EN 14175-1:2003 (E)3ForewordThis document (EN 14175-1:2003) 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of an identical text orby endorsement, at the latest by November 2003, and conflicting national standards shall be withdrawn at the latestby November 2003.This part of EN 14175 is applicable from the date of publication (DOP). For placing on the market of fumecupboards at DOP complying with a national standard in Europe, this part of EN 14175 or the national standardmay be applied until DOP + 6 months.This part of EN 14175 is not applicable to fume cupboards which have been installed in the work place before DOP+ 6 months if not otherwise declared by the manufacturer.EN 14175 consists of the following parts, under the general title Fume cupboards Part 1: Vocabulary Part 2: Safety and performance requirements Part 3: Type test methods Part 4: On-site test methods Part 5: Recommendations for installation and maintenance (in preparation) Part 6: Variable air volume fume cupboards (in preparation)Attention is drawn to the addition and modification of terms given in prEN 14175-3:2003.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 14175-1:2003 (E)4IntroductionThe objective of this part 1 of EN 14175 is to give definitions for terms relevant to fume cupboards for general use.The terms and their definitions offer assistance in the construction of fume cupboards, in the drafting of userinformation as well as in the testing of fume cupboards. They are intended to contribute towards mutualunderstanding amongst manufacturers, laboratory designers, users and health and safety authorities.Terms which occur the first time in the definition of another term of this European standard are printed in bold type.1 ScopeThis part 1 of EN 14175 provides terms and definitions for fume cupboards (see 3.1). Corresponding terms in eightEuropean languages are given in the normative annex A.For safety and performance requirements of fume cupboards EN 14175-2 applies.For type testing of fume cupboards prEN 14175-3 applies.For microbiological safety cabinets EN 12469 applies.This part of EN 14175 does not address recirculatory filtration fume cupboards or devices used as animalaccomodation.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).3 Types of fume cupboards3.1fume cupboardsprotective device to be ventilated by an induced flow of air through an adjustable working opening with an enclosure designed to limit the spread of airborne contaminants to operators and other personneloutside the device, offering a degree of mechanical protection, and providing for the controlled release of airborne contaminantsNOTEA fume cupboard is a ventilated enclosure complying with the requirements specified in EN 14175-2.
