EN 14056:2003 (E)3ForewordThis document (EN 14056:2003) has been prepared by Technical Committee CEN /TC 332 "Laboratoryequipment", the secretariat of which is held by DIN.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by October 2003, and conflicting national standards shall be withdrawn at the latestby October 2003.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to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, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.



EN 14056:2003 (E)41 ScopeThis European Standard gives recommendations for the installation and design of laboratory benches, storageunits and services and their connections and fittings. The recommendations may be used by all parties involved inthe design, manufacture, installation and use of a new laboratory or in the refitting of an old laboratory.NOTE 1. Attention is drawn to national regulations in respect of electricity, water and gas supply.NOTE 2. Attention is drawn to building regulations and requirements, e.g. for floor loading.NOTE 3. In the use of laboratory equipment and furniture, risk assessment and appropriate precautions are the responsibility ofthe organization running the laboratory and the laboratory user.NOTE 4. Attention is drawn to any national regulations in respect of transfer of liability during the building and installation oflaboratories.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 (including amendments).EN 12469, Biotechnology — Performance criteria for microbiological safety cabinets.EN 13150, Workbenches for laboratories — Dimensions, safety requirements and test methods.EN 61010-1,Safety requirements for electrical equipment for measurement, control, and laboratory use — Part 1: Generalrequirements (IEC 61010-1:2001).EN 14175-2, Fume cupboards — Part 2: Safety and performance requirements.3 Storage and handlingPrior to installation, furniture should be stored in a secure space and steps should be taken to minimise the risk ofdamage or deterioration. Care should be taken in protecting furniture stored or installed in the laboratory beforeand during decoration and fitting out of the laboratory. Information given by the manufacturer should be followed.The adequacy of access to the laboratory and any temporary storage space should be checked. In difficult cases,scaffolded access through windows may be necessary. Particular attention should be paid to the following:a) door dimensions;b) stairways and landings;c) elevator load and dimensions;d) corridor dimensions, changes of corridor direction and potential obstructions.Information should be exchanged between the furniture supplier and the furniture installer about the space neededfor moving the furniture into the laboratory.4 Laboratory conditions for installationThe furniture should not be installed if the air temperature or relative humidity in the laboratory to receive it issignificantly different from that of its storage space.



EN 14056:2003 (E)5If furniture has to be installed before new building work has dried out, heating and dehumidification should beapplied slowly over a number of days. Dehumidifiers should be used in preference to heaters. If heating only isapplied, good ventilation is essential.Where mobile and relocatable furniture is to be installed, all surfaces, including those to be concealed by thefurniture, should be decorated before installation. This
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;



EN 14056:2003 (E)6c) water;d) steam: steam and condensate;e) each gas;f) drainage.NOTE
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;
