29、s been prepared by Technical Committee CEN/TC 38 “Durability of wood and wood-based products”, the secretariat of which is held by AFNOR. This document is currently submitted to the CEN Enquiry. This document will supersede EN 599-1:1996. Significant technical differences between this edition and EN
30、 599-1:1996 are as follows: The scope now emphasises that this standard is not a performance standard but a standard for characterising the efficacy of wood preservatives, based on data derived from the biological tests that it specifies supplemented by, in certain cases data from field tests. The s
31、tandard provides a basis for establishing preservative retentions for timber when specified in accordance with EN 351-1 taking into account necessary local considerations. It points out that at present not all natural ageing factors which may effect the stability of active ingredients for wood prese
32、rvatives can be assessed by standardized methods but have nevertheless to be taken into account in the development of preservative products capable of being effective in service. It also allows for preservatives that have been used successfully and legally before the standard was developed and provi
33、des for confirmation of their efficacy in accordance with the general principles of the standard (so called “grandfather-clause”). This standard now provides for the use of data from ENV 839 , in specific cases, as a method for the assessment of preservatives designed for superficial applications. T
34、he amendment of ENV 807 has been taken into consideration. In Annex A “Guidance on re-testing after making variations in product formulation”, requirements have been clarified by the provision of diagrams. Production control has been withdrawn from paragraph 9 and transferred to a new informative an
35、nex (now Annex B). A new normative annex on the validity of test results from former standards after their revision has been added (now Annex H). All remaining annexes have been renumbered. EN 599 consists of two parts. Part 2 (EN 599-2 Durability of wood and wood-based products Performance of preve
36、ntive wood preservatives as determined by biological tests Part 2: Classification and labelling) will be revised later once the exact requirements of the Biocidal Products Directive have been finalised.

37、T+00:00 2007, Uncontrolled Copy, (c) BSI prEN 599-1:2007 (E) 4 Introduction This Part of EN 599 is one of a series and should be used in conjunction with EN 599-2, with EN 335-1 and EN 335-2 which describe the service conditions for treated wood in terms of use classes, and with EN 351-1 which descr
38、ibes a classification system for preservative treated wood in terms of preservative penetration and gives guidance on classes for retentions. The need for wood preservatives depends in part on the natural durability of the wood and therefore this Part of EN 599 should be used also in conjunction wit
39、h EN 350-1, EN 350-2 and EN 460. Licensed Copy: London South Bank University, London South Bank University, Fri Oct 05 02:48:46 GMT+00:00 2007, Uncontrolled Copy, (c) BSI prEN 599-1:2007 (E) 5 1 Scope This part of EN 599 specifies for each of the five use classes defined in EN 335-1, the biological
40、tests required for evaluating the efficacy of wood preservatives for the preventive treatment of solid timber, together with the minimum ageing tests required for the respective use class. As provided for in EN 351-1, it provides the method for calculating the critical value of a preservative. The c
41、ritical value is the value that shall be used to calculate the recommended retention of the preservative appropriate for specific service conditions. The critical value is not necessarily the recommended retention or the minimum retention level for the preservative. The wide range of hazards, exposu
42、re conditions and service life requirements across Europe make it necessary to allow for local considerations in the calculation of the required preservative retention; EN 351-1 provides for the critical value to be adjusted to take account of these factors. This Part of EN 599 is applicable to all
43、wood preservative products supplied for application in liquid form for the preventive treatment of timbers (structural and non-structural) against wood-attacking fungi, wood-attacking insects and marine borers as described in EN 335-1. However it is only applicable to products for preventive treatme
44、nts against fungi causing disfigurement (blue stain) of wood in service if this forms part of the overall preventive efficacy of the product. This part of EN 599 does not necessarily take into account all of the factors which may affect the stability of active ingredients in preservative treated woo
45、d. These factors include ultra-violet light and microbiological agencies capable of degrading components of the preservative. Such factors are an integral part of exposure in field trials but are subject to natural variation and their impact is not directly assessed in the field trial methods includ
46、ed in this standard. Methods are in development to assess the impact of these factors but are not finalised and cannot be included in this revision of this part of EN 599. Because such factors could, in service, significantly affect the active ingredients suitability for its intended purpose, the ma
47、nufacturer/producer is expected to ensure and be able to provide evidence that its stability, at the recommended retention of the preservative product, has been adequately assessed. This Part of EN 599 is not applicable to wood preservative products supplied for application as pastes, solids or in c
48、apsule or gaseous form because they cannot be tested without modification of the biological tests demanded in this standard. It does not apply either to wood preservative products for remedial (curative) treatments, to those applied to prevent fungi causing sap stain on green (unseasoned) timber or
49、to those applied solely to prevent fungi causing disfigurement (blue stain) of wood in service. NOTE 1 The nature of the laboratory and field tests required in this Part of EN 599 to demonstrate efficacy of a wood preservative are such that the time required generating the data is many months or years, depending upon the properties of the wood preservative and the use class in which the treated wood is to be exposed. For preservative products which have already been plac
