This European standard specifies requirements for two types of hose assemblies (Types D and SD) with hoses
made of rubber or thermoplastics and hose fittings made of metal designed to convey liquid or gaseous
substances, hereinafter termed the chemicals conveyed.
For all hose assemblies, the maximum working pressure is 10 bar 1) Hose assemblies can be operated safely with
a conveyed chemical temperature in the range of -20 °C to + 65 °C.
NOTE 1 This standard sets out requirements for these 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 temperatures and pressures than those given above can be agreed with the
manufacturer.
NOTE 3 Other diameters than those given in this standard can be agreed with the manufacturer.
Typical masses and vacuum stability are listed in annex A.
NOTE 4 This standard also provides guidance on the storage of hose assemblies (see annex B).
NOTE 5 The attention of users is drawn to annex C concerning the selection of lining material related
to the chemical(s) to be conveyed by the hoses and/or hose assembly.
