25、ed by Technical Committee CEN/TC 38 “Durability of wood and wood-based products”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2017, and conf

26、licting national standards shall be withdrawn at the latest by February 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

27、s EN 350-1:1994 and EN 350-2:1994. Wood durability is an important factor that influences the service life of a wood product. This standard provides input to service life prediction of wood and wood-based products. Its intended to give guidance on using wood products appropriate for different end-us

28、es avoiding excessive requirements. It also ranks durability against wood-decay organisms of various wood species thereby allowing species of appropriate durability to be selected for a particular use. It will however be emphasized that the biological durability rating of wood species given in Annex

29、 B cannot be regarded as any guarantee of performance in service. There are many other factors influencing service life of a wood product, such as the principles of good design, use conditions, climate, maintenance which should be taken into consideration. According to the CEN-CENELEC Internal Regul

30、ations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, It

31、aly, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. DIN EN 350:2016-12 EN 350:2016 (E) 5 1 Scope This European Standard gives guidance on methods for determining and classifying the

32、durability of wood and wood-based materials against biological wood-destroying agents. The methods can be applied either to individual wood species, batches of wood and processed wood-based materials, including heat-treated, preservative-treated wood and modified wood. However, this standard is not

33、intended to replace testing of the efficacy of biocides. The wood-destroying agents considered in this standard are: wood-decay fungi (basidiomycete and soft-rot fungi); beetles capable of attacking dry wood; termites; marine organisms capable of attacking wood in service. Data on the biological dur

34、ability of selected wood species considered of economic importance in European countries are presented in Annex B (informative), which also provides information relating to their geographical origin, density, sapwood width and treatability. NOTE Treatability, durability to disfiguring fungi, permeab

35、ility to water and performance in use of wood and wood-based materials are also important issues. However, because standardized methods aiming to assess and classify these factors do not exist and/or have not been extensively experienced yet, preliminary guidance is given in Annex C (informative) fo

36、r the classification of wood treatability with aqueous wood preservatives, Annex D (informative) for the classification of the permeability to water, Annex E (informative) for the durability to disfiguring fungi, and Annex F (informative) for the classification of performance. 2 Normative references

45、g. European oak which comprises both Quercus robur and Q. petraea. 3.2 pilot name for a wood species result of a consensual choice due to practical considerations retaining the usual name under which the wood is the most widely commercialised, adopted either by the main exporting country or by the m

46、ain importing country Note 1 to entry: Pilot names are established since 1954 in the nomenclature of the ATIBT. 3.3 set clearly identifiable collection of units of wood or wood-based products, originating from a commercial supply of a defined origin (single or not) and likely comprising only some of

48、ved from trees and include amongst others heat-treated wood and any other material modified by chemical, physico-chemical or physical process, glue-laminated wood, wood-based panels, wood polymer composites and treated with wood preservatives. This standard is not meant to test all ligno-cellulosic

49、materials (e.g. bamboo, reed, straw, flax) as such and would require methodological adaptions to do so.
