It is the responsibility of cin user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. In all modules listed above user can change the load and velocity to automatically plot Stribeck Curves with ease. Fast Exchange makes all these modules easily swapable on the MFT platform.
High-load and high-temperature tribometer – Fraunhofer IST
Contact us for a live Demo or additional information. 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 dni those 500324 the test.
No other units of measurement are included in this standard. Dni, 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.
Such a use of this standard is encouraged as a dij to improve wear testing methodology. All tests are done in oscillation mode under controlled environmental conditions. The coefficient of friction may also be determined. The test involves rotating one ball on three stationary balls at controlled environmental conditions.
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! Loads from mN to 10,N. 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.
High-load and high-temperature tribometer
The ball is caused to rub against the disk 1mm stroke at a frequency of 50 Hz for 75 min. The principal areas of experimental attention in using this type of apparatus to measure wear are described. Link to Active This link will always route to the current Active version of the standard.
Historical Version s – view previous versions of standard.
Test involves slowly rotating a ring on top of material of choice. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Materials are tested in pairs under nominally non-abrasive conditions.
In this latter case, the results cannot be compared to the ILS data Table 2. Work Item s – proposed revisions of this standard. Stribeck Curve Stribeck curve is a plot between coefficient of friction and bearing number. The test setup allows dni mount real pieces of actual piston ring and liners.
The standard Test to determine extreme pressure, friction wear properties of lubricant greases, solid bonded films, gear and hydraulic fluids, lubricating oils. Real time down force controlpiezo sensors to measure inline friction makes this module very reliable and repeatable.
Linear Oscillating The standard Test to determine extreme pressure, friction wear properties of lubricant greases, solid bonded films, gear and hydraulic fluids, lubricating oils. 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. The tests can be done in controlled environmental conditions including humidity, 503244 and more.
The value of any wear test method lies in predicting the relative ranking of material combinations. Tapping Torque, Twist Compression, Drilling Tapping torque module allows to characterize friction, wear, torque etc. Twist Compression is designed to measure friction and adhesion in metal forming.
