This European Standard applies to prefabricated walk-in cold room kits and components. It provides test or calculation methods to assess thermal insulation performances under normal end-use conditions. Performance characteristics of walk-in cold rooms are to be assessed in terms of thermal insulating properties, in order to give a basis on which assessing energy consumption related properties of walk-in cold rooms, and of their components. Performance characteristics are to be assessed for every single component of the walk-in cold room, and for the assembled walk-in cold room as a whole. The normal end-use conditions of a walk-in cold room are considered to be: – installation inside an existing building; – not exposed to external weather conditions.
