ISO 18566-3:2017规定了天花板安装辐射板的设计。 ISO 18566-3:2017适用于住宅、商业和工业建筑中的水基加热和冷却面板系统（自由悬挂）。这些方法适用于安装在具有开放空气间隙的天花板结构上的系统。 ISO 18566-3:2017适用于作为房间外围一部分的所有类型的预制辐射板。 ISO 18566-3:2017不包括嵌入天花板、墙壁或地板结构的面板，这些面板没有开放的空气间隙和混合（热辐射和强制对流组合）天花板面板。

ISO 18566-3:2017 specifies the design of ceiling mounted radiant panels. ISO 18566-3:2017 is applicable to water-based heating and cooling panel systems (free hanging) in residential, commercial and industrial buildings. The methods apply to systems mounted to the ceiling construction with an open air gap. ISO 18566-3:2017 applies to all types of prefabricated radiant panels that are part of the room periphery. ISO 18566-3:2017 does not cover panels embedded into ceiling, wall or floor structures without open air gap and hybrid (combined thermal radiation and forced-convection) ceiling panels.
