BS EN 16643:2016EN 16643:2016 (E) 6 Introduction This document has
30、been prepared to provide minimum acceptable requirements for the satisfactory performance of non-bonded flexible fluoroplastic lined hoses and hose assemblies with various types of reinforcement, for each chemical substance conveyed. BS EN 16643:2016EN 16643:2016 (E) 7 1 Scope This European Standard
31、 specifies requirements for three types of non-bonded fluoroplastic lined hoses and hose assemblies with convoluted or smooth linings designed to convey liquid or gaseous chemical substances, hereinafter termed the “chemicals conveyed”. These hoses and hose assemblies can be used for pharmaceutical,
32、 biotechnology and industrial applications as detailed in Clause 5. The hose assemblies are intended for use with chemicals conveyed 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
33、ensure that users are not exposed to danger from fire or explosion and that the environment is protected against contamination or damage. 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
34、to Clause 8, the hose and hose assembly performance requirements conform to Clause 9 and the hose assembly electrical properties conform 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 ma
35、terials conform to Clause 8, the hose and hose assembly performance requirements conform to Clause 9 and the hose assembly electrical 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
36、Annex G concerning the working temperature range which can be affected by the chemical(s) to be conveyed in the hoses and hose assemblies. 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 appli
37、cable), braid reinforcement and cover (if applicable) related to the chemical(s) to be conveyed by the hoses and hose assemblies. 2 Normative References The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

NOTE In this document the word “fitting” has been used; this is, in some cases, interchangeable with the word “coupling”. 3.1 non-bonded hose construction where different layers in the hose wall (e.g. lining, braid reinforcement and cover) are not chemically bonded together 3.2 Grade I ho
44、se assembly constructed so that it is electrically insulating e.g. 108 per assembly between end fittings, AND 108 between lining and end fittings AND 108 between cover and end fittings 4 Classification Hoses and hose assemblies for this application shall be divided into three types according to how
45、the hose fluoroplastic lining is constructed/formed: Type SE smoothbore (externally smooth): the hose lining is internally and externally smooth (parallel) in this document referred to as Smoothbore (externally smooth). Type SC smoothbore (externally convoluted): the hose lining is internally smooth
46、 and externally convoluted in this document referred to as Smoothbore (externally convoluted). Type C convoluted or corrugated: hose lining is internally and externally convoluted with the convolution running helically to the lining axis. Hoses and hose assemblies for this application shall be divid
47、ed into eight grades: Grade I: electrically insulated (no electrical bonding AND no static-dissipative layers), Grade M: electrically bonded without static-dissipative lining or cover, Grade -L: static-dissipative lining without electrical bonding, Grade -C: static-dissipative cover without electric
