Workbenches for laboratories - Dimensions, safety requirements and test methods
This draft European Standard specifies safety requirements and test methods for laboratory benches including laboratory tables and gives recommendations for their dimensions. It applies to benches, movable tables and overbench shelves designed for use in research, educational, quality control and similar laboratories. It should be understood that fulfilling the requirements do not ensure that failure will not occur as a result of habitual misuse or after an excessively long period of service. The tests are designed to be applied to a stand-alone bench that is fully assembled and ready for use.
Arbeitstische für Laboratorien - Maße, Sicherheitsanforderungen und Prüfverfahren
Dieser Europäische Norm-Entwurf legt Sicherheitsanforderungen und Prüfverfahren für Laborarbeitstische einschließlich beweglicher Tische fest und gibt Empfehlungen für ihre Maße. Diese Europäische Norm gilt für fest installierte Arbeitstische, bewegliche Tische und Tischablagen, die für den Gebrauch in Forschungs-, Ausbildungs-, Qualitätskontroll- und gleichartigen Laboratorien konstruiert sind. Diese Europäische Norm gilt nicht für Schülertische in wissenschaftlichen Klassenräumen von Schulen. Sie gilt nicht für Spezialtische, beispielsweise für schwere diagnostische Analysenautomaten oder verfahrenstechnische Maschinen. Verständlicherweise wird durch diese Norm nicht sichergestellt, dass Mängel, die infolge regelmäßigen Missbrauchs oder nach einer übermäßig langen Nutzungszeit auftreten können, vermieden werden. Die Prüfungen gelten für einen allein stehenden Arbeitstisch, der komplett montiert und betriebsfertig ist. Anforderungen und Prüfverfahren hinsichtlich der Feuersicherheit von Arbeitstischen und hinsichtlich der Wiederstandsfähigkeit der Arbeitsoberfläche sind in dieser Europäische Norm nicht behandelt.
Paillasses de laboratoire - Dimensions, spécification de sécurité et méthodes d'essai
La présente Norme européenne spécifie les prescriptions de sécurité et les méthodes d'essai des paillasses de laboratoire, y compris les tables de laboratoire et donne des recommandations concernant leurs dimensions.
La présente Norme européenne s'applique aux paillasses, tables mobiles et tablettes conçues pour une utilisation dans des laboratoires de recherche, d'enseignement, de contrôle de qualité ou similaires.
La présente norme ne s'applique pas aux paillasses pour éleves des classes scientifiques des écoles. Elle ne s'applique pas aux paillasses pour usages spéciaux, par exemple pour diagnostic lourd ou pour machines de traitement.
Il devrait etre compris que le respect des prescriptions n'assure pas qu'un défaut n'apparaisse du fait d'une mauvaise utilisation continuelle ou apres une période d'utilisation excessivement longue.
Les essais sont conçus pour etre appliqués a une paillasse isolée completement assemblée et prete a l'utilisation.
Les spécifications et méthodes d'essai liées a la sécurité des paillasses en cas d'incendie et a la résistance du plan de travail ne sont pas traitées dans la présente Norme européenne.

Up-to-date lists and bibliographical references concerning such nationalstandards may be obtained on application to the Management Centre or to any CEN member.This European Standard exists in three official versions (English, French, German). A version in any other language made by translationunder the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the officialversions.CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.EUROPEAN COMMITTEE FOR STANDARDIZATIONCOMITÉ EUROPÉEN DE NORMALISATIONEUROPÄISCHES KOMITEE FÜR NORMUNGManagement Centre: rue de Stassart, 36

For workbenches for laboratoriescomplying with a national standard before dop, this previous national standard may continue to apply forproduction and placing on the market until 2 years after dop. This standard does not apply to workbenches forlaboratories, which have been put into service in the laboratory before 2 years after dop.Annex A is normative. Annex B is informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,Switzerland and the United Kingdom.1 ScopeThis European Standard specifies safety requirements and test methods for workbenches for laboratoriesincluding laboratory tables and gives recommendations for their dimensions. This European Standard applies to workbenches, movable tables and workbench shelves designed for use inresearch, educational, quality control and similar laboratories. This European Standard does not apply to workbenches for pupils in scientific class rooms of schools. It doesnot apply to workbenches for special purposes, e.g. for heavy diagnostic or processing machines.It should be understood that fulfilling the requirements does not ensure that failure will not occur as a result ofhabitual misuse or after an excessively long period of service. The tests are designed to be applied to a stand-alone workbench that is fully assembled and ready for use.

Components or parts of the workbench with which the user may comeinto contact during intended use shall not have burrs, sharp edges or sharp corners and points.Workbenches shall be manufactured from materials which are resistant to the mechancial, chemical and thermalrequirements of the intended use of the workbench. Any vertical glass component greater than or equal to 0,06 m2 shall comply with prEN 12600:1999 type 4B or 4C.The width of accessible apertures (excluding drawers and doors and their associated fittings but including thegap between handles and other parts of the structure) shall always be either less than 8 mm or more than 25 mm. Handles shall not incorporate recesses in which substances may accumulate. Accessible open ends andfeet of tubular components shall be capped or otherwise closed.Work surfaces specifically designed to retain liquids shall be provided with retaining edges on all sides so thatthe retention capacity is min. 5 litres per square metre of work surface.Any joints and work surfaces shall be made using materials to give a surface which will not crack, retain dirt orforeign matter or absorbs liquid. When required by the intended use, special care shall be taken to ensure thatthe growth of harmful pathogenic agents will not be promoted or sustained.A retaining strip of min. 30 mm height shall be provided on the rear edges and open ends of overworkbenchshelves unless they abut a wall. When the work requires it, a separation shield shall be provided between twoopposite work surfaces. 6 Specific requirements6.1 StabilityA free standing workbench shall not overturn when tested in accordance with 6.3.6.2 Strength and durabilityThe workbench shall show no failure which can affect safety when tested as specified in 6.3 and it shall still fulfilits function. Furthermore in the deflection of workbench shelves test (see A.3.4) there shall be no deflectiongreater than span/200 under load and no permanent deflection greater than span/1000 24 hours after unloading.
