25、al corresponding to a temperature of 20 C and 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 whic
26、h is characterised by a moisture content in the material corresponding to a temperature of 20 C and a relative humidity of the surrounding air only exceeding 85 % for a few weeks per year NOTE Boards of this type are suitable for use only in hazard classes 1 and 2 of EN 335-3. DIN EN 622-4:2010-03 E
27、N 622-4:2009 (E) 5 3.3 external conditions conditions corresponding to service class 3 of EN 1995-1-1 which is characterised by climatic conditions leading to higher moisture contents than in service class 2 NOTE Boards of this type are suitable for use only in hazard classes 1, 2 and 3 of EN 335-3.
28、 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 stability to the works. NOTE Also referred to as “stru
29、cture“. 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 categories Load duration class Order of accumulated dur
30、ation 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 loadingaIn areas which have a heavy snow load for a prol
31、onged 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 requirements in the tables shall be met be 5 per
32、centile 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 values in the tables, and in the case of all other
33、 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 exception of swelling in thickness, the values given in
34、 the tables are characterised by a moisture content in the material corresponding to a temperature of 20 C and a relative humidity of 65 %. The values DIN EN 622-4:2010-03 EN 622-4:2009 (E) 6 given for swelling in thickness are characterised by a moisture content in the material corresponding to a t
35、emperature 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 external conditions (see Tables 3, 4 and 6) is reflected by the respective requirements for swelling in thickness after 2 h immersion in cold water
36、 (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 is derived from the addition of a hydrophobic substance such as a petrochemical or a natural substance. 4.2 Requirements for general purpose b
