(Main)Hardware for furniture - Strength and durability of extension elements and their components
Hardware for furniture - Strength and durability of extension elements and their components
This European Standard specifies test methods and requirements for the strength and durability of all types of extension elements and their components for all fields of application, except table extensions.
The tests consist of the application of loads, forces and velocities simulating normal functional use, as well as misuse, that might reasonably be expected to occur.
With the exception of the corrosion test in 6.4, the tests are designed to evaluate properties without regard to materials, design/construction or manufacturing processes.
The strength and durability tests only relate to the extension elements and the parts used for the attachment, e.g. screws.
The strength and durability tests are carried out in a test frame with specified properties. The test results can only be used as a guide to the performance of a piece of furniture.
The test results are only valid for the extension element tested. These results may be used to represent the performance of production models provided that the tested model is representative of the production model.
Ageing and influences of heat and humidity are not included.
Möbelbeschläge - Festigkeit und Dauerhaltbarkeit von Auszügen und deren Komponenten
Dieses Dokument legt Prüfverfahren und Anforderungen für die Festigkeit und Dauerhaltbarkeit aller Arten von Auszügen und deren Komponenten für alle Anwendungsbereiche fest, mit Ausnahme von Tischauszügen.
Bei den Prüfungen werden Lasten, Kräfte und Geschwindigkeiten aufgebracht, die einer normalen funktions¬bedingten Benutzung sowie auch einer vorhersehbaren Fehlanwendung entsprechen.
Mit Ausnahme der Korrosionsprüfung nach 6.4 sind die Prüfungen auf die Bewertung von Eigenschaften ausgerichtet, ohne Berücksichtigung von Werkstoffen, Gestaltung/Konstruktion oder Herstellverfahren.
Die Prüfungen der Festigkeit und Dauerhaltbarkeit beziehen sich nur auf die Auszüge und die Teile für die Befestigung, z. B. Schrauben.
Die Prüfungen der Festigkeit und Dauerhaltbarkeit werden in einem Prüfrahmen mit festgelegten Eigenschaften durchgeführt. Die Prüfergebnisse können nur als Hinweis für die Gebrauchstauglichkeit eines Möbelstückes herangezogen werden.
Die Prüfergebnisse sind nur für den geprüften Auszug gültig. Diese Ergebnisse dürfen zur Darstellung der Gebrauchstauglichkeit von Produktionsserien herangezogen werden, vorausgesetzt, das geprüfte Modell ist für die Serie repräsentativ.
Alterung und die Einwirkungen von Wärme und Feuchte sind nicht enthalten.
Quincaillerie d'ameublement - Résistance mécanique et endurance des éléments extractibles et de leurs composants
Le présent document spécifie des méthodes d’essai et des exigences relatives à la résistance mécanique et à l’endurance de tous les types d’éléments extractibles et de leurs composants prévus pour tous les champs d’application, à l’exception des rallonges de table.
Les essais consistent à appliquer des charges, forces et vitesses simulant un usage fonctionnel normal et un mauvais usage auquel on peut raisonnablement s’attendre.
À l’exception de l’essai de corrosion décrit en 6.4, les essais sont conçus pour évaluer les propriétés quels que soient les matériaux, la conception/construction et les procédés de fabrication.
Les essais de résistance mécanique et d’endurance concernent uniquement les éléments extractibles et les parties utilisées pour leur fixation, par exemple des vis.
Les essais de résistance mécanique et d’endurance sont effectués dans une structure d’essai ayant des propriétés spécifiées. Les résultats d’essai peuvent uniquement servir de guide en matière de performances d’un meuble.
Les résultats d’essai ne sont valables que pour les éléments extractibles soumis à essai. Ces résultats peuvent être utilisés pour indiquer les performances des modèles fabriqués à condition que le modèle soumis à essai soit représentatif du modèle fabriqué.
Le vieillissement et les effets de la chaleur et de l’humidité ne sont pas traités.
