These databases can be searched for material couples andtribosystems of interest. We Need Your Support. Other important factors to simulate arenormal force contact pressurevelocity, type of motion reciprocating versus unidirectional and environment. Please download to get full document. Asuperscript epsilon e indicates an editorial change since the last revision or reapproval.

Friction Wear Force Abrasive Shoe. Each triboelementcontains one or more tribosurfaces.

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. All materials on our website are shared by users. We are nonprofit website to share and download documents. No other units of measurement are included in this standard. General friction testing precautions are citedand a prescribed method of recording friction data is recom-mended. April Current version: The usual manifestation is a cycling decrease andsubsequent increase in the friction force as sliding proceeds Fig.

The appropriate device to use is the onethat closely simulates a tribosystem of interest. Summary of Guide 4. It is hoped that the use of auniform reporting format will provide the basis for the prepa-ration of handbooks and computerized databases. Originallypublished as G – This guide is intended to promote the use of thisstandard reporting system and standard friction test methods.

Last previous edition G – 93 e 1. Plasticizer migration can be the cause.

Their use will significantly reduce the need for each laboratory to do its own testing. This breakaway force is commonlyused to calculate static friction Fig. Current edition approved October 10, These databases can be searched for material couples and tribosystems of interest.

Requirements for minimum data and a format for present-ing these data are suggested. It is hoped that the use f115 a uniform reporting format will provide the basis for the preparation of handbooks and computerized databases. Weartest machines are often equipped with sensors to atsm forces also.

The overall goal of this guide is to provide a reporting format that will enable computer databases to be readily established.

Standard Costing Jul 25, Blocking is a term used to describe thetendency of some plastic materials to stick to each other afterlong periods of contact. It is the y115 of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Test surfaces that are prone to blocking or interlock-ing of surface features asgm particularly prone to showing abreakaway force spike. When pulling a steelcable over the same roll, it would be more appropriate to use astiff testing system. A number in parentheses indicates the year of g1155 reapproval.
