This European Standard specifies the requirements for flat-pressed or calendar-pressed unfaced particleboards as defined in EN 309.NOTE 1This standard is called up in EN 13986 for construction applications. Products specified in this standard are referred to in EN 13986 as resin-bonded particleboards.The values listed in this standard relate to product properties, but they are not characteristic values to be used in design calculations.NOTE 2Such characteristic values (e.g. for use in design calculation in EN 1995-1-1) are given either in EN 12369-1 or derived by testing according to EN 789, EN 1058 and ENV 1156.Additional information on supplementary properties for certain applications is also given.NOTE 3Particleboards in accordance with this standard may be referred to as P1 to P7-boards.Boards of type P4 to P7 are intended for use in design and construction of load-bearing or stiffening building elements, e.g. walls, flooring, roofing and I-beams (see EN 1995-1-1 and/or performance standards).This standard does not apply to extruded particleboards and flaxboards, which are standardised in EN 14755 and EN 15197 respectively.
