Wood-based panels - Determination of characteristic 5-percentile values and characteristic mean values

On the basis of test results from wood-based panel products for structural purposes, this European Standard specifies a method for the determination of:
- characteristic 5-percentile values of mechanical properties under the assumption of a log-normal distribution of the test data according to EN 14358; and
- characteristic mean values (50-percentile values) of physical properties under the assumption of a normal distribution of the test data.
Test data should be determined from tests using the test methods outlined in EN 789.

Holzwerkstoffe - Bestimmung der charakteristischen 5-%-Quantilwerte und der charakteristischen Mittelwerte

Diese Europäische Norm legt ein Berechnungsverfahren auf der Grundlage von Prüfergebnissen von Holz-werkstoffen für tragende Zwecke fest zur Bestimmung von:
-   charakteristischen 5-%-Quantilwerten von mechanischen Eigenschaften unter Annahme einer log-normalen Verteilung der Prüfwerte nach EN 14358; und von
-   charakteristischen Mittelwerten (50-%-Quantilwerte) von physikalischen Eigenschaften unter Annahme einer Normalverteilung der Prüfwerte.
Die Prüfwerte sollten nach den in EN 789 angegebenen Prüfverfahren bestimmt werden.

Panneaux à base de bois - Détermination des valeurs caractéristiques correspondant au fractile à 5 % d'exclusion et des valeurs caractéristiques moyennes

Sur la base des résultats des essais des panneaux à base bois à but structurel, la présente Norme européenne spécifie une méthode pour la détermination :
-   des valeurs caractéristiques des propriétés mécaniques correspondant au fractile à 5 % d’exclusion, en supposant une distribution log-normale des données d’essai conformément à l’EN 14358 ; et
-   des valeurs caractéristiques moyennes des propriétés physiques (valeurs à 50 % d’exclusion) en supposant une distribution normale des données d’essai.
Il convient de déterminer les résultats d’essai à partir des essais utilisant les méthodes décrites dans l’EN 789

Lesne plošče - Ugotavljanje karakterističnih 5-percentilnih vrednosti in karakterističnih srednjih vrednosti

Na osnovi rezultatov preskusov lesnih plošč za konstrukcijske namene ta evropski standard opredeljuje metodo za določanje: značilnih 5-percentilnih vrednosti mehanskih lastnosti pod predpostavko log-normalne distribucije testnih podatkov v skladu z EN 14358; in značilnih srednjih vrednosti (50-percentilnih vrednosti) fizičnih lastnosti pod predpostavko normalne distribucije testnih podatkov. Testne podatke je potrebno določiti s pomočjo testov, z uporabo testnih metod, navedenih v EN 789.
