This European Standard specifies requirements for two types of thermoplastic multi-layer (non-vulcanized) transfer hoses and hose assemblies for carrying liquefied petroleum gas and liquefied natural gas. Each type is subdivided into two classes, one for onshore duties, and the other for offshore.

This European Standard is applicable for hose sizes from 25 mm to 250 mm, working pressures from 10,5 bar to 25 bar and operating temperatures from - 196 °C to + 45 °C.

NOTE Offshore LNG hose assemblies are also specified in EN 1474–2.

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, associated 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.

This document 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).

1) 1 bar = 0,1 MPa.

NOTE 1 This document 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 document can be agreed with the manufacturer.

NOTE 4 This document 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 document does not apply to hose assemblies for:

— aircraft refuelling (EN ISO 1825);

— fuel dispensing (EN 1360);

— oil burners (EN ISO 6806);

— refrigerant circuits;

— fuel truck delivery (EN 1761);

— liquid petroleum gases (LPG) (EN 1762, EN 16436-2);

— fire-fighting (EN ISO 14557);

— oil suction and discharge (EN 1765);

— rotary drilling (EN ISO 6807);

— fuel dispensing with vapour recovery systems (EN 13483);

— anhydrous ammonia (EN ISO 5771).

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

 

1) 1 bar = 0,1 MPa.
