Foreword

This Standard was drafted in accordance with the rules given in GB/T 1.1-2020

"Directives for standardization - Part 1: Rules for the structure and drafting of

standardizing documents".

This Standard uses translation method to identically adopt ISO 23233:2016 "Rubber,

vulcanized or thermoplastic - Determination of resistance to abrasion using a driven,

vertical abrasive disc".

The Chinese documents which have consistency with the international normative

references in this Standard are as follows:

- GB/T 2481.1-1998, Bonded abrasives - Determination and designation of grain

size distribution - Part 1: Macrogrits F4 to F220 (eqv ISO 8486-1:1996);

MOD);

- GB/T 2941-2006, Rubber - General procedures for preparing and conditioning test

pieces for physical test methods (ISO 23529:2004, IDT).

This Standard made the following editorial modifications:

- Changed the standard name to "Rubber, vulcanized or thermoplastic -

Determination of resistance to abrasion - Driven, vertical abrasive disc method";

- Included the content of the amendment of ISO 23233:2016/AMD1:2017.

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

the subject of patent rights. The issuing authority shall not be held responsible for

identifying any or all such patent rights.

This Standard was proposed by China Petroleum and Chemical Industry Federation.

1 Scope

This Standard describes a method for determining the abrasion resistance of rubber with

a vertically driven abrasive disc.

The wheel-shaped rubber specimen and the grinding disc are perpendicular to each

other and are pressed against each other according to the set load. Abrasion mass loss

is determined by setting different slip angles, rotational speeds and certain loads

between the wheel-shaped specimen and the grinding disc for slippage. Test results are

expressed in terms of mass loss per unit run distance and/or abrasion resistance index

compared to a reference compound.

This document applies to comparative testing, quality control, normative compliance

testing, arbitration testing, and R&D work.

Since the test device can independently set various wear parameters, such as: slip angle,

grinding disc rotation speed and load, this method can be widely used in the wear test

of various rubber products (especially tires).
