DIN EN 636:2015-05 EN 636:2012+A1:2015 (E) 5 1 Scope !This European Standard specifies the requirements for plywood, as defined in EN 313-2, for both general purpose use (non-structural application) and structural application
24、in dry, humid or exterior conditions. It also gives a classification system based on the bending properties. NOTE 1 This European Standard is referenced in EN 13986 for construction applications. This standard can be appropriately applied for all plywood, including overlaid and coated plywood, but i
25、t does not cover materials or processes used for overlaying or coating. Neither does it cover any materials or processes applied in relation to enhancement of biological durability. NOTE 2 For additional guidance on biological durability and the potential need for preservative treatment, according t
26、o application and serviceability, reference can be made to CEN/TS 1099. The values listed under Clause 4 relate only to product properties; they are not characteristic values and are not to be used in design calculations. NOTE 3 Characteristic values (i.e. for use in design calculation according to
27、EN 199511) are given either in EN 123692 which is based on the classification system given in this standard or by the manufacturer based on testing according to EN 789, EN 1058 and ENV 1156. Additional information on supplementary properties for certain applications is also given.“ 2 Normative refer

40、 dry conditions plywood to be used in conditions 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 65 % for a few weeks per year Note 1 to entry: These conditions correspond with Service Class 1 ac
41、cording to EN 19951-1. Note 2 to entry: Boards of this type are suitable for use in Use Class 1 of EN 3353. 3.2 plywood for use in humid conditions plywood to be used in conditions characterised by a moisture content in the material corresponding to a temperature of 20 C and relative humidity of the
42、 surrounding air only exceeding 85 % for a few weeks per year Note 1 to entry: These conditions correspond with Service Class 2 according to EN 19951-1. Note 2 to entry: Boards of this type are suitable for use in Use Class 1 and 2 of EN 3353. Note 3 to entry: This type of plywood is appropriate for
43、 protected external applications (e.g. behind cladding or under roof coverings), but is also capable of resisting weather exposure for short periods (e.g. when exposed during the construction). It is also suitable for interior situations where the service moisture condition is raised above humidity
44、of dry conditions. 3.3 plywood for use in exterior conditions plywood to be used in climatic conditions leading to higher moisture contents than in service class 2 Note 1 to entry: These conditions correspond with Service Class 3 according to EN 19951-1. Note 2 to entry: Boards of this type are suit
45、able for use in Use Class 1, 2 and 3 of EN 3353. Note 3 to entry: This type of plywood is capable of withstanding exposure to weathering conditions and liquid water, or water vapour in a damp but ventilated location, under consideration of 9.2. 4 Symbols and subscripts E modulus of elasticity (defin

The classification system may be used as an alternativ
48、e to the full-scale testing as required by EN 789, for the derivation of characteristic values for plywood, by cross-referencing with EN 12369-2 for the characteristic values of each class listed in Tables 1 and 2. The lower limit values given in Tables 1 and 2 for bending strength and modulus of elasticity in bending correspond to 5 percentile values based on the mean values, determined according to EN 310 and EN 326-2 for individual boards and calculated in accordance with EN 326-1. These values shall not be used for structural desi
