本标准提供测试或计算方法，以评估在正常最终使用条件下定制的步入式冷室和部件的保温性能。 步入式冷室的正常最终使用条件被认为是: - 安装在现有建筑物内; - 不暴露于外部天气条件; - 面板内部温度在指示范围内-40°C〜¤¤12°C; - 面板的外部面温度在指示范围内-8°C¤¤30°C;温度低于0°C或高于20°C时，如果步入式冷藏室位于空调处所内，则可能会达到。 注意如果在中等储存温度下工作的定制步入式冷藏室用作食品加工室或洁净室，则应用标准

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.
