SIST EN 14037-1:2017

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. SIST EN 14037-1:2017

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.

Lact = Lsh
(only for this example) Figure 1 — Example for a typical ceiling mounted radiant panel 5.3 Materials The manufacturers shall declare the materials used for producing the pre-fabricated ceiling mounted radiant panels 5.4 Surface emissivity The radiating surface of the active heating surface should have an emissivity not lower than 0,8. 5.5 Mechanical resistance 5.5.1 Horizontal curvature of radiant ceiling panels Horizontal curvature should be no more than 10 mm for a 6 m panel when cold. Shorter ceiling panels should have a maximum curvature in proportion. SIST EN 14037-1:2017

15 NOTE These tolerances apply only to manufactured panels before installation, since site welding can cause distor-tion. 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 pre-fabricated 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 al-located 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 in accordance with pass/fail-criteria. 5.7 Pressure tightness The headers and their connections to the tubes of the active length (wet surface) of all products leaving the factory shall be tested for leaks with a test pressure equal to at least 1,3 times the maximum operating pres-sure stated by the manufacturer and declared in accordance with pass/fail-criteria. The test has to be carried out by using air as pressurizing fluid and be realized by means of a water tank or by leakage indicating mediums and a pneumatic circuit that provides the pressurized air. 5.8 Resistance to pressure A sample of a panel in accordance with EN 14037-2 shall be tested to ensure that no leakage or permanent deformation will occur at the maximum test pressure, which is a factor of 1,69 times the maximum operating pressure stated by the manufacturer and declared in accordance with pass/fail-criteria. 5.9 Dimensional tolerances The dimensional deviations of parts of the panel having an influence on the thermal output shall not be greater than the tolerances indicated in the manufacturer's drawings supplied to the laboratory with the testing samples. Under no circumstances shall they be greater than those stated in Table 2. The adherence of the dimensional tolerances of the test samples shall be verified by the test laboratory before the test of the thermal output. Table 2 — Dimensional tolerances Dimension Tolerances Outside diameter of tubes ±0,50 mm Distance between tubes ±2 % of the distance Length of tubes ±3,00 mm Length of radiant sheet ±3,00 mm Width of ceiling mounted radiant panel ±6,00 mm Thickness of sheet ±0,08 mm Height of lateral edges ±3,00 mm SIST EN 14037-1:2017

16 5.10 Upper Insulation The upper side of the ceiling mounted heating radiant panels shall be provided with insulation. The thermal resistance of the insulation has a substantial influence on the thermal output upwards. Ceiling panels used only for cooling can be realized without upper insulation. For the insulation of the pre-fabricated ceiling mounted radiant panel used by the manufacturer the follow-ing information shall be given: — thermal resistance in m2 K/W and specific mass in kg/m3 at 20 °C; — material for the top cover of the insulation; — reaction to fire of the materials. 5.11 Water flow resistance The manufacturer shall provide documentation containing the pressure losses under different mass flow conditions to calculate water flow resistance for differing types of connections and internal circulations. 5.12 Release of dangerous substances National regulations on dangerous substances may require, verification and declaration on release, and sometimes content, of dangerous substances, when construction products covered by this standard are placed on those markets. In the absence of European harmonized test methods, verification and declaration on release/content should be done taking into account national provisions in the place of use. NOTE An informative database covering European and national provisions on dangerous substances is available at the Construction website on EUROPA accessed through: http://ec.europa.eu/enterprise/construction/cpd-ds/ 5.13 Reaction to fire 5.13.1 General Where use of a pre-fabricated ceiling mounted radiant panels is subject to national regulatory requirements on reaction to fire, its reaction to fire performance shall be considered as the one of its components (i.e. ma-terial approach) and shall be declared as one of the following classes, according to EN 13501-1: a) Class A1, without the need for testing (CWT), when meeting the requirements, specified in 5.13.2, or otherwise, or b) class, defined according to the results of testing of the material(s) used in the unit, according to the standard(s) referred to in EN 13501-1, as specified in 5.13.3. Conversely, where use of such a unit is not subject to national regulatory requirements on reaction to fire, either class, determined according to a) or b) or “No Performance Determined” (NPD) may be declared. 5.13.2 Pre-fabricated ceiling mounted radiant panels classified as Class A1 without the need for testing The reaction to fire performance of pre-fabricated ceiling mounted radiant panels shall be declared as Class A11 without the need for testing, provided that the pre-fabricated ceiling mounted radiant panels are non-coated metallic material or coated metallic material where the coating does not exceed 1,0 mm of thickness

17 and 1,0 kg/m2 of mass per unit area2 and where relevant the insulation material is of class A1 without test-ing. 5.13.3 Pre-fabricated ceiling mounted radiant panels classified according to the test results For the purpose of the reaction to fire performance of the pre-fabricated ceiling mounted radiant panels each of its constituent materials including the insulating material if relevant, shall be classified according to EN 13501-1 and only the lowest class of such materials shall be declared. The class of an individual constitu-ent material shall be obtained as the result of the test method(s), relevant to this class, and as specified in the standards referred to in EN 13501-1. Test specimens used for the test methods, applicable for this classification, shall be prepared according to EN 13501-1 and to the relevant standards referred therein. Only one model is to be tested to assess the reaction to fire of a type. 5.14 Rated thermal output and characteristic equation The rated thermal output as defined in 3.35 and the thermal output under different operating conditions have to be determined according to EN 14037-3:2016. The value of the rated thermal output has to be given in W/m as well as K and n of the characteristic equation
= K „ tn [in W/m] as defined in EN 14037-2:2016, 8.12. 5.15 Surface temperature The maximum surface temperature is assumed equal to the system design inlet water temperature3. 6 Assessment and verification of constancy of performance - AVCP 6.1 General The compliance of pre-fabricated ceiling mounted radiant panels with the requirements of this standard and with the performances declared by the manufacturer in the Declaration of Performance (DoP) shall be demonstrated by: - determination of the product-type on the basis of type testing - factory production control by the manufacturer, including product assessment. The manufacturer shall always retain the overall control and shall have the necessary means to take respon-sibility for the conformity of the product with its declared performance(s). 6.2 Type testing 6.2.1 General All performances related to characteristics included in this standard shall be determined when the manufac-turer intends to declare the respective performances unless the standard gives provisions for declaring them without performing tests. (e.g. use of previously existing data, classification without further testing –CWFT- and conventionally accepted performance).
See Decision 2000/147 EC for non-substantial components. (add the reference to the Official Journal) 3
Pre-fabricated ceiling mounted radiant panels are heat emitters without internal heat source. The maximum water temperature is decided by the system designer and controlled by safety devices in the heating system. SIST EN 14037-1:2017

18 Assessment previously performed in accordance with the provisions of this standard, may be taken into ac-count provided that they were made to the same or a more rigorous test method, under the same AVCP sys-tem on the same product such that the results are applicable to the product in question. For the purposes of assessment, the manufacturer's products may be grouped into families, where it is con-sidered that the results for one or more characteristics from any one product within the family are repre-sentative for that same characteristics for all products within that same family In addition, the determination of the product type shall be performed for all characteristics included in the standard for which the manufacturer declares the performance: — at the beginning of the production of a new or modified pre-fabricated ceiling mounted radiant panels (unless it is a member of the same product range); or — at the beginning of a new or modified method of production (where this may affect the stated proper-ties); or — they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the free hang-ing ceiling mounted radiant panels design, in the raw material, in the supplier of the components (acces-sories) or in the method of production (subject to the definition of a family), which would affect signifi-cantly one or more of the characteristics. Where components are used whose characteristics have already been determined, by the component manu-facturer, on the basis of assessment methods of other product standards, these characteristics need not be re-assessed. The specifications of these components shall be documented. Products bearing regulatory marking in accordance with appropriate harmonized European specifications may be presumed to have the performances declared in the Declaration of Performance (DoP), although this does not replace the responsibility on the pre-fabricated ceiling mounted radiant panels manufacturer to ensure that the pre-fabricated ceiling mounted radiant panels as a whole are correctly manufactured and their component products (accessories) have the declared performance values. 6.2.2 Test samples, testing and compliance criteria The number of samples of pre-fabricated ceiling mounted radiant panels to be tested/assessed shall be in accordance with Table 3.

The maximum water temperature is decided by the system designer and controlled by safety devices in the heating system. 6.2.3 Test reports The results of the determination of the product type shall be documented in test reports. All test reports shall be retained by the manufacturer for at least 10 years after the last date of production of the pre-fabricated ceiling mounted radiant panels to which they relate. 6.2.4 Shared other party results A manufacturer may use the results of the product type determination obtained by someone else (e.g. by an-other manufacturer, as a common service to manufacturers, or by a product developer), to justify his own declaration of performance regarding a product that is manufactured according to the same design (e.g. di-mensions) and with raw materials, constituents and manufacturing methods of the same kind, provided that: –
the results are known to be valid for products with the same essential characteristics relevant for the product performance; SIST EN 14037-1:2017

20 –
in addition to any information essential for confirming that the product has such same performances related to specific essential characteristics, the other party who has carried out the determination of the product type concerned or has had it carried out, has expressly accepted4 to transmit to the manufac-turer the results and the test report to be used for the latter’s product type determination, as well as in-formation regarding production facilities and the production control process that can be taken into ac-count for FPC; –
the manufacturer using other party results accepts to remain responsible for the product having the de-clared performances and he also: –
ensures that the product has the same characteristics relevant for performance as the one that has been subjected to the determination of the product type, and that there are no significant dif-ferences with regard to production facilities and the production control process compared to that used for the product that was subjected to the determination of the product type; and –
keeps available a copy of the determination of the product type report that also contains the infor-mation needed for verifying that the product is manufactured according to the same design and with raw materials, constituents and manufacturing methods of the same kind. 6.3 Factory production control (FPC) 6.3.1 General The manufacturer shall establish, document and maintain an FPC system to ensure that the products placed on the market comply with the declared performance of the essential characteristics. The FPC system shall consist of procedures, regular inspections and tests and/or assessments and the use of the results to control raw and other incoming materials or components, equipment, the production process and the product. All the elements, requirements and provisions adopted by the manufacturer shall be documented in a sys-tematic manner in the form of written policies and procedures. This factory production control system documentation s
