This International 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. — Class A hose is for use onshore. — Class B hose is for use offshore. This International 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, according to class. NOTE Offshore LNG hose assemblies are also specified in EN 1474–2.
