These databases can be searched for material couples andtribosystems of interest. G 40— 93 3. 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. Sufficient information on test conditions will be available to determine applicability of the asgm data to the engineer’s specific needs. To the running of this website, we need your help to support us.

Plasticizer migration can be the cause. Friction Wear Force Abrasive Shoe. Test surfaces that are prone to blocking or interlock-ing of surface features are particularly prone to showing abreakaway force spike. We are always happy to assist you. It is hoped that the use of astn reporting format will provide the basis for the prepa-ration of handbooks and computerized databases. 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.

ASTM G – 10() Standard Guide for Measuring and Reporting Friction Coefficients

Originallypublished as G – This guide is intended to promote the use of thisstandard reporting system and standard friction test methods. No t115 units of measurement are included in this standard. All materials on our website are shared by users. The overall goal of this guide is to provide a reporting formatthat will enable computer databases to be readily established.

Requirements for minimum data and a format for present-ing these data are suggested. Weartest machines are often equipped with sensors to measurefriction forces also.

G115 Current version: If you have any questions about copyright issues, please report us to resolve them. Asuperscript epsilon e indicates an editorial change since the last revision or reapproval.

These databases can be searched for material couples and tribosystems of interest.

It is the responsibility of the user of this standard to establish appropriate safety, health, and qstm practices and satm the applicability of regulatory limitations prior to use. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Summary of Guide 4. Each triboelementcontains one or more tribosurfaces. The usual manifestation is a cycling decrease andsubsequent increase in the friction force as sliding proceeds Fig. Link to Active This link will always route to the current Active version of the standard.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. If an application involves materialssuch as friction composites, one of the brake type dynamom-eter tests may be appropriate.

Any of the listed tests or other acceptedtests may be used. It astk hoped that the use of a uniform reporting format will provide the basis for the preparation of handbooks and computerized databases. Other important factors to simulate arenormal force contact pressurevelocity, type of motion reciprocating versus unidirectional and environment.

A number in parentheses g115 the year of last reapproval. Their use will significantly reduce the need for each laboratory to do its own testing. Please download to get full document.

Blocking is a term used to describe thetendency of some plastic materials to stick to each other afterlong periods of contact. Historical Version s – view previous versions of standard.

General friction testing precautions are citedand a prescribed method of recording friction data is recom-mended. When pulling a steelcable over the same roll, it would be more appropriate to use astiff testing system. The appropriate device to use is the onethat closely simulates a tribosystem of interest. Standard Costing Jul aztm, Requirements for minimum data and asmt format for presenting these data are suggested. Last previous edition G – 93 e 1.

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. This breakaway force is satm to calculate static friction Fig.
