22、tariat of which is held by ELOT. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2017, and conflicting national standards shall be withdrawn at the latest by July 2017. Attention is drawn to
23、the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12976-1:2006. This document has been prepared under a mandate given to CEN by th
24、e European Commission and the European Free Trade Association. Most significant changes in EN 12976-1:2017 and EN 12976-2:2017 since the 2006 editions of both parts: The first edition of the EN 12976 series was published in 2000. The standard series provided an important basis for the assessment of
25、the performance as well as the reliability and durability of Factory made solar thermal systems. In the past 15 years or so, several important technological developments and changes of the framework conditions, such as e.g. the aspect of requiring “Energy Labelling”, the EN 12976 series underwent se
26、veral important changes. The following modifications are the most important ones that have been implemented in this new edition of EN 12976-1: safety valves: new requirement that safety valves shall conform with EN 1489; resistance to external influences: consideration that the solar components can
27、impact on the performance and durability of essential building elements, e.g. roofs and facades; labelling: harmonisation with ErP; Annex C (new): definition of system families; possible range of variations within one system type. EN 12976, Thermal solar systems and components Factory made systems,
28、is currently composed with the following parts: Part 1: General requirements; Part 2: Test methods. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, C
29、yprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and

DIN EN 12976-1:2017-04 EN 12976-1:2017 (E) 5 Introduction Drinking water quality: In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by this standard: a) this standard provides no information as to whethe
31、r the product may be used without restriction in any of the Member States of the EU or EFTA; b) it should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force. Factory M
32、ade and Custom Built solar heating systems: The standards EN 12976-1, EN 12976-2, EN 12977-1, EN 12977-2, EN 12977-3, EN 12977-4 and EN 12977-5 distinguish two categories of solar heating systems: Factory Made solar heating systems and Custom Built solar heating systems. The classification of a syst
33、em as Factory Made or Custom Built is a choice of the final supplier, in accordance with the following definitions. Factory Made solar heating systems are batch products with one trade name, sold as complete and ready to install kits, with fixed configurations. Systems of this category are considere
34、d as a single product and assessed as a whole. If a Factory Made Solar Heating System is modified by changing its configuration or by changing one or more of its components, the modified system is considered as a new system for which a new test report is necessary. Requirements and test methods for
35、Factory Made solar heating systems are given in EN 12976-1 and EN 12976-2. Custom Built solar heating systems are either uniquely built, or assembled by choosing from an assortment of components. Systems of this category are regarded as a set of components. The components are separately tested and t
36、est results are integrated to an assessment of the whole system. Requirements for Custom Built solar heating systems are given in EN 12977-1; test methods are specified in EN 12977-2, EN 12977-3, EN 12977-4 and EN 12977-5. Custom Built solar heating systems are subdivided into two categories: Large
37、Custom Built systems are uniquely designed for a specific situation. In general HVAC engineers, manufacturers or other experts design them. Small Custom Built systems offered by a company are described in a so-called assortment file, in which all components and possible system configurations, market
38、ed by the company, are specified. Each possible combination of a system configuration with components from the assortment is considered as one Custom Built system. DIN EN 12976-1:2017-04 EN 12976-1:2017 (E) 6 Table 1 shows the division for different system types: Table 1 Division for factory made an
39、d custom built solar heating systems Factory Made Solar Heating Systems (EN 129761 and EN 129762) Custom Built Solar Heating Systems (EN 129771, EN 129772 and EN 129773) Integrated collector storage systems for domestic hot water preparation Forced-circulation systems for hot water preparation and/o
40、r space heating, assembled using components and configurations described in an assortment file (mostly small systems) Thermosiphon systems for domestic hot water preparation Forced-circulation systems as batch product with fixed configuration for domestic hot water preparation Uniquely designed and
41、assembled systems for hot water preparation and/or space heating (mostly large systems) NOTE Forced circulation systems can be classified either as Factory Made or as Custom Built, depending on the market approach chosen by the final supplier. Both Factory Made and Custom Built systems are performan
42、ce tested under the same set of reference conditions as specified in EN 129762:2017, Annex B, and in EN 129772:2012, Annex A. In practice, the installation conditions may differ from these reference conditions. A Factory Made system for domestic hot water preparation may have an option for space hea
43、ting, however this option should not be used or considered during testing as a Factory Made system. DIN EN 12976-1:2017-04 EN 12976-1:2017 (E) 7 1 Scope This European Standard specifies requirements on durability, reliability and safety for Factory Made solar heating systems. The standard also inclu
44、des provisions for evaluation of conformity to these requirements. Concept of system families is included, as well. The requirements in this standard apply to Factory Made solar systems as products. The installation of these systems including their integration with roofs or facades is not considered
45、, but requirements are given for the documentation for the installer and the user to be delivered with the system (see also 4.6). External auxiliary water heating devices that are placed in series with the Factory Made system are not considered to be part of the system. Cold water piping from the co
46、ld water grid to the system as well as piping from the system to an external auxiliary heater or to draw-off points is not considered to be part of the system. Piping between components of the Factory Made system is considered to be part of the system. Any integrated heat exchanger or piping for spa
47、ce heating option (see Introduction, last paragraph) is not considered to be part of the system. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
