DIN EN 12975-1:2011-01 EN 12975-1:2006+A1:2010 (E) 4 Introduction In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by this standard, it is

21、pointed out that: 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 national regulations concerning the us

22、e and/or the characteristics of this product remain in force. DIN EN 12975-1:2011-01 EN 12975-1:2006+A1:2010 (E) 5 1 Scope This European Standard specifies requirements on durability (including mechanical strength), reliability and safety for liquid heating solar collectors. It also includes provisi

23、ons for evaluation of conformity to these requirements. It is not applicable to those collectors in which the thermal storage unit is an integral part of the collector to such an extent, that the collection process cannot be separated from the storage process for the purpose of making measurements o

24、f these two processes. !It is basically applicable to concentrating collectors; thermal performance testing as given in EN 12975-2:2006, 6.3. (quasi dynamic testing) is also applicable to most concentrating collector designs, from stationary non-imaging concentrators as CPCs to high concentrating tr

25、acking designs.“ Collectors that are custom-built (built in, roof integrated collectors that do not comprise factory made modules and are assembled directly on the place of installation) cannot be tested in their actual form for durability, reliability and thermal performance according to this stand

26、ard. Instead, a module with the same structure as the ready collector is tested. The module gross area in the case of custom built collectors should be at least 2 m2. The test is valid only for larger collectors, than the tested module. For collectors the national and European Guidelines for Structu

27、ral Planning and overhead glazing are not valid. Therefore this standard should be applied for the design of the static of the collector. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

34、ee 5.11 of EN 12975-2:2006). The optional test for impact resistance (see 5.10 of EN 12975-2:2006) shall be carried out if requested. The result shall be recorded. NOTE Regarding the durability and reliability of elastic materials it is recommended to refer to ISO 9808 and ISO 9553. 5.3 Pass criteri

35、a 5.3.1 General The pass criteria for the reliability tests are given for each test in 5.3.2 to 5.3.10. The term “no major failure“, denotes that none of the following occurs: - Absorber leakage or such deformation that permanent contact between absorber and cover is established; - Breaking or perma

36、nent deformation of cover or cover fixing; - Breaking or permanent deformation of collector fixing points or collector box; - Vacuum loss, such that vacuum or subatmospheric collectors shall be classified according to the definition in EN ISO 9488 (only applicable for vacuum and subatmospheric colle

37、ctors); - Accumulation of humidity in form of condensate on the inside of the transparent cover of the collector exceeding 10 % of the aperture area. DIN EN 12975-1:2011-01 EN 12975-1:2006+A1:2010 (E) 7 NOTE The evaluation of accumulation of humidity for application of the pass criteria should be ap

38、plied only on the following tests : - external Thermal Shock - Rain Penetration Test 5.3.2 Internal pressure for absorber The test pressure shall be as specified in 5.2 of EN 12975-2:2006. In the case of absorbers made of organic materials, climate conditions according to Table 2 of EN 12975-2:2006

After the internal pressure test, the collector shall not show any major failure as defined in 5.3.1. 5.3.3 High temperature resistance When tested in accordance with 5.3 of EN 12975-2:2006, the collector shall not show any major failure as defined in 5.3.1. 5.3.4 Exposure When tes

40、ted in accordance with 5.4 of EN 12975-2:2006, the collector shall not show any major failure according to 5.3.1 and none of each potential problems of their components shall be graded 2 on the scale given in B.5.5 of EN 12975-2:2006. 5.3.5 External thermal shock When tested in accordance with 5.5 o

41、f EN 12975-2:2006, the collector shall not show any major failure as defined in 5.3.1. 5.3.6 Internal thermal shock When tested in accordance with 5.6 of EN 12975-2:2006, the collector shall not show any major failure as defined in 5.3.1. 5.3.7 Rain penetration NOTE This test is applicable only for

47、er three freeze-thaw cycles. 5.4 Procedure The required number of collectors shall be available for testing. The collectors shall be tested in accordance with 5.2. The collectors conform to this standard, only if all pass criteria are fulfilled. Freeze resistance shall be tested, for collectors whic

48、h the manufacturer claims can withstand freezing and freeze/thaw cycling and which are not intended to be filled with antifreeze fluids. 6 Safety The maximum fluid temperature to be considered in the design of a solar collector or solar plant is the collector stagnation temperature. Materials to be

49、used in the manufacture of collectors or installations incorporating the collector (expansion tanks, safety valves, etc.) shall be chosen taking into account this temperature. The stagnation temperature shall be calculated in accordance with Equation C.1 of EN 12975-2:2006 under the following climate parameters: - Hemispherical irradiance on collector plane 1000 W/m; - Surrounding air temperature 30 C. Stagnation temperature (see Annex C of EN 12975-2:2006) may be combined with the high temperature resistance or exposure test. The collector shall provide f
