To the running of this website, we need your help to support us. This breakaway force is commonlyused to calculate static friction Fig.

If an application involves materialssuch as friction composites, one of the brake type dynamom-eter tests may be appropriate. Asuperscript epsilon e indicates an editorial change since the last revision or reapproval. Please download to get full document. 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.

G 40— 93 3. These databases can be searched for material couples andtribosystems of interest. No other units of measurement are included in this standard.

We are always happy to assist you. Any of the listed tests or other acceptedtests may be used.

Historical Version s – view previous versions of standard. Summary of Guide 4. Their use will significantly reduce the need for each laboratory to do its own testing.

Requirements for minimum data and a format for presenting these data are suggested. In addition, elastic beams containing straingages may produce different friction responses than a more awtm load celleven if used on the same friction testing machine.

Thank you for visiting our website and your interest in our free products and services. The appropriate device b115 use is the onethat closely simulates a tribosystem of interest.

G 40 asfm A superscript 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.

The overall goal of this guide is to provide a reporting format that will enable computer databases to be readily established. When pulling a steelcable over the same roll, it would be more appropriate to use astiff testing system. Standard Costing Jul 25, Weartest machines are often equipped with sensors to measurefriction forces also. Last previous edition G – 93 e 1. Ast is hoped that the use of a uniform reporting format will provide the basis for the preparation of handbooks and computerized databases.

Sufficient information on test conditions will be available to determine applicability of the friction data to the engineer’s specific needs. Current edition approved October 10, Test surfaces that are prone to blocking or interlock-ing of surface features are particularly prone to showing abreakaway force spike. Requirements for minimum data and a format for present-ing these data are suggested. General friction testing precautions are citedand a prescribed method of recording friction data is recom-mended.

We Need Your Support. April Current version: Link to Active This link will always route to the current Active version of the standard. These databases can be searched for material couples and tribosystems adtm interest.

In this case an elastic frictionmeasuring system would be appropriate. Plasticizer migration can be the cause. Other important factors to simulate arenormal force contact pressurevelocity, type of motion reciprocating versus unidirectional and environment. Each triboelementcontains one or more tribosurfaces.

It is hoped that the use h115 auniform reporting format will provide the basis for the prepa-ration of handbooks and computerized databases. If you have any questions about copyright issues, please report us to resolve them. Blocking is a term used to describe thetendency of some plastic materials to stick to each other afterlong periods of contact.
