5 Introduction This European Standard results from the recognition, that heated and chilled ceiling radiant panels falling into the field of application hereinafter stated are traded on the basis of their thermal output. For evaluating and comparing different heated and chilled ceiling surfaces it is therefore necessary to refer to a heating stipulated value. As installations with ceiling mounted radiant panels can also be used in practice for space cooling, it is nec-essary to have a test method for evaluating the cooling capacity. Installations with different free hanging heating and cooling surfaces need, for the use of space heating a test method for evaluating the heating out-put. The test method differs from the method for ceiling mounted radiant panels. The European Standard EN 14037, Free hanging heating and cooling surfaces for water with a temperature below 120°C, consists of the following parts: — Part 1: Pre-fabricated ceiling mounted radiant panels for space heating - Technical specifications and re-quirements; — Part 2: Pre-fabricated ceiling mounted radiant panels for space heating - Test method for thermal output; — Part 3: Pre-fabricated ceiling mounted radiant panels for space heating - Rating method and evaluation of radiant thermal output; — Part 4: Pre-fabricated ceiling mounted radiant panels for space heating - Test method for cooling capacity; — Part 5: Open or closed heated ceiling surfaces - Test method for thermal output.

6 1 Scope This European Standard defines technical specifications and requirements of free hanging pre-fabricated ceiling mounted radiant panels with an air gap between construction and the emitter (not embedded) fed with water at temperatures below 120 °C connected with a centralized heating supply source intended to be installed in buildings. The panels should be installed with an upper insulation. The European Standard does not apply to independent heating devices. The European Standard also defines the additional common data that the manufacturer has to provide to the trade in order to ensure the correct application of the products. This European standard does not cover the performance of hanging accessories. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indis-pensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

13 5 Requirements 5.1 General manufacturing requirements The thermal output of a pre-fabricated ceiling mounted radiant panel is mainly transferred downwards to the space by radiation. The thermal output upwards shall be minimized by insulation. The maximum surface temperature of the lateral edges shall not exceed the minimum surface temperature of the radiant sheet between the last two wet surfaces. For ceiling panels with a construction according to Figure 1 with a tube pitch of X (mm), the distance between the axis of the outside tubes and the edges has to have a minimum distance of 0,5X (mm). The panel is freely suspended above the useful space and designed to be a permanent part of the building although not a part incorporated in the building structure Air flow across the panel is to be prevented. 5.2 Surface protection If the material in use requires protection, measures for protection against corrosion should be provided. Paint and varnishes used for protection are considered as part of the free hanging heating surface and are, therefore subject to requirement to dangerous substance. When and where required the surface protection of the pre-fabricated ceiling mounted radiant panel shall be in accordance with EN ISO 2409 and its performance declared by the manufacturer by referring to class 0 or 1 given in EN ISO 2409.

5 Introduction This European Standard results from the recognition, that heated and chilled ceiling radiant panels falling into the field of application hereinafter stated are traded on the basis of their thermal output. For evaluating and comparing different heated and chilled ceiling surfaces it is therefore necessary to refer to a heating stipulated value. As installations with ceiling mounted radiant panels can also be used in practice for space cooling, it is nec-essary to have a test method for evaluating the cooling capacity. Installations with different free hanging heating and cooling surfaces need, for the use of space heating a test method for evaluating the heating out-put. The test method differs from the method for ceiling mounted radiant panels. The European Standard EN 14037, Free hanging heating and cooling surfaces for water with a temperature below 120°C, consists of the following parts: — Part 1: Pre-fabricated ceiling mounted radiant panels for space heating - Technical specifications and re-quirements; — Part 2: Pre-fabricated ceiling mounted radiant panels for space heating - Test method for thermal output; — Part 3: Pre-fabricated ceiling mounted radiant panels for space heating - Rating method and evaluation of radiant thermal output; — Part 4: Pre-fabricated ceiling mounted radiant panels for space heating - Test method for cooling capacity; — Part 5: Open or closed heated ceiling surfaces - Test method for thermal output. kSIST FprEN 14037-1:2015

6 1 Scope This European Standard defines technical specifications and requirements of free hanging prefabricated ceil-ing mounted radiant panels with an air gap between construction and the emitter (not embedded) fed with water at temperatures below 120 °C connected with a centralized heating supply source intended to be in-stalled in buildings. The panels should be installed with an upper insulation. The European Standard does not apply to independent heating devices. The European Standard also defines the additional common data that the manufacturer shall provide to the trade in order to ensure the correct application of the products. This European standard does not cover the performance of hanging accessories. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indis-pensable for its application.

13 5 Requirements 5.1 General manufacturing requirements The thermal output of a ceiling mounted radiant panel is mainly transferred downwards to the space by ra-diation. The thermal output upwards shall be minimized by insulation. The maximum surface temperature of the lateral edges shall not exceed the minimum surface temperature of the radiant sheet between the last two wet surfaces. For ceiling panels with a construction according to Figure 1 with a tube pitch of X (mm), the distance between the axis of the outside tubes and the edges has to have a minimum distance of 0,5X (mm). The panel is freely suspended above the useful space and designed to be a permanent part of the building although not a part incorporated in the building structure Air flow across the panel is to be prevented. 5.2 Surface protection If the material in use requires protection, measures for protection against corrosion should be provided. Paint and varnishes used for protection are considered as part of the free hanging heating surface and are, therefore subject to requirement to dangerous substance. When and where required the surface protection of the ceiling mounted radiant panel shall be in accordance with EN ISO 2409 and its performance declared by the manufacturer by referring to class 0 or 1 given in EN ISO 2409. kSIST FprEN 14037-1:2015

15 5.5.2 Vertical deflection of radiant ceiling panels The maximum vertical deflection between fixing points should be no more than the distance between the fixing points divided by 300 (thus the maximum vertical deflection would be 7 mm for a 2 m distance be-tween fixing points, 10 mm for 3 m between fixing points, etc.) NOTE These tolerances apply only to manufactured panels before installation, since site welding can cause distor-tion. 5.6 Resistance to fixings The fixing points on the ceiling mounted radiant panel shall be designed to withstand a load of 5 times the allocated mass of the panel, including water, without failure. A loading up to 3 times of the allocated filled mass shall be achieved without any occurrence of permanent deformation. The manufacturer shall submit a statement for the suitability and stability of the fixing points i
