ISO 9459-2 has lost its relevance now with new

ISO 9459-2 will remain

ISO 9459-2 still part of Keymark?

Chance for adapt ErP tapping cycles???

Substitution of climate locations uncritical

Additional locations optional

Clear climate data sets desirable

Davos is also relevant for prEN 15316-4-3

Current tapping profiles unrealistic

Next Steps

If ISO 9459-2 should stay, a distinction

between solar only and solar +

Supplementary might be necessary

Solar only could stay as it was (mainly for

TSS, at the moment >90% of certificates)

Solar plus supplementary might be

harmonized with ErP

- Only ISO 9459-5 for EN 12976

- EN 12977-2 for EN 12977

Every ISO 9459-5 test result could be

used for solar only evaluation too

Two main categories for simple and for

more complex systems

A third one for DHW-heating useful

ISO 9459-2 might stay as it is

ISO 9459-5 need to be adapted to

faux>0.75

EN 12976 is nearly complete

EN 12977 might be completely revised or

partly substituted by other standards

Which are the most important steps for SKN and CEN TC 312?

17/ 18 October 2016 Solar Keymark Network Meeting Crete 5

Everything will be kept as it was

Only one drain at the end of each day

ISO 9459-2 and -5 able to be used

Product fiches for solar devices could easily be

included on additional pages of data sheet

(But only for ISO 9459-5 tested systems)

Clear distinction between ErP and SK boundary

conditions and climate data sets

No need for harmonisation to ISO 9459-2

Now open to multi tapping and heating!

ErP tapping profiles out of new EN 12976-

2_2016 could be used

ErP locations + optional ones possible

- Helsinki

- Strasbourg

- Athens

- Davos (optional)

One declared reference tapping profile for each

configuration

Limited number of simulations (important for

future EN 12977-2 or new standard simulations)

New design of data sheet necessary

Next steps

Conclusion

Harmonization is possible

Certification of solar only systems (solar devices; SD) could stay as it is

Distinction between solar only (SD) and solar plus supplementary (solar water heater;

SWH) necessary

Harmonized boundary conditions only for solar water heater (more complex systems)

Perfect starting point to restructure, improve and harmonize EN 12977-2

Harmonization of Solar Keymark & ErP
