19、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of an identical text or by endorsement, at the latest by June 2001, and conflicting national standards shall be withdrawn at the latest by June 2001. According to the CEN/CENELEC Internal Reg
20、ulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the
21、 United Kingdom. Annex A is informative.

22、n, 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 adoption of verifiable European criteria, existing natio
23、nal 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 12976-1:2000 as well as EN 12976-2:2000 and the prestandards prENV 12977-1:2000 to prENV 12977-3:2000 distinguish two categories of sola
24、r 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 are batch products with one
25、 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 more of its components, the
26、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- 1:2000 and EN 12976-2:2000. Custom Built solar heating systems are either uniquely built, or assembled by choosing from
27、an assortment of components. Systems of this category are regarded as a set of components. The components are sepa- rately tested and test results are integrated to an assessment of the whole system. Requirements for Custom Built solar heating systems are given in prENV 12977-1:2000, test methods ar
28、e specified in prENV 12977- 2:2000 and prENV 12977-3:2000. 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 s
29、ystems offered 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 syst
30、em.

33、rced circulation systems can be classified either as Factory Made or as Custom Built, depending on the market approach chosen by the final supplier. 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
34、-2:2000 and annex A of prENV 12977-2:2000. In practice, the in- stallation 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, how- ever this option should not be used or considered during testin
35、g as a Factory Made system.

Th
36、e standard also includes provisions for evaluation of conformity to these require- ments. 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
37、and the user which is delivered with the system (see also the clause 3). 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are
38、listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). E

47、tem A packaged solar energy system for the purpose of hot water preparation only, either of the close-coupled or remote-store type. The system consists of either one integral component or of a uniform set and configuration of components. It is produced under conditions, which are presumed uniform, a
48、nd 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 name, configuration, components and dimensions (see also the In- troduction). NOTE 2 External auxiliary water hea
49、ting 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 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 con- sidered to be part o
