This test method is useful in determining the relative efficacy between various treatments and naturally occurring wood-destroying agents. It is an initial means of estimating the tolerance limits of the biologically destructive agents or the threshold values of the chemical preservative, or both. This test method is not intended to provide quantifiable reproducible values. It is a qualitative method designed to provide a reproducible means of establishing relative efficacy between experimental contract levels.1.1 This test method covers the relative effectiveness of wood preservatives in small wood specimens exposed to a natural marine environment. It is not within the scope of this test method to determine the retention or duration of protection for commercial size piles and timbers.1.2 The requirements for preparing the material for testing and the test procedures appear in the following order:SectionSummary of Test MethodTest Specimens Pretreatment Handling Treatment Procedure Post-Treatment Handling Assembly of Test Specimens Exposure Inspection Evaluation of Results Reports 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This Technical Specification 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 may also be used to test other treated wood species and naturally durable timbers. It may 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 Although the test is used to assess decay, it is possible to use the method to additionally assess stain or each separately when relevant.

This Technical Report specifies a method of test for the determination of the preventive action of a wood preservative against basidiomycetes fungi when the preservative is applied as a surface treatment to wood. This method is applicable to formulations of preservatives in a ready to use form as : water-insoluble chemicals which are being studied as active fungicides ; or organic formulations, as supplied or as prepared in the laboratory by dilution of concentrates ; or organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of concentrates ; or water-soluble materials, for example salts. NOTE This method can be used in conjunction with an appropriate ageing procedure, for example EN 73.

This European Standard gives guidance on the general procedures to be followed in the sampling and preparation for analysis of wood preservatives and preservative-treated timber. This European Standard is applicable to the provision of appropriate samples for analysis which can be used to check the content of active and other ingredients in preservative formulations, and the content of active and other ingredients of wood preservatives in treated timber, either before, during or after the service life of the timber. NOTE 1 Methods of sampling creosote and creosote-treated timber are described in EN 1014-1, 1014-2 and EN 12490. These are to be used in preference to the recommendations in this European Standard. NOTE 2 No attempt has been made in this document to lay down detailed procedures to be adopted for control purposes at manufacturing plants where large volumes of preservatives are to be sampled. Nor does it attempt to establish procedures for checking the compliance of batches of treated timber with specifications demanding a defined level of treatment (see 6.2).
