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 com-
mittees. 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 liai-
son 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 15181 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 15181-2 was prepared by Technical Committee ISO/TC 35, Paints and varnishes,Sub-
committee SC 9, General test methods for paints and varnishes.
ISO 15181 consists of the following parts, under the general title Paints and varnishes — Determination of release
rate of biocides from antifouling paints:
— Part 1: General method for extraction of biocides
— Part 2: Determination of copper-ion concentration in the extract and calculation of the release rate
Annexes A and B form a normative part of this part of ISO 15181.

Introduction
By using standard conditions of temperature, salinity and pH at low biocide concentrations in the surrounding artifi-
cial seawater, a repeatable value of the release rate can be determined which can be used for quality assurance,
material selection, environmental regulations or paint comparison purposes. However the actual release rate of
biocides from antifouling paints on ships hulls into the environment will depend on many factors, such as ship
operating schedules, length of service, berthing conditions, paint condition, as well as temperature, salinity, pH,
pollutants and bacterial content.

Paints and varnishes — Determination of release rate of biocides
from antifouling paints —
Part 2:
Determination of copper-ion concentration in the extract and
calculation of the release rate
1 Scope
This part of ISO 15181 is one of a series of standards dealing with the sampling and testing of paints, varnishes and
related products.
This part of ISO 15181 specifies the apparatus and analysis technique for determining copper (based) biocides in
artificial seawater which have been extracted from antifouling paints in accordance with ISO 15181-1. It determines
the copper-ion concentration and gives the final calculation for the release rate of copper. It has been proven that
small changes in certain parameters of the test method can greatly affect the leaching rate of certain biocides, there-
fore, the release rates are compared against a well-documented reference standard as a means of establishing that
test conditions are within normal operating parameters.

this part of ISO 15181. For dated references, subsequent amendments to, or revisions of, any of these publications
do not apply. However, parties to agreements based on this part of ISO 15181 are encouraged to investigate the
possibility of applying the most recent editions of the normative documents indicated below. For undated references,
the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of cur-
rently valid International Standards.

3 Principle
The concentration of the copper ions released into artificial seawater by the method defined in ISO 15181-1 is deter-
mined by the use of an atomic absorption spectrometer or by another agreed instrument which has been shown to
have equivalent or better precision. The release rate of the biocide is then calculated as copper metal.
4 Required supplementary information
For any particular application, the test method specified in this part of ISO 15181 needs to be completed by
supplementary information. The items of supplementary information are given in annex A.
