ARI standards establish rating criteria and procedures for measuring and certifying product performance. In this way, products are rated on a uniform basis so that buyers and users can properly make selections for specific applications.
By adding free standards on the Internet, ARI says its manufacturer members want to make it easier for contractors, architects, and engineers to make choices based on easily accessed testing and rating information.
Standard 470-2002 for desuperheater/water heaters provides definitions, test requirements, rating requirements, minimum data requirements for published ratings, marking and nameplate data, and conformance conditions. This standard applies to desuperheater/water heaters supplied as separate components and using single component and azeotropic refrigerants only.
ARI Standard 480-2001 for remote type refrigerant-cooled liquid coolers provides definitions, test requirements, rating requirements, minimum efficiency requirements for published ratings, marking and nameplate data, and conformance conditions. This standard applies to remote type
refrigerant-cooled liquid coolers of the shell-and-tube, shell-and-U-tube, shell-and-coil, and tube-in-tube types using single component and azeotropic refrigerants only.
