scope:

This European Standard specifies requirements for four types of thermoplastic multi-layer (non-vulcanized) hoses and hose assemblies for carrying hydrocarbons, solvents and chemicals. It specifies bore sizes from 25 mm to 300 mm, working pressures from 4 bar1) to 14 bar and working temperatures from -30 °C to 150 °C. Type 1 hoses are suitable for vapour applications. Types 2 to 4 hoses are suitable for liquid applications. The manufacturer should be consulted where a polymeric coated internal wire is being considered for use with low conductivity hydrocarbons or chemicals. This European Standard does not apply to hoses and hose assemblies for: Aircraft ground fuelling and defuelling - (EN ISO 1825); Fuel dispensing - (EN 1360); Oil burners - (EN ISO 6806); Liquefied petroleum gas and liquefied natural gas - (EN 13766); Fire fighting - (EN ISO 14775); Offshore liquefied natural gas - (EN 1474-2); Refrigeration circuits
