European foreword
This document (EN 12976-1:2021) has been prepared by Technical Committee CEN/TC 312 “Thermal
solar systems and components”, the secretariat of which is 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 2022, and conflicting national standards shall be
withdrawn at the latest by June 2022.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 12976-1:2017.
The first edition of the EN 12976 series was published in 2000. The standard series provided an
important basis for the assessment of the performance as well as the reliability and durability of
Factory made solar thermal systems. In the past 15 years or so, several important technological
developments and changes of the framework conditions, such as e.g. the aspect of requiring “Energy
Labelling”, the EN 12976 series underwent several important changes.
The following modifications are the most important ones that have been implemented in this new
edition of EN 12976-1:
— Electrical safety: If the system contains any electrical devices, these shall conform to EN 60335-1
and EN 60335-2 (relevant parts) thus providing the scope due to different sub standards for pumps
(EN 60335-2-41 / EN 60335-2-51), heat pumps (EN 60335-2-40, maybe relevant for the future)
and maybe other devices in the future.
— safety valves: new requirement that safety valves shall conform with EN 1489;
— resistance to external influences: consideration that the solar components can impact on the
performance and durability of essential building elements, e.g. roofs and facades;
— labelling: harmonization with Energy-Related Products Directive (ErP Directive 2009/125/EC);
— Annex C (new): definition of system families; possible range of variations within one system type.
EN 12976, Thermal solar systems and components — Factory made systems, is currently composed with
the following parts:
— Part 1: General requirements;
— Part 2: Test methods.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
