DESCRIPTION
BS ISO 6805:2020
This standard BS ISO 6805:2020 Rubber hoses and hose assemblies for underground mining. Wire-reinforced hydraulic types for coal mining. Specification is classified in these ICS categories:
- 83.140.40 Hoses
- 73.100.30 Equipment for drilling and mine excavation
This document specifies requirements for wire-reinforced hoses and hose assemblies for underground coal mining applications of nominal sizes 6,3 to 51 for use with:
-
oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743-4 at temperatures ranging from ?40 °C to +120 °C;
-
water-based fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743-4 at temperatures ranging from ?40 °C to +70 °C;
-
water at temperatures ranging from 0 °C to +70 °C.
There is a possibility that operation at the extremes of or outside these temperature ranges materially reduce the life of the hose. These hoses are not suitable for use with fluids that have a castor oil or ester base.
