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 two cases
The first case is the case where the preservative treated wood is not covered and not in contact with the ground or
the water. There are two situations in this case where emissions could enter the environment:
1) emissions from preservative treated wood stored outside in the storage yard of a preservative treatment
site. Rain falling on the treated wood could produce emissions which run off into surface water and/ or
soil;
2) emissions from treated wood used in commodities exposed in Use Class 3. This is the situation in which
the wood or wood-based product is not covered and not in contact with the ground. It is either continually
exposed to the weather or is protected from the weather but subject to frequent wetting. Use classes are
defined in EN 335-1 and categorise the biological hazard to which the treated commodity will be
subjected. The Use Classes also define the situation in which the treated commodity is used and
determine the environmental compartments (air, water, soil) which are potentially at risk from the
preservative treated wood. Rain falling on treated wood in Use Class 3 could produce emissions that run
off into surface water and/ or soil.
The second case is the case where the preservative treated wood is not covered and is in contact with the ground,
fresh water or sea water. There are three situations in this case where emissions could enter the environment:
3) Emissions from preservative treated wood in contact with the ground. Use Class 4A. Emissions from the
surface of the treated wood could enter the soil via the soil water.
4) Emissions from treated wood in contact with fresh water. Use Class 4B. Emissions from the surface of the
treated wood could enter the water.
5) 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 methods are laboratory procedures for obtaining water samples (emissate) from treated wood exposed out of
ground contact and treated wood exposed in contact with ground, surface water or sea water, at increasing time
intervals after exposure. The quantities of emissions in the emissate are related to the surface area of the wood
and the length of exposure, to estimate a flux in milligrams per square meter per day. The flux after increasing
periods of exposure (e.g. 1 year, 10 years) can be estimated. The emissate can also be tested for ecotoxicological
effects
The quantity of emissions can be used in an environmental risk assessment of the treated wood.

1 Scope
This Technical Report specifies two laboratory methods for obtaining water samples: one from preservative treated
wood exposed out of ground contact (wood held in the storage yard after treatment and Use Class 3) and the other
from treated wood which has been in continuous contact with ground or water (Use Class 4 or 5), at increasing
time intervals after exposure.
2 Method for wood held in the storage yard after treatment and for wooden
commodities exposed in Use Class 3 (not covered, not in contact with the ground)
2.1 General considerations
The principal agent for causing emissions from wood during open-air storage in the yard and in Use Class 3 is
rainfall. Wood exposed in above ground situations is subjected to the intermittent wetting of rainfall and the drying
of the wood surface between the rainfall events. This wetting and drying cycle is simulated in this document. It is
assumed that emissions obtained by exposure to rainfall are identical to emissions obtained by immersion in 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 test can be applied to wood treated using a penetrating process or superficial application, and to wood which
has an additional surface treatment (e.g. paint).
The wood samples used shall be representative of the commodities used.
The composition, amount, pH value and the physical form of rainfall is important in determining the quantity,
content and nature of emissions from wood. However, simulating a realistic rainfall regime in the laboratory is time-
consuming, expensive and is likely to lack reproducibility, accuracy, precision and reliability. This method uses a 1
min immersion in water to simulate exposure to a rainfall event. There are three rainfall events per day and days of
rainfall events are separated by at least two days without rainfall events.
The duration of the test shall be sufficient to enable a flux profile against time to be determined, (e.g. time
necessary to reach steady state or maximum of 30 days) to allow extrapolations of flux for longer periods (e.g. 1
year, 10 years and more).
2.2 Principle
For obtaining water samples from treated wood exposed out of ground contact, at increasing time intervals after
exposure, preservative treated wood test specimens are immersed in water for 1 min. The mass of water taken up
by the test specimen is equivalent to 720 mm of rain per year. The test specimen is allowed to dry between
immersions, simulating the wetting and drying cycle of natural exposure situations. Immersion is repeated at
intervals over at least 30 days. The water (emissate) is collected and chemically analysed or tested for ecotoxicity
at seven or more sample times over the 30 days. Tests with untreated samples can be discontinued if there is no
background detected in the first three data points Emission rates in milligrams per square meter per day are
calculated from analytical results.
A system with untreated wood specimens provides background levels for emissates from wood.
2.3 Product and reagent
2.3.1 Water
Deionized water is recommended. The pH value of the water shall be in the range 5 to 7. The pH value shall not be
adjusted unless special conditions might justify setting the pH value to a specified value, between 5 and 7.
NOTE 1 Water complying with grade 3 of EN ISO 3696 is ideal but not necessary.

NOTE 2 Artificial rain, according to other OECD test guidelines, can be used.
Water temperature shall be (20 ± 2) °C and the measured pH value and water temperature shall be stated in the
test report.
2.3.2 Preservative
The identity of the preservative product for treatment 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) with a generic
description of the co-formulants (e.g. cosolvent, resin), and the composition in mass fraction of the ingredients.
2.4 Apparatus
2.4.1 Immersion container
The container is made of an inert material and is 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 specimen to
2 -3 2 -3
the volume of water to which it is exposed, to be 40 (i.e. 40 m x m or 0,4 cm x cm ).
NOTE For example, for five wood test specimens 25 mm wide by 50 mm long, 15 mm thick, end sealed, where the
2
surface area exposed to water is 200 cm the volume of water required is 500 ml.
2.4.2 Assembly for test specimens
The test specimens are supported on an assembly which exposes all of the exposed surfaces of the test
specimens to contact with water
2.5 Test specimens
2.5.1 Species of wood
The wood species shall be typical of the wood species used for the efficacy testing of wood preservatives e.g.
Pinus sylvestris (Linnaeus) (Scots pine).
NOTE Additional tests may be made using other species but, if so, this should be stated in the test report.
2.5.2 Quality of wood and wood moisture content
Use straight grained wood without knots. Material of a resinous appearance shall be avoided.
NOTE The wood should be typical of wood which is available commercially.
The source, density and number of annual growth rings per 10 mm shall be stated in the test report.
2.5.3 Size of test specimens
Wood test specimens have minimum dimensions of 25 mm wide by 50 mm in length, 15 mm thick, with the
longitudinal faces parallel to the grain of the wood. Test specimens shall consist of 100 % sapwood. Each test
specimen is marked so that it can be identified throughout the test.
The wood test specimens shall be "plain" sawn and the surfaces shall not be sanded.
2.5.4 Number of test specimens
Two sets of treated test specimens in two immersion containers (2.4.1) are used and the mean value taken as the
emission value. One set of untreated test specimens in one immersion container is also used. The number of wood
test specimens depends on the specimens size. The total surface of wood test specimens to be immersed in one
2
immersion container is at least 200 cm , and the minimum number of test specimens per immersion container is
three. For one test there is at least nine (three sets of three) test specimens: six test specimens are treated with
preservative, three test specimens are untreated. Sufficient test specimens are prepared to allow selection of six

which are within 5% of the mean value of the retentions of the group of test specimens, and one for the estimation
of the oven dry moisture content of the test specimens before treatment.
2.5.5 End seal
The wood test specimens are end sealed with a substance which prevents penetration of preservative into the test
specimens.
NOTE Two coats of a silicone sealant have been found to be suitable.
2.6 Procedure
2.6.1 General
The test shall be carried out in a room which has a temperature of (20 ± 2) °C. The air humidity of the laboratory
shall also be monitored.
2.6.2 Preparation of the treated test specimens
