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 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
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 the temperature, salinity, pH, pollutants and biological community in a particular area. However, based on
knowledge of the composition of the paint and its specified lifetime and application thickness, an estimate of
the mean biocide release rate from an antifouling paint over its specified lifetime can be obtained by the
mass-balance calculation method described in this International Standard. The calculation also allows an
estimate to be obtained of the cumulative mass of biocide released over the first 14 days, and also the total
mass of biocide released over the specified lifetime.
This method is intended to provide estimates of the amount of biocide released into the environment that are
more suitable for use in environmental risk assessments than the results of laboratory-based test methods,
[1] [2] [3]
such as ISO 15181 (all parts) , ASTM D6442 and ASTM D6903 . Biocide release rate data is a key input
to the environmental risk assessment process for antifouling products, and so it is vital that the estimated
biocide release rate that is used be both accurate and representative of the release rate to the environment in
the relevant scenario and risk assessment case. In comparison with in situ biocide release rate values
obtained by either direct or indirect measurements of the organotin and copper release rate from ships' hulls
and from measurements made on panels exposed in harbours, all available data indicate that the results
obtained using this calculation method overestimate the release rates of biocides under environmentally
relevant in-service conditions. Published results demonstrate that the results of this calculation method are
generally higher than direct in situ measurements of copper release rate from the hulls of harboured ships by
[4]
a factor of about 4 or more for several commercial antifouling coatings . A similar relationship is expected to
be found for other biocides. Where the results of this calculation method are used in the process of generating
environmental risk assessments, producing environmental loading estimates or for regulatory purposes, it is
most strongly recommended that the relationship between calculated release rates and actual environmental
inputs be taken into account to allow the most accurate and representative estimate of the biocide release rate
from antifouling coatings under real-life conditions to be obtained. This can be accomplished through the
[4]
application of appropriate correction factors .
