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.
ISO 15181-2 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9,
General test methods for paints and varnishes.
This second edition cancels and replaces the first edition (ISO 15181-2:2000), which has been technically
revised.
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
⎯ Part 3: Calculation of the zinc ethylene-bis(dithiocarbamate) (zineb) release rate by determination of the
concentration of ethylenethiourea in the extract
⎯ Part 4: Determination of pyridine-triphenylborane (PTPB) concentration in the extract and calculation of
the release rate
⎯ Part 5: Calculation of the tolylfluanid and dichlofluanid release rate by determination of the concentration
of dimethyltolylsulfamide (DMST) and dimethylphenylsulfamide (DMSA) in the extract

ISO 15181-2:2007(E)
Introduction
By using standard conditions of temperature, salinity and pH at low biocide concentrations in the surrounding
artificial seawater, a repeatable value of the release rate under the specified laboratory conditions can be
determined using the method given in this part of ISO 15181, which can be used for quality assurance and
material selection purposes. The actual release rate of biocides from antifouling paints on ships' hulls into the
environment will, however, 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.
The results of this test do not reflect environmental biocide release rates for antifouling products and are not
suitable for direct use in the process of generating environmental-risk assessments, producing environmental-
loading estimates or for establishing release rate limits for regulatory purposes. In comparison with copper
and organotin release rates obtained either by direct or indirect measurements of the 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 generic test method significantly overestimate the release rates of biocides under
in-service conditions. Published results demonstrate that the results of this test method are generally higher
than direct in situ measurements of copper and organotin release rates from in-service ship hulls by a factor of
[1, 2]
about 10 or more for several commercial antifouling coatings . A similar relationship is expected to be
found for other biocides. Realistic estimates of the biocide release rate from a ship’s hull under in-service
conditions can only be obtained from this test method if this difference is taken into account.
Where the results of this test 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 laboratory release rates and actual environmental inputs be taken into account to
allow a more accurate estimate of the biocide release rate from antifouling coatings under real-life conditions
[2]
to be obtained. This can be accomplished through the application of appropriate correction factors .

INTERNATIONAL STANDARD ISO 15181-2:2007(E)

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 specifies the apparatus and analytical method for determining the amount of copper
(based) biocide that has been released from an antifouling paint into artificial seawater in accordance with the
procedure given in ISO 15181-1.
It determines the copper-ion concentration and gives the final calculation for the release rate of copper under
the specified laboratory conditions. This part of ISO 15181 is designed to generally allow the concurrent
determination of copper ions and other biocides that might be released by a given antifouling paint through the
analysis of separate sub-samples of an artificial seawater extract generated in accordance with the procedure
given in ISO 15181-1, and analysed in accordance with the procedures given in other parts of this
International Standard.
When used in conjunction with ISO 15181-1, the practical limits on the quantitative measurement of release
–2 –1 –2 –1
rates by this method are from 1,8 µg⋅cm ⋅d to 500 µg⋅cm ⋅d . The quantitative measurement of release
rates below this range will require the use of an analytical method with a lower limit of quantitation for copper
in artificial seawater than the limit specified in 5.1.

in Substitute Ocean Water
3 Principle
The concentration of the copper ions released into artificial seawater in accordance with the procedure given
in ISO 15181-1 is determined by the use of an atomic absorption spectrometer or by an alternative analytical
method, provided that it demonstrates a limit of quantitation for copper in artificial seawater of 10 µg/l or less.
The release rate of the biocide is then calculated as copper metal.
