Hardware for furniture - Test method for strength and overload tests of connectors for furniture constructed from panel material
This document specifies test methods for the strength and overload tests of connectors for furniture constructed from panel material and procedures for evaluating test results.
The document is specifically intended for assessing of cabinet connectors for carcases made of wood-based panel materials. The methods described can, however, be used to assess the relative performance of other types of connectors, e.g. some types of connectors for beds.
The strength and overload tests only apply to the connectors and their components, as well as the mounting to and in the cabinet carcase. It does not apply to additional functions that the connector may have e.g. covering of the connector.
The tests described are carried according to a test setup with specified properties and characteristics.
The test results are only valid for the connector tested. The results can be used to represent the performance of production models, provided the tested model is representative of the production model.
Aging and the influences of temperature and humidity are not included. The standard contains four informative annexes, providing additional methodologies for the detailed evaluation of the test results, and a procedure for comparing the tested connector with a reference connector.
Annex A (informative) – Reference connector – Glued dowel
Annex B (informative) – Ratio generation
Annex C (informative) – Stiffness calculation for further evaluation of the overload
Annex D (informative) – Evaluation by the characteristic value (5% percentile)

Die beschriebenen Verfahren können jedoch auch angewendet werden, um die entsprechende Leistungsfähigkeit anderer Korpuseckverbinderarten zu beurteilen, darunter einige Arten von Korpuseckverbindern für Betten.
Die Festigkeits und Schwellbelastungsprüfungen sind nur für die Korpuseckverbinder und ihre Einzelteile sowie die Befestigung an und in dem Korpus anwendbar. Sie gelten nicht für zusätzliche Funktionen, die der Korpuseckverbinder haben kann, z. B. die Abdeckung des Korpuseckverbinders.
Die in diesem Dokument beschriebenen Prüfungen werden mit einem Prüfaufbau mit festgelegten Eigenschaften und Merkmalen durchgeführt.
Die Prüfergebnisse gelten nur für den geprüften Korpuseckverbinder. Die Ergebnisse können verwendet werden, um die Leistungsfähigkeit von Serienmodellen anzugeben, sofern das geprüfte Modell repräsentativ für das Serienmodell ist.
Alterung und der Einfluss von Temperatur und Feuchtigkeit werden nicht berücksichtigt. Dieses Dokument enthält vier informative Anhänge, die zusätzliche Vorgehensweisen für eine eingehende Auswertung der Prüfergebnisse sowie ein Verfahren für den Vergleich des geprüften Korpuseckverbinders mit einer Referenzverbindung beschreiben.
- Anhang A (informativ) - Referenzverbindung - Geklebter Dübel;
- Anhang B (informativ) - Berechnung der Verhältniszahl;
- Anhang C (informativ) - Berechnung der Steifigkeit zur weiteren Beurteilung der Schwellbelastung;
- Anhang D (informativ) - Beurteilung nach dem charakteristischen Wert (5 % Quantil).

Le présent document spécifie les méthodes d’essai pour les essais de résistance mécanique et de charge seuil des ferrures d’assemblage de meubles constitués de panneaux à base de bois, ainsi que les procédures d’évaluation des résultats d’essai.
Ce document est spécialement destiné à évaluer les ferrures d’assemblage d’armoires à carcasse en panneaux à base de bois. Ces méthodes peuvent toutefois servir aussi à évaluer la performance relative d’autres types de ferrures d’assemblage ; par exemple certains types de ferrures d’assemblage pour lit.
Les essais de résistance mécanique et de charge seuil ne s’appliquent qu’aux ferrures d’assemblage et à leurs composants, ainsi qu’au montage à et dans la carcasse d’armoire. Ils ne portent pas sur des fonctions supplémentaires que les ferrures d’assemblage puissent avoir ; par exemple le recouvrement du moyen d’assemblage.
Les essais décrits dans le présent document sont réalisés selon une configuration aux propriétés et caractéristiques spécifiées.
Les résultats d’essai ne sont valables que pour la ferrure d’assemblage soumise à l’essai. Ces résultats peuvent être utilisés pour indiquer les performances des modèles fabriqués à condition que le modèle soumis à l’essai soit représentatif du modèle fabriqué.
Le vieillissement et l’influence de la température et de l’humidité ne sont pas pris en compte. Ce document contient quatre annexes informatives qui fournissent des méthodologies supplémentaires pour l’évaluation détaillée des résultats d’essai, ainsi qu’une procédure pour comparer la ferrure d’assemblage soumise à l’essai à un moyen d’assemblage de référence :
- Annexe A (informative) - Moyen d’assemblage de référence - Cheville collée ;
- Annexe B (informative) - Génération du ratio ;
- Annexe C (informative) - Calcul de rigidité pour compléter l’évaluation de la charge seuil ;
- Annexe D (informative) - Évaluation de la valeur caractéristique (5ème centile).

Connectors which include structural hardware parts made of hygroscopic plastic materials, e.g.
polyamide in load-bearing function shall be conditioned at (23 ± 5) °C and a relative humidity of
(50 ± 5) % for at least seven days before testing. Panel materials used for the test setting shall be kept in
the standard climate for at least seven days before testing.
Before beginning the testing, visually inspect the connector(s) thoroughly. Record any defects so that
they are not assumed to have been caused by the tests. Carry out measurements when specified.
NOTE For accelerating the conditioning process, EN ISO 1110 [1] can be used.
