This part of EN 351 gives guidance on the general procedures to be used in obtaining samples of preservative-treated wood for the determination of penetration and retention of wood preservative. It also gives guidance on how to measure the penetration and retention of a wood preservative in the treated wood.
This part of EN 351 is applicable to the production of preservative-treated solid wood, including glued laminated timber, suitable for use in those service conditions defined by the use classes in EN 335.
This part of EN 351 is not applicable to preservative-treated wood in service. However, the sampling guidance provided within this part of EN 351 may be applied for the subsequent examination of treated wood in service.
Annex A (informative) provide a selection of number of sampling units.
Annex B (informative) provides examples of retention measurements.

This part of EN 351 establishes a classification of preservative-treated wood in terms of preservative penetration and gives guidance on a classification of retention. These shall be used as a basis for specifying preservative treatments for particular products.
This part of EN 351 provides terminology to be used by the specifier when preparing a preservative treatment specification or product standard. It is not a treatment specification in itself.
This part of EN 351 is applicable to the production of preservative-treated solid wood, including glued laminated timber, suitable for use in those service conditions defined by the use classes in EN 335. It does not apply to any subsequent examination of treated wood in service.
This part of EN 351 is applicable to the protection of wood against attack by wood-destroying and wood-disfiguring fungi, insects and marine organisms.
NOTE Protection against wood-disfiguring fungi is an optional property verified by testing in accordance with EN 599-1.
This part of EN 351 does not consider other properties of treated wood, for example odour, compatibility with other materials, such as corrosivity of fasteners. Nor does it consider any properties from the health, safety and environmental point of view.
This part of EN 351 does not apply to wood to be treated with formulations which are applied to timber in service to eliminate or control an existing fungal or insect infestation, or the prevention of attack by sapstain fungi, or insects in green timber.
Annex A (informatives) provides a decision process for defining preservative treatment requirements.
Annex B (informative) gives an example of the marking system.

This document describes a method of test for wood preservatives that are intended for use in wood to be exposed to the weather out of contact with the ground without the additional protection of a surface coating.
The method is applicable to the testing of commercial or experimental preservatives applied by techniques appropriate to commercial practice. The method is applicable to chemical products used individually or in combination to prevent the development of decay and/or - optional - the development of disfiguring organisms in wood and, where suitable, in wood-based products.
NOTE 1 The method can also be used to test other treated wood species and naturally durable timbers. It can be adapted for testing the field performance of other wood based systems and treatments designed to enhance durability, for example treated or untreated wood based composites, timber treated with non-biocidal systems, chemically modified or heat treated timber.
NOTE 2 Altough the test is used to assess decay, it is possible to use the method to additionally assess stain or each separately when relevant.

This document specifies a laboratory method for the determination of the treatability of wood in order to determine the likely reaction of different wood species to impregnation with wood preservatives. It is also applicable to investigate variation between samples of the same species but of different origin.

This document is intended to facilitate the interpretation and use of the European Standards where the testing and specification of wood preservative products are described. It aims to assist users (manufacturers, specifiers, authorities, etc.) to correlate the choice of selected test methods, wood substrates and biological agents with the efficacy requirements of wood preservatives based on their claimed target organisms and end use. This document is a source of supplementary information to the relevant standards and cannot be used as a standalone document.

This document provides guidance on how to apply curative acting wood preservatives by surface application, by filling pre-drilled holes, and by pressure impregnation through pre-drilled holes. It lists methods in a standardized form followed by additional detailed interpretive information.
This document also includes necessary preparations of structural timber prior to this kind of treatment. It gives guidance on how to calculate necessary retentions for filling pre-drilled holes or for pressure impregnation from test results obtained from surface applications (e.g. EN 1390).

This document specifies a method of test for determining the natural durability of a timber against wood-destroying basidiomycetes cultured on a malt extract agar medium. The method is applicable to all timber species.
Furthermore this method can be used to test modified wood. The test method described in this document can be applied to specific wood species, commercial supplies of sawn timber, wood-based materials, wood treated with preservatives and modified wood, both thermally and chemically modified wood.
However, this document is not intended to determine the effectiveness of wood preservatives used to prevent decay.
NOTE 1 Determining the efficacy of wood preservatives used to prevent decay is the scope of EN 113-1. However, in addition to this and with some amendments, it might also be possible in some cases to test treated wood using the method described here.
NOTE 2 This method can be used in conjunction with an ageing procedure, for example EN 73 or EN 84.
Annex A (informative) contains a guidance on sampling.
Annex B (normative) contains some methods of sterilization.
Annex C (informative) contains information on the culture vessels.
Annex D (informative) contains an example of a test report.
Annex E (informative) contains information on the test fungi.
Annex F (informative) contains the assessment of the results.

This document specifies a method for the leaching of test specimens of wood which are used in the testing of the biological efficacy of wood preservatives.
This standard is applicable to:
a) the pre-conditioning of test specimens prior to their being subjected to a biological test ; or
b) assessment of loss of effectiveness by comparing the performance in a biological test of treated test specimens subjected to this procedure with others that have not undergone any leaching procedure.
NOTE The method may also be used for pre-conditioning of wood-based panel products which may or may not have received preservative treatment.
