All tests are done in oscillation mode under controlled environmental conditions. Work Item s – proposed revisions of this 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. The test involves rotating one ball on three stationary balls at controlled environmental conditions. The value of any wear test method 500324 in predicting the relative ranking of material combinations. 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.

In all modules listed above user can change the load and velocity to automatically plot Stribeck Curves with ease. Twist Compression is designed to measure friction and 503324 in metal forming. The tests can be done in controlled environmental conditions including humidity, temperature and more. Contact us for a live Demo or additional information. High-load and high-temperature tribometer dun Such a use of this standard is encouraged as a means to improve wear testing methodology. Thank you for your interest and filling out the form!

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Stribeck Curve Stribeck curve is a plot between coefficient of friction and bearing number. Tapping Torque, Twist Compression, Drilling Tapping torque module allows to characterize friction, wear, torque etc. Fast Exchange makes all these modules easily swapable on the MFT platform. Temperature and recirculation addons are also available. 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 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. The coefficient of friction may also be determined. The test setup allows to mount real pieces of actual piston ring and liners. 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. Historical Version s – view previous versions of standard. Cara hack email yahoo tanpa password managers login.

High-load and high-temperature tribometer – Fraunhofer IST The principal areas of experimental attention in using this type of apparatus to measure wear are described. No other units of measurement are included in this standard. The ball is caused to rub against the disk 1mm stroke at a frequency of 50 Hz for 75 min. Real time down force controlpiezo 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. Fin are tested in pairs under nominally non-abrasive conditions. Piston Ring Liner This test helps evaluate friction and wear parameters of piston ring liner material in presence of engine oils.

In this latter case, the results cannot be compared to the ILS data Table 2. Loads from mN to 10,N. However, it must be clearly stated in any report that, while the directions and protocol in Test Method G99 di followed if truethe choices of test parameters were different from Test Method G99 values, and the test results were ein also different from the Test Method G99 results.
