21、ive 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 user information as well as in the testing of fume cupboards. They are intended to contribute towards mutual understanding
22、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 Scope This part 1 of EN 14175 provides terms and definitions for fume cupboards (see 3.1). Co
23、rresponding terms in eight European 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 no
24、t address recirculatory filtration fume cupboards or devices used as animal accomodation. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.
