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.

Introduction

Antifouling paints are widely used to prevent fouling of ships’ hulls by marine organisms. Effective antifouling technologies are critical to minimise the skin friction of the hull and to maintain the fuel consumption efficiency of ships. The evaluation of antifouling paints is generally undertaken by adopting a tiered approach whereby paint manufacturers use a battery of laboratory tests, patch tests and full vessel trials. Patch tests and full vessel trials are generally conducted over extended periods of time and are predominantly relied upon for the prediction of coating performance when used commercially.

This document deals with a laboratory test to characterize the skin friction of antifouling paints. It does not necessarily represent the actual performance of antifouling paints on application to the ship hull. Therefore, this document does not provide a validated test for predicting the ability of an antifouling paint to minimize the skin friction of the hull.

1 Scope

This document provides a laboratory test method to determine the skin-friction of antifouling paints coated on drums.

The results of the laboratory-tested friction of painted drums over a certain period of time can be used for screening of antifouling paints and characterizing changes in friction for different antifouling paints, amongst other applications and other purposes depending on the user’s need.

This document is applicable to both biocidal-based and biocide-free antifouling paints.
