Furniture - Bunk beds and high beds - Part 2: Test methods
This European Standard specifies test methods for the safety, strength and durability of bunk beds and high beds for domestic and non-domestic use. The loads and forces in the strength and durability tests apply to beds with an internal length greater than 140 cm and a maximum bed base width of 120 cm. The tests are designed to be applied to a bed that is fully assembled and ready for use. The applicable safety requirements are given in EN 747-1.
Möbel - Etagenbetten und Hochbetten - Teil 2: Prüfverfahren
Dieser Europäische Norm-Entwurf legt Prüfverfahren zur Sicherheit, Festigkeit und Dauerhaltbarkeit von Etagenbetten und Hochbetten fest. Die für die Festigkeits und Dauerhaltbarkeitsprüfungen festgelegten Belastungen und Kräfte gelten für Betten mit einer inneren Länge von mehr als 140 cm und einer Höchstbreite des Bettbodens von 120 cm.
Dieses Dokument gilt nicht für Etagenbetten und Hochbetten für besondere Zwecke, einschließlich, aber nicht begrenzt auf Gefängnisse, Kasernen und Feuerwachen.
Die Prüfungen sind an einem vollständig zusammengebauten und gebrauchsfertigen Bett durchzuführen.
Die Prüfergebnisse gelten nur für den geprüften Gegenstand. Falls die Prüfergebnisse auf andere, gleich-artige Gegenstände angewendet werden sollen, muss das Prüfmuster repräsentativ für das Produktions-modell sein.
Die entsprechenden Sicherheitsanforderungen sind in prEN 747-1 angegeben.
Meubles - Lits superposés et lits surélevés - Partie 2: Méthodes d'essai
La présente Norme européenne spécifie des méthodes d’essai pour évaluer la sécurité, la résistance et la durabilité des lits superposés et des lits surélevés. Les charges et forces spécifiées pour les essais de résistance et de durabilité s’appliquent aux lits de longueur interne supérieure à 140 cm et dont le sommier à une largeur maximale de 120 cm.
La présente Norme européenne ne s’applique pas aux lits superposés et lits surélevés à usage spécial, notamment ceux destinés à être utilisés en environnement carcéral ou militaire, ou à usage du corps des sapeurs-pompiers.
Les essais sont conçus pour être appliqués à un lit entièrement assemblé et prêt à l’emploi.
Les résultats d’essai ne sont valables que pour l’article soumis à l’essai. Lorsque les résultats d’essai doivent être appliqués à d’autres articles similaires, l’échantillon doit être représentatif du modèle de production.
Les exigences de sécurité associées sont stipulées dans la prEN 747-1.

Introduction
This part of EN 747 describes a number of tests consisting of the application, to various parts of bunk beds
and high beds, of loads or forces applied by one adult occupant per bed during normal functional use. It also
deals with misuses that can be reasonably expected to occur.
The tests are designed to evaluate properties without regard for materials, design/construction or
manufacturing processes.

1 Scope
This European Standard specifies test methods for the safety, strength and durability of bunk beds and high
beds for domestic and non-domestic use. The loads and forces in the strength and durability tests apply to
beds with an internal length greater than 140 cm and a maximum bed base width of 120 cm.
The tests are designed to be applied to a bed that is fully assembled and ready for use.
The applicable safety requirements are given in EN 747-1.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.
EN 747-1:2012, Furniture — Bunk beds and high beds — Part 1: Safety, strength and durability requirements
EN ISO 2439:2008, Flexible cellular polymeric materials — Determination of hardness (indentation technique)
(ISO 2439:2008)
3 General test conditions
3.1 Preliminary preparation
For furniture that includes hygroscopic materials, at least one week in normal indoor conditions shall have
elapsed between manufacturing (or assembly) and testing.
For all other furniture, at least 48 hours in normal indoor conditions shall have elapsed prior to testing.
The sample shall be tested as delivered. If the sample is a knock-down type, it shall be assembled according
to the instructions supplied with it. If the instructions allow for different combinations, the most adverse
combination shall be used for each test.
Samples intended to be fastened together in pairs or attached to the structure of a building shall be tested as
single, free-standing samples unless the instructions specifically require attachment to another sample or the
building structure.
The test shall be carried out in indoor ambient conditions at a temperature between 15 °C and 25 °C. If, during
a test, the temperature falls outside of the range of 15 °C to 25 °C, the maximum and/or minimum temperature
shall be recorded in the test report.
Knock-down fittings shall be tightened before testing and shall not be re-tightened throughout the testing
procedures.
The tests shall be carried out on the same sample and following the order of the clauses of EN 747-1. If a test
cannot be carried out as specified in this standard, e.g. because a loading pad cannot be used for the
application of a force due to the design of the product, the test shall be carried out as closely as possible to
the specified procedure.
3.2 Application of forces
The test forces in durability and static load tests shall be applied sufficiently slowly to ensure that negligib
