RS ISO 5149-2:2014/Amd 1:2020
Refrigerating systems and heat pumps — Safety and environmental requirements — Part 2: Design, construction, testing, marking and documentation

Abstract

This part of ISO 5149 is applicable to the design, construction, and installation of refrigerating systems,
including piping, components, materials, and ancillary equipment directly associated with such systems,
which are not covered in ISO 5149-1, ISO 5149-3, or ISO 5149-4. It also specifies requirements for testing,
commissioning, marking, and documentation. Requirements for secondary heat-transfer circuits are
excluded except for any safety devices associated with the refrigerating system.
This part of ISO 5149 is applicable to new refrigerating systems, extensions or modifications of already
existing systems, and for used systems, being transferred to and operated on another site.
This part of ISO 5149 applies to:
a) refrigerating systems, stationary or mobile, of all sizes including heat pumps;
b) secondary cooling or heating systems;
c) the location of the refrigerating systems;
d) replaced parts and added components after the adoption of this part of ISO 5149, if they are not
identical in function and in capacity.
This part of ISO 5149 does not cover “motor vehicle air conditioners”. It does not apply to goods in
storage, with respect to spoilage or contamination, but it also applies in the case of the conversion of a
system for another refrigerant.
