Introduction

This CEN Technical Specification specifies a field test method which gives a basis for assessing the

effectiveness of a wood preservative product for the protection of freshly felled timber against colonization by

sapstain, mould and other disfiguring micro-organisms. This field test method provides one criterion by which

the value of a product can be assessed. If little is known about the activity of a product against sapstain and

mould fungi, it is advisable to carry out a preliminary laboratory assessment using a suitable method.

To ensure that colonization of the test specimens will occur, the test should be carried out at sites where

sapstain and mould growth occur on untreated susceptible timber species and should be carried out to

coincide with the periods of higher fungal activity.

NOTE Periods of highest fungal activity are usually in the spring and autumn. If tests have not been conducted at a

location previously, local experience should be sought to determine the most appropriate time of year.

The procedures described in this CEN Technical Specification are intended to be carried out by suitably

trained and/or supervised specialists. Appropriate safety precautions should be observed throughout the use

of the CEN Technical Specification.

1 Scope

This CEN Technical Specification specifies a field test method for determining the effectiveness of a product in

the prevention of the colonization of freshly felled wood by sapstain fungi and mould fungi.

2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
representative sample

sample having its physical or chemical characteristics identical to the volumetric average characteristics of the

total volume being sampled
2.2
supplier

sponsor of the test (person or company providing the sample of wood preservatives to be tested)

3 Principle

Treatment of several series of test specimens of a susceptible wood species with solutions in which the

concentrations of the test product are ranged in a given progression. Treatment of two series of similar test

specimens with defined concentrations of a reference formulation. Exposure of these test specimens to

colonization by the natural microflora. Comparison of the effectiveness of the test product with that of the

reference formulation and the untreated control test specimens.
4 Test material and apparatus
4.1 Products and reagents
4.1.1 Diluents

For water-soluble or water-diluable preservatives use water of drinkable quality.

4.1.2 Reference formulation
Copper-8-quinolinolate.
NOTE 1 Details on this wood preservative are given in Annex A.

NOTE 2 If experience with another reference formulation is available in field tests in comparison with copper-8-

quinolinolate, then an equivalent reference formulation can be used.

SIST-TS CEN/TS 15082:2008
CEN/TS 15082:2005 (E)
4.2 Apparatus

4.2.1 Dipping tank, suitable for dipping the size of test specimen used (see 6.3) and the volume of solution

(see 7.1.1).

4.2.2 Supports, for the test specimens during exposure. The supports shall be made of the same species of

timber as the test specimens or any inert material, that it is to say with no risk or interacting with the test

specimens or the reference and test preservative treatments. They shall provide support for the test

specimens between 100 mm and 200 mm above the level of the surrounding ground.

NOTE It is convenient to use pallets so that complete stacks can be moved mechanically.

4.2.3 Stickers, to separate the test specimens in the top half of each stack. The stickers shall be made of

the same species of timber as the test specimens and treated with the same concentration of preservative, or

any inert material, that is to say with no risk of interacting with the test specimens or the reference and test

preservative treatments. The stickers shall separate the test specimens by (20 ± 5) mm.

4.2.4 Securing bands, to secure the test specimens in the stack during storage.

4.2.5 Exposure site, an open area free from extremes of local environmental influences, especially

industrial pollution. The type of surface (e.g. grass, soil or concrete) shall be the same for all stacks in any test

and details shall be recorded in the test report. Any vegetation shall be maintained at a level below that of the

top of the supports on which the test specimens are stacked (see 4.2.2).

The prevailing meteorological conditions during the test exposure period shall be recorded and included in the

test report.

4.2.6 Ordinary laboratory equipment, including a balance capable of weighing to an accuracy of 1 g.

5 Sampling of the preservative

The sample of preservative shall be representative of the product to be tested. Samples shall be stored and

handled in accordance with any written recommendations from the supplier.

NOTE For the sampling of preservatives from bulk supplies, the procedure given in EN 212 should be used.

6 Test specimens
6.1 Species of wood

The species of wood to be used shall be susceptible to attack by sapstain and mould fungi.

The reference species should be a susceptible pine species, either Scots pine (Pinus sylvestris Linnaeus),

Corsican pine (Pinus nigra var. maritime) or maritime pine (Pinus pinaster).

NOTE Tests can be undertaken using other species (e.g. spruce, beech) corresponding to the above characteristics

and of particular importance for certain countries, but a reference pine species treated with the reference formulation

should also be included to validate the severity of the test. When the test has been conducted using other species (e.g.

spruce, beech) the results are only valid for that species.

6.2 Wood quality

The wood shall be free from cracks, stain, decay, insect damage and other defects but sound knots are

permitted. The wood shall not have been water-stored, floated, chemically treated or steamed. The wood shall

originate from trees felled in spring or autumn. The trees shall be conve
