This document 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 25mm to 300mm, working pressures from 0,4MPa (4bar) to 1,4MPa (14bar) and working temperatures from 30C to 150C, according to type.
Type1 hoses are suitable for vapour applications. Types2 to4 hoses are suitable for liquid applications.
NOTE1 See AnnexA concerning the selection of the material for the inner wall of layers and any polymeric coating of the internal wire helix related to the chemical(s) to be conveyed by the hoses and/or hose assemblies.
NOTE2 It is intended that the manufacturer be consulted where a polymeric coated internal wire is being considered for use with low conductivity hydrocarbons or chemicals.
This document does not apply to hoses and hose assemblies for:
aircraft refuelling (see ISO1825);
fuel dispensing (see ISO5772);
oil burners (see ISO6806);
liquefied petroleum gas and liquefied natural gas (see ISO27127);
