Defines the requirements for flat-pressed or calendar-pressed unfaced particleboards as defined in EN 309.

This European Standard specifies the requirements for flat-pressed or calendar-pressed unfaced particleboards as defined in EN 309.

NOTE 1 This 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 2 Such 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 3 Particleboards 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.
