30、 All rights reserved ISO 4649:2017(E)IntroductionVarious types of laboratory test equipment for wear resistance of rubber compound have been developed depending on the products to which rubber compounds have been applied in the past. Methods and equipment are briefly introduced in ISO 23794 and the
31、test method using a rotating cylindrical drum device is described in detail in this document.Because factors such as the grade of abrasive sheet, the type of adhesive used in the manufacture of the sheet and contamination and wear caused by previous testing lead to variations in the absolute values
32、of abrasion loss, all tests are comparative. Runs with a reference compound are included so that the results can be expressed either as a relative volume loss compared to a calibrated abrasive sheet or as an abrasion resistance index compared to a reference compound.This document describes two metho
33、ds and specifies two standard reference compounds that can be chosen freely, although some combinations are more frequently used in practice. Considerable experience has been accumulated using the relative volume loss calculation in 10.2 for method A with reference compound no. 1 and method B with r
34、eference compounds no. 1 and no. 2.When using standard reference compound no. 1 with a non-rotating test piece, a very important part of the method is the preparation of the abrasive sheet and its calibration.Relative volume loss can be calculated for either test method with another reference compou
35、nd, if the defined mass loss is known.

Reference should be made to appropriate documentation on safe handling and disposal after use.1 ScopeThis document specifies two methods for the determination of the resist
38、ance of rubber to abrasion by means of a rotating cylindrical drum device.The methods involve determination of the volume loss due to the abrasive action of rubbing a test piece over a specified grade of abrasive sheet. Method A is for a non-rotating test piece and method B is for a rotating test pi
39、ece. For each method, the result can be reported as a relative volume loss or an abrasion resistance index.These test methods are suitable for comparative testing, quality control, specification compliance testing, referee purposes and research and development work. No close relation between the res
40、ults of this abrasion test and service performance can be inferred.NOTE The abrasion loss is often more uniform using the rotating test piece because the whole surface of the test piece is in contact with the abrasive sheet over the duration of the test. However, there is considerable experience usi
41、ng the non-rotating test piece.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
