Hardware for furniture - Test methods 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.
This document is specifically intended for assessing 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. They do not apply to additional functions that the connector can have, e.g. covering of the connector.
The tests described in this document are carried out 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. This document 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).

Möbelbeschläge - Prüfverfahren zur Durchführung von Festigkeits- und Schwellbelastungstests von Korpuseckverbindern für Möbel aus Holzwerkstoffplatten

Dieses Dokument legt Verfahren zur Durchführung von Festigkeits  und Schwellbelastungsprüfungen für Korpuseckverbinder für Möbel, die aus Holzwerkstoffplatten bestehen, sowie Verfahren zur Auswertung der Prüfergebnisse fest.
Dieses Dokument dient speziell der Beurteilung von Korpuseckverbindern für Korpusse, die aus Holzwerkstoffplatten bestehen. 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).

Quincaillerie d'ameublement - Méthodes d'essai pour détermination de la résistance mécanique et rigidité de ferrures d'assemblage de corps de meuble

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).

Pohištveno okovje - Preskusna metoda za preskuse trdnosti in preobremenitve povezovalnih elementov za pohištvo, sestavljeno iz plošč

Ta dokument določa preskusne metode za preskuse trdnosti in preobremenitve priključnih elementov za pohištvo, izdelano iz panelnega materiala, in postopke za ocenjevanje rezultatov preskusov.
Dokument je posebej namenjen ocenjevanju povezovalnih elementov omar s trupi iz lesenih panelnih materialov. Opisane metode pa se lahko uporabijo tudi za ocenjevanje relativnih lastnosti drugih tipov povezovalnih elementov, tj. nekatere vrste povezovalnih elementov za postelje.
Preskusi trdnosti in preobremenitve se uporabljajo samo za povezovalne elemente in njihove sestavne dele ter za pritrditev v trup omare.  Ne uporabljajo se za morebitne dodatne funkcije povezovalnih elementov, npr. pokrove povezovalnih elementov.
Opisani preskusi se izvajajo v skladu s preskusnimi nastavitvami in s predpisanimi lastnostmi.
Rezultati preskusa veljajo le za preskušene povezovalne elemente. Rezultati se lahko uporabijo za predstavitev lastnosti proizvodnih modelov, če preskusni model ustreza proizvodnemu modelu.
Staranje ter vplivi temperature in vlage niso vključeni. Standard vsebuje štiri informativne dodatke, ki podajajo dodatne metodologije za podrobno oceno rezultatov preskusa, in postopek za primerjavo preskušanega povezovalnega elementa z referenčnim.
Dodatek A (informativni) – referenčni povezovalni element – lepljeni moznik
Dodatek B (informativni) – ustvarjanje razmerja
Dodatek C (informativni) – izračun togosti za nadaljnje ocenjevanje preobremenitve
Dodatek D (informativni) – ocenjevanje po značilni vrednosti (5 percentilov)

4 General test conditions
4.1 Preliminary preparation
The connectors(s) shall be mounted according to the instructions of the manufacturer.
If mounting or assembly instructions are not supplied, or if different mounting positions of the connector
are possible, the most adverse configuration shall be used and the mounting or assembly method shall be
recorded in the test report.
Connectors shall be tightened to the manufacturer’s defined torque before testing and shall not be re-
tightened unless specifically required in the manufacturer's instructions. In case the torque is not
specified by the manufacturer, the connectors are tightened to 80 % of the maximum torque or to any
other reasonable value. The torque value shall be recorded in the report. Even if the configuration is to
be changed to produce the worst-case conditions this shall be recorded in the test report.
The design of the test specimens and test equipment shall not influence the test results and shall be
adjusted if necessary. Adjustments of the test specimens or the test equipment shall be recorded in the
test report.
