Introduction
The emissions from preservative treated wood into the environment need to be quantified to enable an
environmental risk assessment to be made of the treated wood. This document describes a laboratory method
for the determination of emissions from preservative treated wood 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 such
emissions could enter the environment:
a) 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 that run off into surface water and / or soil;
b) 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 method is a laboratory procedure for obtaining water samples (emissate) from treated wood exposed out
of ground contact, at 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 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 describes a laboratory method for obtaining water samples from preservative
treated wood exposed out of ground contact (wood held in the storage yard after treatment and which has
been in conditions designed to simulate outdoor, out of ground contact situations), at increasing time intervals
after exposure.
2 Description of the test method
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 intermittent wetting by rainfall and drying of
the wood surface between the rainfall events. These wetting and drying cycles are simulated by the method
described in this document. It is assumed that emissions obtained by short-term immersion in water are
indicative of the emissions which will occur during exposure to rainfall.
The wood, in the case of wood treated with a wood preservative, shall be representative of commercially
treated wood. It shall be treated in accordance with the preservative manufacturer’s instructions and in
compliance with appropriate standards and specifications. The parameters for 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, pH value and the physical form of rainfall are 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 and has been developed to give the wood moisture content, which is relative
to a rainfall event. There are three immersions per day and days of immersion are set at 1 days, 3 days, 5
days, 8 days, 10 days, 12 days, 15 days, 17 days and 19 days. This schedule allows sampling 3 times per
week on Monday, Wednesday and Friday.
2.2 Principle
To simulate the emission of wood preservatives from wood exposed to rain water, a simulated wetting and
drying process is employed. At each of the 9 “immersion days” stated in 2.1, the following process is applied :
test specimens are immersed in water for 1 minute and then removed and allowed to dry; this cycle is
repeated three times during an immersion day. This process is used to simulate the wetting and drying of
natural exposure situations. The water (emissate) from each immersion day is collected and analysed
chemically. It is suitable for ecotoxicity testing. Emission rates in milligrams per square metre per day are
calculated from analytical results.
A system with untreated wood specimens provides background levels for emissates from wood. 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.
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) and substances of concern (as defined in the EU Directive 98/8/EC) or a generic description of
co-formulants and the composition of the product 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 per 1m or 0,4 cm × 1cm ). 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 ).
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.
