What is BS EN 12976-2 about?
BS EN 12976-2 is the second part of the multi-series standard. BS EN 12976-2 includes thermal solar systems and their components that are factory-made.
BS EN 12976-2 specifies test methods for validating the requirements for factory-made thermal solar heating systems and includes two test methods for thermal performance characterization by means of whole system testing.
Who is BS EN 12976-2 for?
BS EN 12976-2 on factory-made thermal solar systems is for:
- Manufactures of solar photovoltaic panels and solar system components
- Suppliers of solar system components
- Test providers of the thermal solar system
Why should you use BS EN 12976-2?
BS EN 12976-2 on factory-made thermal solar systems enables the final supplier to classify and choose between a factory-made or a custom-built thermal solar system.
BS EN 12976-2 assists suppliers to modify a solar heating system by changing its configuration or by changing one or more of its components. Thus, the supplier can set up a modified system that is considered as a brand-new system just with the addition of a new test report.
BS EN 12976-2 helps the manufacturers, suppliers, and users validate the requirements and test methods for factory-made solar heating systems.
What’s changed since the last update?
BS EN 12976-2:2019 supersedes BS EN 12976-2:2017, which is withdrawn.
- Few editorial changes, more clarification with respect to testing requirements of reverse flow protection and mechanical load testing
- Confusion about different Qref values has been solved, there should only be one Qref value
- Main changes related to ErP and the new mechanical load test
- Annex ZA (new), ZB (new), ZC (new): harmonization with regulations (EC) No 811/2013, (EC) No 812/2013 and (EC) No 814/2013 respectively
