EN 1264系列给出了安装在建筑物、住宅和非住宅（如办公、公共、商业和工业建筑）中的表面嵌入式加热和冷却系统的指南，并侧重于为热舒适目的安装的系统。 EN 1264系列给出了嵌入待加热或待冷却房间外壳表面的水基加热和冷却系统的指南。它还规定了使用其他加热介质代替水，视情况而定。 EN 1264系列通过计算和测试技术规范和认证的加热热输出，规定了标准化的产品特性。关于这些系统的设计、构造和操作，见EN 1264-3和EN 1264-4中A、B、C、D、H、I和J型。对于E、F和G型，见EN ISO 11855系列。 EN 1264系列中规定的系统与建筑物外壳表面的结构基座相连，直接安装或用固定支架安装。 EN 1264系列没有规定安装在吊顶内的吊顶系统，该吊顶系统和建筑结构之间设计有开放的空气间隙，允许热诱导空气循环。这些系统的热输出可根据EN 14037系列和EN 14240确定。 EN 1264-5规定了重新计算EN 1264-2中确定的有关系统的值。它可以将EN 1264-2的计算和测量结果转换为室内其他表面方向的结果，即天花板和墙壁加热，以及作为冷却表面的应用，即地板、天花板和墙壁冷却。EN 1264-2的试验结果是所有计算的基础，无论该系统是否用于加热或冷却应用。

The EN 1264 series gives guidelines for surface embedded heating and cooling systems installed in buildings, residential and non-residential (e.g. office, public, commercial and industrial buildings) and focuses on systems installed for the purpose of thermal comfort. The EN 1264 series gives guidelines for water based heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. It also specifies the use of other heating media instead of water, as appropriate. The EN 1264 series specifies standardized product characteristics by calculation and testing the thermal output of heating for technical specifications and certification. For the design, construction and operation of these systems, see EN 1264-3 and EN 1264-4 for the types A, B, C, D, H, I and J. For the types E, F and G, see the EN ISO 11855 series. The systems specified in the EN 1264 series are adjoined to the structural base of the enclosure surfaces of the building, mounted directly or with fixing supports. The EN 1264 series does not specify ceiling systems mounted in a suspended ceiling with a designed open air gap between the system and the building structure which allows the thermally induced circulation of the air. The thermal output of these systems can be determined according to the EN 14037 series and EN 14240. EN 1264-5 specifies the recalculation of values determined in EN 1264-2 for the system in question. It enables the conversion of the calculation and measurement results of EN 1264-2 into results for other surface orientations in the room, i.e. for ceiling and wall heating, as well as for the application as cooling surfaces, i.e. for floor, ceiling and wall cooling. The test results of EN 1264-2 are the basis of all calculation, whether or not the system in question is used for heating or cooling application.
