This European Standard sha
19、ll be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2006, and conflicting national standards shall be withdrawn at the latest by July 2006. This European Standard supersedes EN 12976-1:2000. According to the CEN/CENELEC I
20、nternal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Ne

22、he quality of water intended for human consumption, caused by the product covered by this standard: a) This standard provides no information as to whether 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 adoptio
23、n of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force. Factory Made and Custom Built solar heating systems The standards EN 12976-1 as well as EN 12976-2 and the prestandards ENV 12977-1 to ENV 12977-3 distingui
24、sh two categories of solar heating systems: Factory Made solar heating systems and Custom Built solar heating systems. The classification of a system as Factory Made or Custom Built is a choice of the final supplier, in accordance with the following definitions. Factory Made solar heating systems ar
25、e batch products with one trade name, sold as complete and ready to install kits, with fixed configurations. Systems of this category are considered 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 mor
26、e 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 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
27、choosing from an assortment of components. Systems of this category are regarded as a set of components. The components are separately tested and test results are integrated to an assessment of the whole system. Requirements for Custom Built solar heating systems are given in ENV 12977-1; test metho
28、ds are specified in ENV 12977-2 and ENV 12977-3. Custom Built solar heating systems are subdivided into two categories: - Large Custom Built systems are uniquely designed for a specific situation. In general HVAC engineers, manufacturers or other experts design them. - Small Custom Built systems off
29、ered by a company are described in a so-called assortment file, in which all components and possible system configurations, marketed by the company, are specified. Each possible combination of a system configuration with components from the assortment is considered as one Custom Built system. Licens

NOTE 2 Both Factory Made and Custom Built systems are performance tested under the same set of reference conditions as specified in Annex B of EN 12976-2:2006 and Annex A of ENV 12977-
34、2:2001. In practice, the installation conditions may differ from these reference conditions. NOTE 3 A Factory Made system for domestic hot water preparation may have an option for space heating, however this option should not be used or considered during testing as a Factory Made system.

The standard also includes provisions for evaluation of conformi
36、ty to these requirements. The requirements in this standard apply to Factory Made solar systems as products. The installation of these systems itself is not considered, but requirements are given for the documentation for the installer and the user which is delivered with the system (see also 4.6).

The system consists of either one integral component or of
46、 a uniform set and configuration of components. It is produced under conditions, which are presumed uniform, and offered for sale under the same trade name. NOTE 1 A single system can be tested as a whole in a test laboratory, leading to representative results for all systems with the same trade nam
47、e, configuration, components and dimensions (see also the Introduction). NOTE 2 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 cold water grid to the system as well as piping from
48、 the system to an external auxiliary heater or to tapping 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 space heating option (see Introduction, NOTE 3) is not
49、 considered to be part of the system. 4 Requirements 4.1 General The system shall fulfil general safety requirements, e.g. care shall be taken to avoid protruding sharp edges on the outside of the system. 4.1.1 Suitability for drinking water The system shall conform to EN 806-1 (see also Introduction). 4.1.2 Water contamination The system has to be designed to avoid water contamination for backflow from all circuits to drinking main supplies.
