Defines the minimum requirements for rubber hoses used for transferring ammonia, in liquid or in gaseous form, at ambient temperatures from -40 degree C up to and including +55 degree C.

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. It does not include specifications for end fittings, but is limited to the performance of the hoses and hose assemblies.
