This International Standard specifies the minimum requirements for rubber hoses used for transferring ammonia, in liquid or in gaseous form, at ambient temperatures from −40 °C up to and including +55 °C at a working pressure of 2,5 MPa (25 bar). It does not include specifications for end fittings, but is
limited to the performance of the hoses and hose assemblies.

This document specifies the minimum requirements for rubber hoses and hose assemblies for use in oil burners.
The following two types of hose assembly 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
100 °C.
— Type 2: Hose assemblies for insertion between the oil burner pump and the atomizing connection;
maximum working pressure 4,0 MPa (40 bar); maximum oil temperature 100 °C.
The hose assemblies specified in this document are not intended to be used, without special assessment, for purposes other than oil burner installations.
