Requirements for minimum data and a format for present-ing these data are suggested. Historical Version s – view previous versions of standard. 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 y115 between laboratories. These databases can be searched for material couples andtribosystems of interest. No other units of measurement are included in this standard.

This guide is intended to promote the use of 1g15 reporting system and standard friction test methods.

This breakaway force is commonlyused to calculate static friction Fig. Asuperscript epsilon e indicates an editorial change since the last revision or reapproval.

We Need Your Support. The overall goal of this guide is to provide a reporting formatthat will enable computer databases to be readily established. It is hoped that the use of a uniform reporting format will provide the basis for the preparation of handbooks and computerized databases.

In this case f115 elastic frictionmeasuring system v115 be appropriate. Please download to get full document. Weartest machines are often equipped with sensors to measurefriction forces also.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. G 40 — Current edition approved October 10, The overall goal of this guide is to provide a reporting format that will enable computer databases to be readily established.

It is hoped that the use of auniform reporting format will provide the basis for the prepa-ration of handbooks and computerized databases. Any of the listed tests or other acceptedtests may be used.

Each triboelementcontains one or more tribosurfaces. Thank you for ashm our website and your interest in our free products and services. Sufficient information on test conditions will be available to determine applicability of the friction data to the engineer’s specific needs.

Summary of Guide 4. These databases can be searched for material couples and tribosystems of interest. When pulling a steelcable over the same roll, it would be more appropriate to use astiff testing system.

G 40— 93 3. 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. Other important factors to simulate arenormal force contact pressurevelocity, type of motion reciprocating versus unidirectional and environment.

General friction testing precautions are citedand a prescribed method of recording friction data is recom-mended. Test surfaces that are prone to blocking or interlock-ing of surface features are particularly prone to showing abreakaway force spike.

A number in parentheses indicates the year of last reapproval.
