PED Harmonized standards for unfired steam generators - EN 12 953 applicable?

[uttensio]

Do you use EN 12953 (intended for fired or electric boilers) as part of the conformity assessment process for higher-pressure unfired steam generators? (EN 13445 is not directly applicable due to 110C scope limitation).

Both EN 12953 and 12953 are considered harmonized standards;https://ec.europa.eu/docsroom/documents/64634/attachments/1/translations/en/renditions/native

If your device is unfired (do you maybe have some sort of sketch?) I'd be tempted to think this is more of an EN 12952 application, since 12953 is for fired equipment I think.

I thought that both 12953 and 12952 were for fired boilers - 12953 for firetube and electric, and 12952 for watertube?

I don't have a sketch handy, but for example picture a kettle reboiler with a high temp fluid as its heat source, making steam in the shell.

I think we’ve used 12952 previously for vessels that had electric insert heaters for steam generation.
