What is this standard about?
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.
