This document provides test or calculation methods to assess thermal insulation performances for customized walk-in cold rooms and components under normal end-use conditions. 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; – internal side of panels subject to temperatures within the indicative range ?40 °C ? T ? 12 °C; – external side of panels subject to temperatures within the indicative range ?8 °C ? T ? 30 °C; temperatures below 0 °C, or higher than 20 °C, can be reached if the walk-in cold room is located inside not air-conditioned premises. NOTE In case the customized walk-in cold room working at positive storage temperature is used as a food processing room or a clean room, the standard is applied.
