Particleboards - Specifications
This European Standard specifies the requirements for flat-pressed or calendar-pressed unfaced particleboards as defined in EN 309. The values listed in this standard relate to product properties, but they are not characteristic values to be used in design calculations. Additional information on supplementary properties for certain applications is also given. This standard does not apply to extruded particleboards and flaxboards, which are standardised in EN 14755 and EN 15197 respectively.
Spanplatten - Anforderungen
Diese Europäische Norm legt Anforderungen an kunstharzgebundene, unbeschichtete Spanplatten fest.
ANMERKUNG 1 Auf diese Norm wird in EN 13986 für Anwendungen im Bauwesen Bezug genommen.
Die in dieser Norm angegebenen Werte beziehen sich auf Produkteigenschaften; es sind keine
charakteristischen Werte, die für konstruktive Berechnungen verwendet werden können.
ANMERKUNG 2 Solche charakteristischen Werte (z. B. für konstruktive Berechnungen in ENV 1995-1-1) sind
entweder in EN 12369-1 angegeben oder werden durch Prüfung nach EN 789, EN 1058 und ENV 1156 ermittelt.

Panneaux de particules - Exigences
La présente Norme européenne prescrit les exigences pour les panneaux de particules liées à la résine et non revêtus.
NOTE 1 La présente norme est référencée dans la norme EN 13986 pour les applications dans la construction.
Les valeurs données dans la présente norme concernent les caractéristiques du produit mais ne sont pas les valeurs caractéristiques à utiliser dans les calculs de conception.
NOTE 2 De telles valeurs caractéristiques (par exemple pour des calculs de conception selon ENV 1995 1 1) sont soit données dans la norme EN 12369-1 soit obtenues à partir d’essais selon les normes EN 789, EN 1058 et ENV 1156.

EN 312:2010 (E) 4 1 Scope 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. 2 Normative references The following referenced documents are indispensable for the application of this document.

3.2 humid conditions conditions corresponding to service class 2 of EN 1995-1-1:2004 which 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 3.3 general purpose all non-load bearing applications, e.g. furniture and fitments 3.4 load-bearing
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 "structural use". 4 Classifications Seven types of boards are classified and are distinguished as follows: SIST EN 312:2011
EN 312:2010 (E) 6 P1 General purpose boards for use in dry conditions; P2 Boards for interior fitments (including furniture) for use in dry conditions; P3 Non load-bearing boards for use in humid conditions; P4 Load-bearing boards for use in dry conditions; P5 Load-bearing boards for use in humid conditions; P6 Heavy duty load-bearing boards for use in dry conditions; P7 Heavy duty load-bearing boards for use in humid conditions. 5 General requirements for all board types Particleboards shall comply with the general requirements as listed in Table 1 when dispatched from the production factory. For certain uses of particleboards (see performance standard EN 12871), special tolerances are required for the dimensional properties listed under No. 1. In the case of dispatch in cut sizes, or of further machined boards (tongued and grooved, and similar), special tolerances for properties No. 1, 2 and 3 may be agreed upon. SIST EN 312:2011
