20、Introduction This part of EN 351 allows a specifier or user to choose a preservative treatment for a solid wood product taking into a account its intended service or the needs of different regional or traditional practices throughout Europe and the use class conditions to which the solid wood produc

21、ts will be exposed (see EN 335-1). In addition, it provides the basis on which treatments for timber in European product standards are to be defined. No attempt has been made to quantify the working life that could be expected from a particular preservative treatment as this will depend on the geogr

22、aphical location and the associated climate of the service environment. The performance of treated wood cannot be assessed directly, for example by field tests or bioassay, as no agreed documents specifically for this purpose exist. As a consequence, the penetration and retention of a preservative i

23、n treated wood are used to define quality of treatment. The penetration and retention values are measured by analysing the active ingredient(s) in the treated wood. Preservative treatment for certain wood species used in the different use classes might be unnecessary owing to their natural durabilit

24、y (see EN 350-2 and EN 460). If appropriate treatment is necessary, the specification for appropriate preservatives is defined in EN 599-1. Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 16/04/2008 08:24, Uncontrolled Copy, (c) BSIEN 351-1:2007 (E) 5 1 Scope This part of EN 351 establishes c

25、lassification for preservative-treated wood in terms of preservative penetration and gives guidance on a classification of retention. These should 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 w

26、hen 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 t

27、he use classes in EN 335-1. 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. This part of EN 351 does not consider other

28、properties of treated wood, for example odour, corrosiveness and compatibility with other materials, 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 treated with formulations that are applied to timber in service

29、 to eliminate or control an existing fungal or insect infestation, or to prevent attack by sapstain fungi, or insects in green timber. 2 Normative references The following referenced documents are indispensable for the application of this document.
