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.
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.
