Defines requirements for two types of hose assemblies (Types D and SD) and four grades based on electrical properties with hoses made of rubber or thermoplastics and hose fittings made of metal designed to convey liquid or gaseous chemical substances, hereinafter termed the "chemicals conveyed".

This European Standard specifies requirements for two types of hose assemblies (Types D and SD) and four grades based on electrical properties with hoses made of rubber or thermoplastics and hose fittings made of metal 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 -20 °C to +65 °C at a working pressure ≤ 10 bar¹⁾.

NOTE 1 This European 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 working pressures than those given above can be agreed with the manufacturer, provided that the marking on the hose (see 14.1) states this and the requirements of Table 5 and all the other requirements are met.

NOTE 3 Other diameters than those given in this European Standard can be agreed with the manufacturer.

NOTE 4 This European Standard also provides guidance on the storage of hose assemblies (Clause 15).

NOTE 5 The attention of users is drawn to Annex F concerning the selection of lining material related to the chemical(s) to be conveyed by the hoses and/or hose assemblies.

This standard does not apply to hose assemblies for:

• aircraft refuelling (EN 1361);

• fuel dispensing (EN 1360);

• oil burners (EN ISO 6806);

• refrigerant circuits;

• fuel truck delivery (EN 1761);

• liquid petroleum gases (LPG) (EN 1762);

• fire fighting (EN ISO 14557);

• oil suction and discharge (EN 1765);

• rotary drilling (EN ISO 6807);

• fuel dispensing with vapour recovery system (EN 13483).

This European Standard does not apply to multilayer hose assemblies (EN 13765 and EN 13766).
