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 15181-1 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

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.

INTERNATIONAL STANDARD ISO 15181-1:2000(E)
Paints and varnishes — Determination of release rate of biocides
from antifouling paints —
Part 1:
General method for extraction of biocides
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 a general method for extracting biocides from paint films of antifouling paints into a
specified artificial seawater under specified conditions. It is used in conjunction with ISO 15181-2 to determine the
amount of copper biocides in the extract and allow the calculation of the release rate of the biocide from the paint film.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
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
Test cylinders painted with antifouling paint and reference cylinders are immersed in flowing artificial seawater in a
holding tank. At specified time intervals the cylinders are removed and exposed for a defined period in individual re-
lease rate measuring containers containing the same artificial seawater before being replaced in the holding tank.
The concentration of the biocide released into the water of the individual release rate measuring containers can then
be determined. This operation is repeated at defined time intervals and hence the release rate of the biocide can be
calculated.

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.
5 Apparatus, equipment and reagents
5.1 Test cylinder, made of an inert material (polycarbonate has been found suitable) of diameter (65� 5) mm,
watertight-closed at both ends, of sufficient length to allow the application of the antifouling paint (7.3) and allow at-
tachment to the rotating device (5.2).
5.2 Rotating device, capable of rotating a test cylinder (5.1) in the centre of the release rate measuring container
(5.3) such that the rotational speed of the outside of the test cylinder through the artificial seawater is (60� 5) r/min
[(0,2� 0,02) m/s]. The device itself shall not be allowed to come into contact with the artificial seawater (5.6).
5.3 Release rate measuring container (see Figure 1), made of an inert material (polycarbonate has been found
suitable) of nominal capacity (2� 0,2) litres, 120 mm to 150 mm diameter and 170 mm to 210 mm high. The con-
tainer shall be fitted with three evenly spaced baffles around the inside of the container to prevent swirling during test
cylinder rotation. The baffles consist of circular rods of 4mm to 8mm diameter, made of the same material, which
shall run from the bottom of the container to a level at least 10 mm above that of the artificial seawater. They are fixed
using an inert adhesive or solvent. There shall be a means of maintaining the container and its contents at
�
(25� 1) C.
NOTE Placing the container in a thermostatically controlled water bath has been found to be a suitable means of maintaining the
temperature at the correct level; alternatively the test may be performed in a conditioned room at the specified temperature.

5.4 Holding tank, made of an inert material (polycarbonate has been found suitable) of such dimensions as to per-
mit the immersion of at least four test cylinders. The tank shall be equipped with a system to circulate the artificial
seawater continuously through a filter/pump unit [see annex A, item A.2 g)] (see note) so that the concentration of the
biocide remains below the specified limit [see annex A, item A.2 l)]. The size and positioning of the inlet and outlet
ports shall be such as to obtain a slow and relatively uniform flow of artificial seawater past all the immersed cylin-
ders. In general there shall be between six to eight changes of artificial seawater per hour. There shall be a means of
