This document specifies requirements for wire-reinforced hoses and hose assemblies of nominal sizes 6,3 to 51 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 + 125 °C, for use in underground coal mining applications. Operation at the extremes of or outside this temperature range may materially reduce the life of the hose. These hoses are not suitable for use with fluids having a castor oil or ester base.
