It is hoped that the use of auniform reporting format will provide the basis for the prepa-ration of handbooks and computerized databases.
Weartest machines are often equipped with sensors to measurefriction forces also. In this case an elastic frictionmeasuring system would be appropriate.
Thank you for visiting our website and your interest in our free products and services. Test surfaces that are prone to blocking or interlock-ing of surface features are particularly prone to showing abreakaway force spike. This breakaway force is commonlyused to calculate static friction Fig.
A number in parentheses indicates the year of last reapproval. We are nonprofit website to share and download documents. In addition, elastic beams containing straingages may produce different friction responses than a more rigid load celleven if used on the same friction testing machine.
Link to Active This link will always route to the current Active version of the standard. Asuperscript epsilon e indicates an editorial change since the last revision or reapproval.
This guide is intended to promote the use of thisstandard reporting system and standard friction test methods. Their use will significantly reduce the need for each laboratory to do its own testing. These databases can be searched for material couples and tribosystems of interest.
ASTM G – 04 Standard Guide for Measuring and Reporting Friction Coefficients
All materials on our asym are shared by users. The use of the suggested reporting form will increase the long-term usefulness of the test results within a given laboratory and will facilitate the exchange of test results between laboratories.
General friction testing precautions are citedand a prescribed method of recording friction data is recom-mended.
To the running of this website, we need your help to support us. G 40 — We are always happy to assist you. Sufficient information on test conditions will be available to determine applicability of the friction data to the engineer’s specific needs.
Standard Costing Jul 25, G 40— 93 3. Historical Version s – view previous versions of standard. We Need Your Support.
The appropriate device to use is the onethat closely simulates satm tribosystem of interest. When pulling a steelcable over the same roll, it would be more appropriate to use astiff testing system. Requirements for minimum data and a format for presenting these data are suggested.
Blocking is a term used to describe thetendency of some plastic materials to stick to each other afterlong periods of contact.
If you have any questions about copyright issues, please report us to resolve them. It is hoped that the use of a uniform reporting format will provide the basis for the preparation of handbooks and computerized databases. These databases can be searched for material couples andtribosystems of interest. Each triboelementcontains one or more tribosurfaces.
Standard Guide for Measuring and Reporting Friction Coefficients
The overall goal of this guide is to provide a reporting format that will enable computer databases to be readily established. Any of the listed tests or other acceptedtests may be used. Current edition approved October 10, April Current version:
