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.

SIST-TP CEN/TR 15119:2008
CEN/TR 15119:2005 (E)
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

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

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

The wood test specimen to be treated with the preservative under test is treated by the method specified for the

preservative, which can be by a penetrating treatment process or a superficial application process, which may be a

dip, spray or brush.
2.6.3 Treatment process
Penetrating treatment process

Prepare a solution of the preservative, which will achieve the specified uptake or retention when applied using the

penetrating treatment process. Weigh the wood test specimen and measure its dimensions. Carry out the

penetrating treatment process. The process shall be as specified for the application of the preservative to wood out

of ground contact. Weigh the test specimens after treatment. Calculate the retention of the preservative (in

kilograms per cubic meter) from the equation:
m −m w
2 1
x (1)
V 100
where
m is the mass before treatment, in kilograms;
m is the mass after treatment, in kilograms;
w is the solution concentration (mass fraction);
V is the volume of test specimen in cubic meters.

NOTE Timber treated in an industrial treatment plant (e.g. by vacuum pressure impregnation) may be used in this test.

A description of the procedures used shall be stated in the test report.
2.6.3.1 Superficial application processes

Carry out the superficial application process e.g. dip, spray or brush, to the wood test specimens. The process and

application rate (e.g. litres per square meter) shall be as specified for the superficial application of the preservative.

The procedures used, and the application rate or uptake shall be stated in the test report.
