Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 28080:2011), which has been technically

revised.
The main changes compared to the previous edition are as follows:
— Clause 2, the normative references have been updated;
— Clauses 3 and 4 have been switched;
— 5.4.1, second sentence: "or neoprene" has been added.

ISO 28080:2021(E)
Introduction

This document provides new and improved methods for testing the abrasion characteristics of

hardmetals using rotating-wheel systems. There are a number of abrasion test methods that have

been developed that use this type of geometry, including the ASTM G65 dry sand/rubber wheel test,

the ASTM G105 wet sand/rubber wheel test and the ASTM B611 steel wheel test. Other variants of

these tests have also been developed for specific applications in other institutes. All of these tests use a

rotating wheel pressed against a test piece, with abrasive material introduced between the wheel and

the test piece. Because of this fundamental commonality, much of the methodology is the same for the

different tests. However, they do differ in the details of how the abrasive is fed to the interface between

the wheel and the test piece, if the test can be carried out in the presence of fluids, and if the abrasive is

only used once and passes through the test system, or is reused many times.

This document provides framework that brings together the key features of these tests and gives

results that show comparability. It also gives information on their reproducibility and repeatability.

The procedure complements the ASTM G65 method for dry sand/rubber wheel abrasion,

the ASTM B611 method for determining the high stress abrasion of hard materials, and the

ASTM G105 method for conducting wet sand/rubber wheel abrasion tests.

Abrasion wear is not a measure of the wear characteristics of hardmetals under all conditions, and

should not be misinterpreted as indicating wear when hardmetals are used for tooling, such as cutting

and milling. It does show the difference in resistance to abrasive use for different carbide compositions,

and the methods may be used as practical tests or as research methods for material discrimination.
