Rubber and plastics hoses and hose assemblies - Non-bonded fluoroplastic lined (e.g. PTFE) hoses and hose assemblies for liquid and gaseous chemicals - Specification

pending
Organization: DS
Status: pending
Page Count: 43
ICS Code (Hoses and hose assemblies): 23.040.70
scope:

This European Standard 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". The hose assemblies are intended for use with chemicals conveyed in the temperature range of -70 degrees C to +260 degrees C at a working pressure of up to 360 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 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 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 materials 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 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 applicable), braid reinforcement and cover (if applicable) related to the chemical(s) to be conveyed by the hoses and hose assemblies.
