15、pplications for use in humid conditions. NOTE 1 Dry conditions are defined in terms of service class 1 of EN 1995-1-1 which is characterized by the moisture content in the material corresponding to a temperature of 20 C and a relative humidity of the surrounding air only exceeding 65 % for a few wee
16、ks per year. Boards of this type are only suitable for use in biological hazard class 1 of EN 335-3. Humid conditions are defined in terms of service class 2 of EN 1995-1-1, which is characterised by a moisture content in the material corresponding to a temperature of 20 C and a relative humidity of
17、 the surrounding air only exceeding 85 % for a few weeks per year. NOTE 2 This standard will be referred to in EN 13986, as far as construction applications are concerned. NOTE 3 Boards in accordance with this standard may be referred to as FB1, FB2, FB3 or FB4 boards. The values listed in this stan
18、dard relate to product properties but they are not characteristic values to be used for design calculations. 2 Normative references The following referenced documents are indispensable for the application of this document.

25、s For the purposes of this document, the following term and definition applies. 3.1 flaxboard particleboard as defined in EN 309 manufactured under pressure and heat from flax shives, with the addition of an adhesive which contains at least 70 % flax and which can also contain other raw materials su
26、ch as particles of wood (wood flakes, chips, shavings, saw dust and similar materials) 4 Classification Type FB1 General purpose flaxboard for use in dry conditions (usually for filling purposes). Type FB2 Non-load bearing flaxboard for use in dry conditions (usually for further processing, such as
27、veneering). Type FB3 Flaxboard for interior fitment (including furniture) for use in dry conditions. Type FB4 Non-load bearing flaxboard for use in humid conditions.
