ball is caused to rub against the disk 1mm stroke at a frequency of 50 Hz for 75 min. The value of any wear test method lies in predicting the relative ranking of material combinations. Materials are tested in pairs under nominally non-abrasive conditions.
Fast Exchange makes all these modules easily swapable on the MFT platform. 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. This test helps evaluate friction and wear parameters of piston ring liner material in presence of 53024 oils.
Loads from mN to 10,N. The tests can be done in controlled environmental conditions including 05324, temperature and more. Stribeck curve is a plot between coefficient of friction and bearing number.
High-load and high-temperature tribometer
Historical Version s – view previous versions of standard. In this latter case, the results cannot be compared to the ILS data Table 2. Stribeck Curve Stribeck curve is a plot between coefficient of friction and bearing number. Idn, 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 5324 Test Method G99 results.
All tests are done in oscillation mode under controlled 5024 conditions. Linear Oscillating The standard Test to determine extreme pressure, friction wear properties of lubricant greases, solid bonded films, gear and hydraulic fluids, lubricating oils.
ASTM G99 – 17 Standard Test Method for Wear Testing with a Pin-on-Disk Apparatus
Thank you for your interest and filling out the form! Temperature and recirculation addons are also available. Piston Ring Liner This test helps evaluate friction and wear parameters of piston ring liner material in presence of engine oils. Test involves slowly rotating a ring on top of material of choice.
Such a use of this standard is diin as a means to improve wear testing methodology.
Link to Active This link will always route to the current Active version of the standard. The coefficient of friction may also be determined.
No other units of measurement are dim in this standard. The principal areas of experimental attention in using this type of apparatus to measure wear are described.
The test setup allows to mount real pieces of actual piston ring and liners.
Since the pin-on-disk test method 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. Real time down force controlpiezo sensors to measure inline friction makes this module very reliable and repeatable.
High-load and high-temperature tribometer – Fraunhofer IST
In all modules listed above user can change the load and velocity to automatically plot Stribeck Curves with ease. Tapping Torque, Twist Compression, Drilling Tapping torque module allows to characterize friction, wear, torque etc. Work Item s – proposed revisions of this standard.

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.
