BS EN 13766:2010EN 13766:2010 (E) 4 1 Scope 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 s

21、ubdivided 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

22、 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 a

23、nd to ensure compliance with any national regulatory conditions. 2 Normative references The following referenced documents are indispensable for the application of this document.
