ISO 5151:2017/Amd 1:2020 is an international standard that details the testing and rating procedures for non-ducted air conditioners and heat pumps. It focuses on establishing consistent methods for determining the performance of these devices, including capacity and efficiency ratings, for various residential, commercial, and industrial applications. The standard covers equipment that is factory-made, electrically driven, and uses mechanical compression for cooling and heating. The amendment (Amd 1:2020) provides updates and clarifications to the original standard.
