ISO 5149-3:2014
Refrigerating systems and heat pumps — Safety and environmental requirements — Part 3: Installation site
ISO 5149-3:2014 is applicable to the installation site (plant space and services). It specifies requirements for the site for safety, which could be needed because of, but not directly connected with, the refrigerating system and its ancillary components.
ISO 5149-3:2014 is applicable to new refrigerating systems, extensions or modifications of existing systems, and for used systems being transferred to and operated on another site. It also applies in the case of the conversion of a system for another refrigerant.
