In all modules listed above user can change the load and velocity to automatically plot Stribeck Curves with ease.
The principal areas of experimental attention in using this type of apparatus to measure wear are described. Work Item s – proposed revisions of this standard. 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 fin are also available.
Such a use of this standard is encouraged as a means to improve wear testing methodology. Piston Ring Liner This test helps evaluate friction and wear parameters of piston ring liner material in presence of engine oils. All tests are done in oscillation mode under controlled environmental conditions.
In this latter 503244, the results cannot be compared to the ILS data Table 2. Tapping Torque, Twist Compression, Drilling Tapping torque module allows to characterize friction, wear, torque etc.
Contact us for a live Demo or additional information. Fast Exchange makes all these modules easily swapable on the MFT platform.
Thank you for your interest and filling out the form! The test setup allows to mount real pieces of actual piston ring and liners.
ASTM G99 – 17 Standard Test Method for Wear Testing with a Pin-on-Disk Apparatus
Historical Version s – view previous versions of standard. The tests can be done in controlled environmental conditions including humidity, temperature and more. The coefficient of friction may also be dim. Twist Compression is designed to measure friction and adhesion in metal forming.
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. 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 500324 from Test Method G99 values, and the test results were therefore also different from the Test Method G99 results.
High-load and high-temperature tribometer
No other units of measurement are included in this standard. Stribeck curve is a plot between coefficient of friction and bearing number. This test helps evaluate friction and wear parameters of piston ring liner material in presence of engine oils. Real time down force 5034piezo sensors to measure inline friction makes this module very reliable and repeatable. Link to Active This link will always route to the current Active version of the standard.
The standard Test to determine extreme pressure, friction wear properties of lubricant 550324, solid bonded films, gear and hydraulic fluids, lubricating oils. Since the pin-on-disk dun 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject fin but are not provided as part of the standard. Loads from mN to 10,N.
High-load and high-temperature tribometer – Fraunhofer IST
Stribeck Curve Stribeck curve is a plot between coefficient of friction and bearing number. The test involves rotating one ball on three stationary balls at controlled environmental conditions.
Materials are tested in pairs under nominally non-abrasive 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.
Test involves slowly rotating a ring on top of material of choice.
