28、States of the EU or EFTA,2) while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force.b) Factory made and custom built solar heating systemsEN 129761, EN 129762, FprEN 129771, EN 129772, EN

29、 129773, EN 129774 and EN 129775 distinguish two categories of solar heating systems:1) factory made solar heating systems; and2) 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 defi

30、nitions.3) 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 considered as a single product and assessed as a whole.If a factory made solar heating system is modified by chang

31、ing its configuration or by changing one or more of its components, the modified system is considered as a new system. Requirements and test methods for factory made solar heating systems are given in EN 129761 and EN 129762.4) Custom built solar heating systems are either uniquely built or assemble

32、d by 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 EN 129771, test me

33、thods are specified in EN 12977-1, EN 12977-2, EN 12977-3, EN 12977-4 and EN 12977-5. Custom built solar heating systems are subdivided into two categories:i) large custom built systems are uniquely designed for a specific situation. In general, they are designed by HVAC engineers, manufacturers or

34、other experts;ii) small custom built systems 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

35、is considered as one custom built system.Table 1 shows the division for different system types.Table 1 Division for factory made and custom built solar heating systemsFactory made solar heating systems ( EN 12976-1 and EN 12976-2 )Custom built solar heating systems ( EN 12977-1 , EN 12977-2 , EN 129

39、 by the final supplier.NOTE 2 Both factory made and custom built systems for domestic hot water preparation are performance tested under the same set of basic reference conditions as specified in EN 12976-2:2017, Annex B and in EN 129772:2018, Annex A. In practice, the installation conditions may di

40、ffer from these reference conditions.NOTE 3 Solar heating systems for both heating and cooling can so far not be performance tested; if the cooling option is not considered, then the solar heating system can be performance tested as a space heating system.6BS EN 129771:2018EN 12977-1:2018 (E)1 Scope
