Introduction
The emissions from preservative treated wood to the environment need to be quantified to enable an
environmental risk assessment of the treated wood. This document describes a laboratory method for
the estimation of emissions from preservative treated wood in the case where the preservative treated
wood is in contact with the ground, fresh water or seawater. There are three situations in this case where
emissions could enter the environment:
a) emissions from treated wood in contact with the ground. Use Class 4. Emissions from the surface of
the treated wood could enter the soil via the soil water;
b) emissions from treated wood in contact with fresh water. Use Class 4. Emissions from the surface of
the treated wood could enter the water;
c) emissions from treated wood in contact with sea water. Use Class 5. Emissions from the surface of
the treated wood could enter the sea.
The method is a laboratory procedure for obtaining water samples (leachate) from treated wood in
contact with water, at increasing time intervals (complete duration of 29 days). The quantities of
emissions in the leachate are related to the surface area of the wood and the length of exposure, to
estimate a flux in milligrams per square metre per day.
The quantity of emissions can be used in an environmental risk assessment of the treated wood.
The results of this short-term test can be extrapolated to longer exposure periods using suitable
projection estimation methods.
1 Scope
This document specifies a laboratory method for obtaining water samples from treated wood which has
been in conditions designed to simulate continuous contact with the ground or with water (use Class 4
or 5), at time intervals after exposure.

4 Description of the test method
4.1 General considerations
The principal agent for causing emissions from wood exposed to soil is the soil water. The mechanism of
leaching at the wood surface by the soil water is assumed to be comparable in nature and of equal or
lesser severity to leaching from a wood surface in continuous contact with water.
The mechanism of leaching at the wood surface by the sea water is assumed to be comparable in nature
and of equal or lesser severity to leaching from a wood surface in continuous contact with fresh water.
The wood, in the case of wood treated with a wood preservative, shall be representative of commercially
used wood. It shall be treated in accordance with the preservative manufacturer’s instructions and in
compliance with appropriate standards and specifications. The parameters for the post-treatment
conditioning of the wood prior to the commencement of the test shall be stated.
The composition, amount and pH value of the water used in the test are important in determining the
quantity, content and nature of emissions from wood.
4.2 Principle
Water samples are collected after continuous contact with treated wood at increasing time intervals. To
simulate the emission of wood preservatives from wood that is exposed to continuous contact with water
test specimens are immersed in water and samples of the water are collected at different intervals. The
volume of water relative to the surface area exposed to the water was found to be a suitable ratio to allow
3 2 2
active substances to be adequately analysed (1 m per 40 m or 25 l per m ). The water (leachate) is
collected and is chemically analysed at seven or more sample times over the 29 days; it is suitable for
ecotoxicity testing. Emission rates in milligrams per square metre per day are calculated from analytical
results. The sampling periods are recorded. Tests with untreated samples can be discontinued if there is
no background detected in the first three data points.
4.3 Products and reagents
4.3.1 Water
Fresh water and soil leaching scenarios: Water complying with grade 3 of EN ISO 3696 or water
especially designed for environmental investigations is ideal. Deionised water can also be used. The pH
value shall normally be in the range 5 to 7. The pH value shall not be adjusted unless special conditions
might justify setting the pH to a specified value between 5 and 7.
Water temperature shall be (20 ± 2) °C. The pH value and water temperature shall be stated in the test
report.
4.3.2 Seawater
Seawater leaching scenarios: Synthetic seawater (e.g. ASTM D 1141 Substitute Ocean Water, without
Heavy Metals) is recommended for use in the leaching test when wood exposed to seawater is to be
evaluated. The water temperature shall be (20 ± 2) °C and the measured pH and water temperature
included in the test report.
4.3.3 Preservative
The identity of the preservative product used to treat the wood samples shall be stated in the test report.
It shall state the name and other designation of the preservative, and the trade or common name of the
active ingredient(s), substances of concern (as specified ed in the EU regulation n°528/2012) or a generic
description of co-formulates and the composition expressed in terms of the mass fraction of each of the
ingredients.
4.4 Apparatus
4.4.1 Immersion container
The container shall be made of a material that is inert to water and the treated timber. It shall be large
enough to allow the test specimens to have all their faces exposed to water and to contain sufficient water
for the ratio of the exposed surface area of the test specimens to the volume of water to which it is exposed
2 -3 2 -3 2
(i.e. 40 m × m or 0,4 cm × cm ). The volume of water required is therefore 25 l per m of exposed
3 2
surface area of the test specimen (this is equivalent to 2,5 cm per cm ).
EXAMPLE For example, for five wood test specimen
