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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 7784 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 7784-3 was prepared by Technical Committee ISO/TC 35, Paints and varnishes,
Subcommittee SC 9, General test methods for paints and varnishes.
ISO 7784 consists of the following parts, under the general title Paints and varnishes — Determination of
resistance to abrasion:
� Part 1: Rotating abrasive-paper-covered wheel method
� Part 2: Rotating abrasive rubber wheel method
� Part 3: Reciprocating test panel method
Annex A forms a normative part of this part of ISO 7784. Annex B is for information only.

Introduction
This document is one of three parts of ISO 7784 dealing with determination of resistance to abrasion of a dried film
of paint, varnish or related product.
Parts 1 and 3 both specify a method using abrasive paper for determination of the resistance to abrasion. In part 2,
a method using rubber wheels is described. The user of ISO 7784 should note that the methods using abrasive
paper (parts 1 and 3) are the preferred methods.

Reciprocating test panel method
1 Scope
This part of ISO 7784 is one of a series of standards that deals with the sampling and testing of paints, varnishes
and related products.
It specifies a method of determining the resistance to abrasion of a dried film of paint, varnish or related product by
rubbing the film against a strip of abrasive paper attached to a stationary wheel.

3Principle
A dried paint or varnish film on a test panel is abraded, under specified conditions, by rubbing the panel against a
strip of abrasive paper attached to the circumference of a stationary wheel. The wheel is weighted so that the
abrasive paper is pressed against the panel with a specified force. After each complete reciprocating movement
(double stroke, DS) of the panel, the wheel is advanced through a small angle to bring an unused portion of the
abrasive strip into contact with the test surface.

Either the resulting loss in mass of the test panel is measured after a specified number of double strokes, and the
loss in mass for one double stroke (mg/DS) and the abrasion resistance (DS/mg) are calculated, and/or the mean
number of double strokes required for wearthrough of the coating (or the topcoat of a multicoat system) is
determined (see clause 9).
