WARNING Persons using this European Standard should be familiar with normal laboratory practice. This standard does not purport to address all the safety problems, if any, as

31、sociated with its use. It is the responsibility of the user to establish appropriate health and safety practices and to ensure compliance with any national regulatory conditions. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bo

EN 16643:2016 (E) DIN EN 16643:2016-11 6 Introduction This document has been prepared to provide minimum acceptable requirements for the satisfactory performance of non-bonded flexible fluoroplastic lined hos

34、es and hose assemblies with various types of reinforcement, for each chemical substance conveyed. EN 16643:2016 (E) DIN EN 16643:2016-11 7 1 Scope This European Standard specifies requirements for three types of non-bonded fluoroplastic lined hoses and hose assemblies with convoluted or smooth linin

35、gs designed to convey liquid or gaseous chemical substances, hereinafter termed the “chemicals conveyed”. These hoses and hose assemblies can be used for pharmaceutical, biotechnology and industrial applications as detailed in Clause 5. The hose assemblies are intended for use with chemicals conveye

36、d in the temperature range of 70C to +260C and for a working pressure up to 205 bar1). NOTE 1 This standard sets out requirements for these hoses and hose assemblies to ensure that users are not exposed to danger from fire or explosion and that the environment is protected against contamination or d

37、amage. NOTE 2 Other working pressures than those given above can be agreed with the manufacturer provided the physical properties of the hose assembly materials conform to Clause 8, the hose and hose assembly performance requirements conform to Clause 9 and the hose assembly electrical properties co

38、nform to Clause 10. NOTE 3 Other diameters than those given in this standard can be agreed with the manufacturer provided the physical properties of the hose assembly materials conform to Clause 8, the hose and hose assembly performance requirements conform to Clause 9 and the hose assembly electric

39、al properties conform to Clause 10. NOTE 4 This standard also provides guidance on the storage of hose assemblies (Clause 15). NOTE 5 The attention of users is drawn to Annex G concerning the working temperature range which can be affected by the chemical(s) to be conveyed in the hoses and hose asse

40、mblies. NOTE 6 The attention of users is drawn to Annex G concerning the selection of materials for lining, helix wire (if applicable), electrical bonding wire (if applicable), braid reinforcement and cover (if applicable) related to the chemical(s) to be conveyed by the hoses and hose assemblies. 2
