The ball is caused to rub against the disk 1mm stroke at a frequency of 50 Hz for 75 min. 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. This dkn helps evaluate fin and wear parameters of piston ring liner material in presence of engine oils.
Contact us for a live Demo or additional information. Materials are tested in pairs under nominally non-abrasive conditions.
The tests can be done in controlled environmental conditions including humidity, temperature and more. Twist Compression is designed to measure friction and adhesion in metal forming. Stribeck curve is a plot between coefficient of friction and bearing number.
Linear Oscillating The standard Test to determine extreme pressure, friction wear properties of lubricant greases, solid bonded films, gear and hydraulic fluids, lubricating oils. Fast Exchange makes all these modules easily swapable on the MFT platform.
Such a use of this standard is encouraged as a means to improve wear testing methodology. Tapping Torque, Twist Compression, Drilling Tapping torque module allows to characterize friction, wear, torque etc. The coefficient of friction may also be determined. All tests are done in oscillation mode under controlled environmental dln.
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. Temperature and recirculation addons are also available. Stribeck Curve Stribeck curve is a plot between coefficient of friction and bearing number. Thank you for your interest and filling out the form! The value of any wear test method lies in predicting the relative ranking of material combinations. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The standard Test to determine extreme pressure, friction wear properties of lubricant greases, solid bonded films, gear and hydraulic fluids, lubricating oils. Since the pin-on-disk test method does not attempt to duplicate all the conditions that may be experienced in service dij example; lubrication, load, pressure, contact geometry, removal of wear debris, and presence of corrosive environment5034 is no insurance that the test will predict the wear rate of a given material under conditions differing from those in the test.
Piston Ring Liner This test helps evaluate friction and wear parameters of piston ring liner material in presence of engine oils. Work Item s – proposed revisions of this standard. Link to Active This link will always route to the current Active version of dun standard. No other units of measurement are included in this standard.
High-load and high-temperature tribometer
The test involves rotating one ball on three stationary balls at controlled environmental conditions. Idn principal areas of experimental attention in using this type of apparatus to measure wear are described.
In this latter case, the results cannot be compared to the ILS data Table 2. Loads from mN to 10,N.
ASTM G99 – 17 Standard Test Method for Wear Testing with a Pin-on-Disk Apparatus
In all modules listed above user can change the load and velocity to automatically plot Stribeck Curves with ease. Real time down force controlpiezo sensors to measure inline friction makes this module very reliable and repeatable.
The test setup allows to mount real pieces of actual piston ring and liners. Test involves slowly rotating a ring on top of material of choice.
