Office furniture - Work tables and desks - Part 3: Methods of test for the determination of the stability and the mechanical strength of the structure

This part of the European standard EN 527 specifies the mechanical strength requirements and test methods of the structure of tables and desks. The tests are designed to be applied to an article of furniture that is fully assembled and ready for use.

Büromöbel - Büro-Arbeitstische - Teil 3: Prüfverfahren für die Bestimmung der Standsicherheit und der mechanischen Festigkeit der Konstruktion

Dieser Teil der Europäischen Norm EN 527 legt Prüfverfahren für die Bestimmung der Standsicherheit und der mechanischen Festigkeit der Konstruktion von Büro Arbeitstischen fest.
ANMERKUNG   In der englischen Fassung der Norm haben die Benennungen "table" und "desk" die gleiche Bedeutung und zur Vereinfachung wird dort im weiteren Verlauf der Norm nur noch die Benennung "table" verwendet.
Die Prüfungen sind zur Anwendung am vollständig zusammengebauten und gebrauchsfertigen Möbel ausgelegt.

Mobilier de bureau - Tables de travail de bureau - Partie 3: Méthodes d'essai pour la détermination de la stabilité et de la résistance mécanique de la structure

La présente partie de l'EN 527 spécifie un ensemble de méthodes d'essai méca- niques de résistance de la structure des tables et bureaux ainsi que les spécifications correspondantes. Les essais sont conçus pour etre appliqués a un meuble entierement assemblé et pret a l'usage.

EN 527-3:2003 (E)41 ScopeThis part of EN 527 specifies methods of test for the determination of the stability and the mechanical strength ofthe structure of office work tables and desks.NOTEIn this standard, the words « table » and « desk » have the same meaning. For simplicity, only the word « table » isused in the remainder of the standard.The tests are designed to be applied to an article of furniture that is fully assembled and ready for use.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies.ISO 48:1994, Rubber, vulcanized or thermoplastic – Determination of hardness (hardness between 10 IRHD and100 IRHD).3 General test conditions3.1 Preliminary preparationBefore any of the tests are commenced, the item shall be old enough to ensure that it has developed its fullstrength.The furniture shall be tested as delivered. Knock-down furniture shall be assembled according to the instructionssupplied with it. If the furniture can be assembled, adjusted or combined in different ways, the most adversecombination shall be used for each test. Knock-down fittings shall be tightened before testing and shall not be re-tightened unless specifically required by the manufacturer.The tests shall be carried out in indoor ambient conditions at a temperature between 15°C and 25°C.The test forces in durability and static load tests shall be applied sufficiently slowly to ensure that negligibledynamic load is applied. The forces in fatigue tests shall be applied sufficiently slowly to ensure that kinetic heatingdoes not occur.The forces can be replaced by masses.3.2 Determination of the drawer test loadThe test load of drawers, M, is defined by the following formula :5230050330,)(´´´=hLlkgM.where :l (in mm) is the internal width : usable distance between the sides of the drawer.L (in mm) is the internal
