This International Standard specifies requirements for rubber hoses and hose assemblies for use in oil burners. Such hose assemblies should not be used, without special assessment, for purposes other than oil burner installations.
Two types of hose assemblies are specified:
— Type 1: Hose assemblies for flux and reflux, but not for insertion between the oil burner pump and the atomizing connection; maximum working pressure 1,0 MPa (10 bar); maximum oil temperature of 100 °C.
— Type 2: Hose assemblies for insertion between the oil burner pump and the atomizing connection; working pressure 4,0 MPa (40 bar); maximum oil temperature of 100 °C.
