Mobilier de laboratoire - Recommandations de conception et d'installation

La présente Norme européenne donne des recommandations concernant l'installation et la conception des paillasses, unités de stockage et alimentations associées, et de leurs raccordements et accessoires. Ces recommandations peuvent être utilisées par toutes les parties impliquées dans la conception, la fabrication, l'installation et l'utilisation d'un nouveau laboratoire ou dans la rénovation d'un ancien laboratoire.
NOTE 1   L'attention est attirée sur le respect des réglementations nationales en matière d'alimentation en électricité, eau et gaz.
NOTE 2   L'attention est attirée sur les réglementations et exigences en matière de bâtiment, par exemple en ce qui concerne la charge des planchers.
NOTE 3   En matière d'utilisation du matériel et du mobilier de laboratoire, l'évaluation des risques et les précautions à prendre relèvent de la responsabilité de l'organisation gestionnaire du laboratoire et de l'utilisateur du laboratoire.
NOTE 4   L'attention est attirée sur les réglementations nationales relatives au transfert de responsabilité pendant la construction et l'installation du laboratoire.

minimise redecoration and making good at subsequentlayout changes.It is recommended to complete decoration and floor coverings as far as possible before furniture is installed. Wherefurniture has already been installed, it should be protected effectively from following trades prior to handover.5 Fixing floor- and wall-mounted furnitureFixed furniture items should be fixed to the floor or supporting wall by the method recommended by themanufacturer.Workbenches shall comply with EN 13150.NOTE
European standards for laboratory storage units and fume cupboards are in development.Floor-mounted bench substructures of the cupboard pedestal or leg frame type should include a provision forlevelling the worktop. A similar provision should be included with wall-mounted furniture. Worktops should beprovided with upstands in order that the junction with the wall is located above the general work surface.If floor covering is to be coved to the furniture, forming a continuous upstand to facilitate cleaning anddecontamination, fixed floor furniture may need to be installed before floor covering is laid.When fixing laboratory furniture, care should be taken to facilitate cleaning.6 Placing mobile and relocatable furnitureMobile furniture should be fitted with a locking device and relocatable furniture should be fitted with a levellingdevice.Having placed mobile and relocatable furniture in the required positions, these devices should be adjusted toachieve a neat level and line of all components in grouped arrangements. Components should be fixed inaccordance with the manufacturer’s instructions.7 Height adjustable furnitureHeight adjustable furniture should have a means of adjustment, levelling and locking.8 Services distribution zone in furnitureLaboratory furniture layouts should include ‘spine’ zones for services distribution.Generally a building service distribution run should not be located in the laboratory furniture spine if it continues onto service other areas of the building.Services should be grouped and coded under the following types:a) electrical: lighting and power;b) communications;

Attention is drawn to national regulations or standards that may apply.Pipes for cold water and steam should have a thermal insulation. All pipes should be fixed in such a way that theirdeformation during use does not occur.9 Services inputThe location of building services supply connection points
depends on the furniture configuration. Electricalconnections in the floor should be avoided.NOTE
Floor connections may impose severe restrictions on the rearrangement of services and furniture, unless the laboratoryhas a raised access floor, duct, service void or some similar arrangement.Wall connections should be easily accessible.The provision of a services bollard should be considered where equipment is mobile.Consideration should be given to the provision of the following:a) access space for service entry, connection and maintenance;b) means of isolating branch or bench from supply. Ideally, isolation and protection points should be locatedadjacent to the exit from the laboratory. Overhead multi-user or teaching environments may necessitatealternatives. Siting an interface at each bench or group offers the advantage of local isolation which
does notdisturb nearby benches;c) protection for personnel, e.g. by suitably rated residual current devices or circuit breakers, ‘knock-off’ button,gas or steam valves, pressure-reducing valves.Separation facilities to be considered for individual services can be as follows:1) Ventilation. No special facilities;2) Water. Isolation with a valve or stopcock of suitable materials;3) Waste. Isolation by siphon or dilution chamber;4) Steam. Isolation with a valve or stopcock of suitable materials;5) Gases: general. Isolation and pressure reduction to a level safe for use at bench or fume cupboard outlets.Pressure reduction should occur as near as possible to the source of supply within the laboratory;6) Gases: combustible. Main stopcock control accessible at exit door of laboratory;7) Gases: special. Isolation and pressure reduction to a level suitable for the apparatus in use. Pressurereduction should occur as near as possible to the source of supply within the laboratory. Flow limitation isrecommended for hazardous gases. For hazardous gases, it is also recommended that the outlet from thesafety valve and diaphragm on the pressure reducing valve leads to a safe place outside the building. Finalfiltration of high purity gases may be provided for the protection of the apparatus served;

Attention is drawn to national regulations.9) Communications. With regard to communication and data transmission lines, electromagnetic compatibilityshould be observed.10 Installing servicesAllowance should be made for a degree of misalignment between the location of building services terminations andthe furniture that relates to them.For electrical power and telecommunications, tolerance is provided by the flexibility of cabling and wiring. If thesituation demands, conduiting cabling should be considered with piped services.Fixed furniture requires a different design approach from that of mobile and relocatable furniture.Service connections for fixed furniture may be either:a) a rigid hand crafted junction pipe or conduit formed to take up any discrepancy between the location ofbuilding site services terminations in furniture; orb) a flexible junction pipe or conduit adjusted to take up any discrepancy as above.For mobile furniture assemblies, the use of flexible service connections is essential to allow for movement and tofacilitate relocation. The length of flexible service connections should be related to the grid of services outlets onthe building site where such a grid is provided for future relocation and reconnection of furniture and equipment.11 Service outlets11.1 Bench level outlets11.1.1 GeneralBench outlets sho
