Extruded particleboards - Specifications

This European Standard specifies the requirements for non load-bearing extruded particleboards for use in dry conditions.
NOTE   Dry conditions are defined in terms of service class 1 of EN 1995-1-1 which is characterized 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. Boards of this type are only suitable in biological hazard class 1 of EN 335-3.

Spanplatten nach dem Strangpressverfahren (Strangpressplatten) - Anforderungen

Diese Europäische Norm legt die Anforderungen an nicht tragende Spanplatten nach dem Strang-pressverfahren
(Strangpressplatten) zur Verwendung im Trockenbereich fest.
ANMERKUNG Der Trockenbereich ist definiert durch die Nutzungsklasse 1 nach EN 1995-1-1, gekennzeichnet durch
einen Feuchtegehalt des Materials, der einer Temperatur von 20 °C und einer relativen Luftfeuchte der umgebenden Luft
entspricht, die nur für einige Wochen pro Jahr einen Wert von 65 % übersteigt. Platten dieses Typs eignen sich für die
Verwendung in der Gefährdungsklasse 1 nach EN 335-3.

Panneaux de particules extrudés - Exigences

La présente norme prescrit les exigences des panneaux de particules extrudés non travaillants utilisés en milieu
sec.
NOTE Le milieu sec est défini par la classe de service 1 de l?ENV 1995-1-1 qui est caractérisé par une humidité dans le
matériau qui correspond a une température de 20 °C et une humidité relative de l?air ambiant dépassant 65 % seulement
quelques semaines par an. Les panneaux de ce type sont aptes a etre utilisés dans la classe d?emploi biologique 1 selon
l?EN 335-3.
