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 by leaching 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 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 (leachate) from treated wood exposed

out of ground contact, at time intervals after exposure. 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 flux after increasing periods of exposure (e.g. 1 year, 10 years) can be

estimated.
NOTE The leachate can also be tested for eco-toxicological effects.

The quantity of emissions can be used in an environmental risk assessment of the treated wood.

The test can be applied to wood treated using a penetrating process or superficial application (brush,

spray or dipping), or to treated wood which has an additional surface treatment (e.g., paint that is applied

as a requirement for commercial use).

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 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated

references, the latest edition of the referenced document (including any amendments) applies.

EN ISO 5667-3, Water quality — Sampling — Part 3: Preservation and handling of water samples (ISO

5667-3)
3 Description of the test method
3.1 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.
Two main immersion regimes are recommended as follows:

1. The 3 x 1 minute immersion regime: A 1 minute immersion in water of the treated test specimens to

simulate exposure to a rainfall event. There are three immersions or rainfall events per day, with test

specimens allowed to dry for 3 hours between immersions simulating the wetting and drying cycle

of natural exposure situations. The days of rainfall are set for 1, 3, 5, 8, 10, 12, 15, 17 and 19 days.

NOTE 1 The OECD Emission Scenarios for Wood Preservatives 2013 (see bibliography) that are applied for

the authorization procedure of the European BPR are based on the assumptions, that the total amount of

rainfall per year is 700 mm. The daily regime is intended to produce the same moisture content on the surface

of the wood, and the same moisture content profile in the wood, and thus the same emission, as wood in a real

exposure situation on a day during which rain occurs. It is intended that a 3 x 1 minute dip, every third day,

will give the same moisture content cycle in the wood, and the same emission from the wood, as exposure

under real conditions. If the dipping and drying regime is continued for one year, the emission quantity and

rate would be the same as the emission obtained from wood after exposure in a real situation in a region of

Europe where there is 700 mm of rain per year, with rain events occurring on 260 days of the year.

CEN/TS 15119-1:2018 (E)

2. The 2 x 1 hour immersion regime: A 1 hour immersion in water of the treated test specimens to

simulate exposure to a rainfall event. There are two immersions or rainfall events per day, with test

specimens allowed to dry for 4 hours between immersions simulating the wetting and drying cycle

of vertical natural exposure situations. The days of rainfall are set for 1, 3, 5, 8, 10, 12, 15, 17 and 19

days.

The applicant must provide adequate discussion of the conditions of these regimes (e.g., purpose is to

estimate emissions from wood that is treated and then exposed vertically or horizontally) for data to be

acceptable when using these regimes.

NOTE 2 The OECD 107 (see in Bibliography) proposes a third immersion regime (1 x 2 hours). It was decided

not to retain this option in the European standard.
3.2 Principle

To simulate the emission of wood preservatives from wood exposed to rain water, a simulated wetting

and drying process is employed. This process is used to simulate the wetting and drying of natural

exposure situations. The water (leachate) 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 leachates from wood. Tests

with untreated samples can be discontinued if there is no background detected in the first three data

points.
3.3 Quality criteria
3.3.1 Accuracy

The performance of the analytical method should be determined before conducting the test:

1) Accuracy;
2) Specificity;
3) Limit of detection;
4) Limit of quantification.
The testing is carried out with untreated references and with controlled water.

NOTE EN ISO 5667-3 may give guidance on the preservation and handling of water samples.

3.3.2 Reproducibility

Two water samples are collected and analysed and the mean value is taken as the emission value. The

reproducibility of the results within one laboratory and between different laboratories depends upon the

immersion regime and the wood used as test specimens.
3.4 Product and reagent
3.4.1 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.
---------------------- Page: 8 ----------------------
SIST-TS CEN/TS 15119-1:2018
CEN/TS 15119-1:2018 (E)
Water temperature shall be (20 ± 2) °C.
The pH value and water temperature shall be stated in the test report.
3.4.2 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 Biocidal Products Regulation

No.528/2012) 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.
3.5 Apparatus
3.5.1 Immersion container

The container shall be made of a material that is inert to water, treated wood and any substance that is

to be determined (glass or plastic may be suitable), 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

2 3 2

of the test specimen to the volume of water to which it is exposed, to be 40 (i.e. 40 m per 1m or 0,4 cm

3 2

per 1cm ). The volume of water required is therefore 25 l per m of exposed surface area of the test

3 2

specimen (this is equivalent to 2,5 cm per cm ). The container is covered to avoid any evaporation.

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.

3.5.2 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 wood. 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.
3.5.3 Vessel for receiving water

Laboratory glass flask or plastic jars, inert to water, treated wood and any substance that is to be

determined.
NOTE EN ISO 5667-3 gives the good practices to preserve water samples.
The brown glass flask or plastic jars shall be protected from heat and sunlight.
3.5.4 Preservative treatment

Equipment suitable for carrying out vacuum, vacuum-pressure, immersion or surface treatment of

specimens.
3.5.5 Balance
A balance capable of weighing to the nearest 0,1 g.
3.5.6 Safety equipme
