The values listed in this European Standard relate to product properties but they are not characteristic values to be used in design
20、 calculations. NOTE Panels which are intended for use exclusively as thermal insulating products are covered by EN 13171. 2 Normative references The following referenced documents are indispensable for the application of this document.

25、 a relative humidity of the surrounding air only exceeding 65 % for a few weeks per year NOTE Boards of this type are suitable for use only in hazard class 1 of EN 335-3. 3.2 humid conditions conditions corresponding to service class 2 of EN 1995-1-1 which is characterised by a moisture content in t

28、se only in hazard classes 1, 2 and 3 of EN 335-3. 3.4 general purpose use all non-load-bearing applications NOTE e. g. fitments and underlays. 3.5 loading-bearing use use in a load-bearing construction, i.e. an organized assembly of connected parts designed to provide mechanical resistance and stabi
29、lity to the works. NOTE Also referred to as “structure“. 3.6 load duration class class characterised by the effect of a constant load acting for a certain period of time in the life of the structure NOTE The load duration classes are defined in EN 1995-1-1 (see Table 1). Table 1 Load duration catego
30、ries Load duration class Order of accumulated duration of characteristic load Examples of loading Permanent more than 10 years self weight Long term 6 months to 10 years storage Medium term 1 week to 6 months imposed load Short term less than one week snow a , wind Instantaneous - accidental loading
31、aIn areas which have a heavy snow load for a prolonged period of time, part of the load should be regarded as medium-term. 4 Requirements 4.1 General Softboards shall comply with the general requirements of EN 622-1 together with the relevant requirements set out in 4.2 and 4.3 of this standard. The
32、 requirements in the tables shall be met be 5 percentile values (95 percentile values in the case of swelling in thickness), based on the mean test values for individual panels and calculated in accordance with EN 326-1. In the case of swelling in thickness, they shall be equal to or less than the v
33、alues in the tables, and in the case of all other properties, they shall be equal to or greater than the values in the tables. The values in the tables for both bending strength and modulus of elasticity shall apply to test results obtained in any direction in the plane of the panel. With the except
34、ion of swelling in thickness, the values given in the tables are characterised by a moisture content in the material corresponding to a temperature of 20 C and a relative humidity of 65 %.

35、S EN 622-4:2009EN 622-4:2009 (E) 6 given for swelling in thickness are characterised by a moisture content in the material corresponding to a temperature of 20 C and a relative humidity of 65 % before the treatment (immersion in water). The moisture resistance of softboards for use in humid and exte
36、rnal conditions (see Tables 3, 4 and 6) is reflected by the respective requirements for swelling in thickness after 2 h immersion in cold water (according to EN 317). This property as well as the improvement of mechanical resistance of boards use in instantaneous or short-term load-bearing situation
37、 is derived from the addition of a hydrophobic substance such as a petrochemical or a natural substance. 4.2 Requirements for general purpose boards 4.2.1 Requirements for boards for use in dry conditions Table 2 specifies the requirements for general purpose boards for use in dry conditions.
