Abstract

This Uganda Standard outlines safety requirements for protecting individuals and property, environmental guidelines, and operational procedures for refrigerating systems. It categorizes and sets criteria for selecting refrigerating systems and heat pumps, which are further detailed in ISO 5149-2, -3, and -4. The standard applies to all sizes of stationary or mobile refrigerating systems and heat pumps, as well as secondary cooling or heating systems, specifying their permissible locations. It covers replacement parts and additional components that differ in function or capacity from those originally adopted under this standard. Excluded are vehicle air conditioning systems governed by separate standards like ISO 13043 and SAE J 639. ISO 5149 applies to new systems, extensions, modifications, and relocated used systems, including conversions to different refrigerants. Standardizing refrigerating appliances and heat pumps ensures safety, enhances performance and efficiency, promotes interoperability, assures quality, addresses environmental concerns, protects consumers, and supports regulatory compliance? The standard has the below amendments that need to be adopted alongside. This standard was Published on 2025-09-30
