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 not
covered and 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 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;
b) emissions from treated wood in contact with fresh water. Use Class 4B. 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 (emissate) from treated wood in contact
with water, at increasing time intervals. 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 metre per day. The
flux after increasing periods of exposure (e.g. 1 year, 10 years) can be estimated.
NOTE The emissate can also be tested for eco-toxicological effects.
The quantity of emissions can be used in an environmental risk assessment of the treated wood.

1 Scope
This Technical Specification specifies a laboratory method for obtaining water samples from treated wood
which has been in conditions designated to simulate continuous contact with the ground or with water (Use
Class 4 or 5), at time intervals after exposure.
2 Description of the test method
2.1 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 identical in nature and severity to leaching
from a wood surface in continuous contact with water.
The mechanism of leaching at the wood surface by fresh water is assumed to be identical in nature and
severity to leaching from a wood surface by seawater.
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 wood samples used shall be representative of the commodities used.
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.
Water samples will be taken at a minimum interval of one day and a maximum interval of 7 days, on a
sampling scheme covering at least 19 days.
2.2 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 is equivalent to the ratio found in wood exposed in
3 2 2
service in some Use Class 4 situations (1 m per 40 m or 25 l per m ). The water (emissate) is collected and
is chemically analysed at seven or more sample times over the 19 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
2.3 Product and reagent
2.3.1 Water
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.

CEN/TS 15119-2:2008 (E)
2.3.2 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 defined in the EU Directive 98/8/EC) or a generic description of co-
formulants and the composition expressed in terms of the mass fraction of each of the ingredients.
2.4 Apparatus
2.4.1 Immersion container
The container shall be made of a material that is inert to water and the treated timber and 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 the volume of water to which it is exposed, to be 40
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 surface
3 2
area of the test specimen (this is equivalent to 2,5 cm per 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
No equipment used to hold the test specimens below the level of the water shall be made of a material that
will react with the water or the treated timber. The test samples should be restrained in a test frame which
allows all 5 test specimens to be manoeuvred simultaneously and which allows free access of water to all
surfaces.
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 tha
