A guideline to the EN 12975 allowing uniform interpretation of requirements, harmonized application of the standard and presentation of results |
||
|
A guide directed to established and new test laboratories for collector testing. The main purpose is to give a quick introduction to the standard for new laboratories and in general to contribute to a uniform interpretation of the standard and presentation of results. |
Test laboratories |
|
|
A guide directed to manufacturers and importers of collectors. The purpose is to give a very light introduction to the standard and to explain how it is used for type testing as well as for innovation and development support. |

|
A procedure for calculation of energy output of solar thermal collectors |
||
|
Software developed to calculate the annual energy output from a solar thermal collector. The software is free of charge and can be downloaded from the Technical Research Institute of Sweden’s (SP) or the QAiST's webpages. |
