scope:

This International standard specifies requirements for rubber hose used for transferring ammonia, in liquid or in gaseous form, at ambient temperatures between -40° C and +55° C. It does not include specifications for end fittings, but is limited to the performance of the hose and hose assemblies. It applies to hose used for transfer to or from pressure tanks or refrigerated tanks, but is not necessarily for applications where the hose is downstream from a pressure regulator and is open to the atmosphere at one end.
