EN 14175-2:2003 (E)3ForewordThis document (EN 14175-2:2003) 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of an identical text orby endorsement, at the latest by November 2003, and conflicting national standards shall be withdrawn at the latestby November 2003.This part of EN 14175 is applicable from the date of publication (DOP).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 fume cupboards complying with anational standard in Europe until DOP, this part of EN 14175 or the national standard may be applied until DOP + 6months.This part of EN 14175 is not applicable to fume cupboards which have been installed in the workplace 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)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 14175-2:2003 (E)4IntroductionThe performance of a fume cupboard can be expressed conveniently in qualitative terms as the ability to containand remove a pollutant or pollutants released from a source within the workspace of the fume cupboard, as well asthe ability to minimise possible perturbing influences, such as air draughts, operator movement, personnel traffic.This is effected by an inward airflow through its opening, reducing risk to the operator and other personnel which isthe primary function of this type of protective device. Other important performance criteria are the protection againstsplashes, dangerous atmospheres and the effects of implosions.The safety requirements given in this part 2 of the European Standard provide a guideline for the construction offume cupboards and serve as basis for testing of fume cupboards.Two different procedures to investigate the safety and performance are available:a)type testing in accordance with the requirements given in this part 2 and the test methods given in part 3 of thisEuropean Standard;b)testing on-site in accordance with the requirements given in this part 2 and the test methods given in part 4 of this European Standard. This on-site testing investigates an individual fume cupboard in its particular environment and does not constitute a type test. The results cannot be transferred to further production of the design or model of the fume cupboard concerned.1 ScopeThis part 2 of EN 14175 specifies safety and performance requirements and objectives for general purpose fumecupboards. In addition, dimensions and marking of general purpose fume cupboards are specified as well asrequirements on the product manual to be supplied with fume cupboards.Recommendations on the evaluation of conformity of general purpose fume cupboards with the requirements ofthis part 2 of EN 14175 are given in the informative annex A.For terms and definitions of fume cupboards EN 14175-1 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 fume cupboards for carrying outwork on radioactive materials. For special purpose fume cupboards other requirements may apply.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.
