1 Scope This International Standard specifies requirements for six types of embedded-wire hose and hose assembly of bore diameter from 5 mm to 51 mm for use with common hydraulic fluids such as mineral oils, soluble oils, oil and water emulsions, aqueous glycol solution and water at temperatures ranging from − 40 °C to + 100 °C for types 1 to 5 and from − 40 °C to + 121 °C for type 6. Operation at the extremes of or outside this temperature range may materially reduce the life of the hose. The hose is not suitable for use with fluids having a castor oil or ester base.
