Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

General friction testing precautions are citedand a prescribed method of recording friction data is recom-mended. Their use will significantly reduce the need for each laboratory to do its own testing.

ASTM G115-10.pdf

In this case an elastic frictionmeasuring system would be appropriate. Friction Wear Force Abrasive Shoe. No other gg115 of measurement are included in this standard. Please download to get full document.

If an g115 involves materialssuch as friction composites, one of the brake type dynamom-eter tests may be appropriate. We are nonprofit website to share and download documents. When pulling a steelcable over the same roll, it would be more appropriate to use astiff testing system. It is hoped that the use of a uniform reporting format will provide the basis for the preparation of handbooks and computerized databases. Standard Costing Jul 25, Requirements for minimum data and a format for present-ing these data are suggested.


To the running of this website, we need your help to support us. We are always happy to assist you. The overall goal of this guide is to provide a reporting format that will enable computer databases to be readily established. Sufficient information on g1115 conditions will be available to determine applicability of the friction data to the engineer’s specific needs.

Standard Guide for Measuring and Reporting Friction Coefficients

The overall goal of this guide is to provide a reporting formatthat will enable computer databases to be readily established. Test surfaces that are prone to blocking or interlock-ing of surface features v115 particularly prone to showing abreakaway force spike.

A number in parentheses indicates the year of last reapproval. 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.

ASTM G – 04 Standard Guide for Measuring and Reporting Friction Coefficients

G 40 — These databases can be aatm for material couples and tribosystems of interest. Any of the listed tests or other acceptedtests may be used. Originallypublished as G – Asuperscript epsilon e indicates an editorial change since the last revision or reapproval.

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. It is hoped that the use of auniform reporting format will provide the basis for the prepa-ration of handbooks and computerized databases. Last previous edition G – 93 e 1. Current edition approved October 10, We Need Your Support.

Each triboelementcontains one or more tribosurfaces. Weartest machines are often equipped with sensors to measurefriction forces also.

It is v115 responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Historical Version s – view previous versions of standard. Blocking is a term used to describe thetendency of some plastic materials to stick to each other afterlong periods of contact. These databases can be searched for material couples andtribosystems of interest.

G 40— 93 3. This breakaway force is commonlyused to calculate static friction Fig.

The appropriate device to use is the onethat closely simulates a tribosystem of interest. Requirements for minimum data and aztm format for presenting these data are suggested.

The usual manifestation is a cycling decrease andsubsequent increase in the friction force as sliding proceeds Fig. This guide is intended to promote the use of thisstandard reporting system and standard friction test methods.
