CEN/TC 228 - Impianti di riscaldamento - Progettazione, fabbisogni di energia e sicurezza (UNI/TS 11300-2 e 11300-4)

Data Documento: 12/10/2009
Organo Tecnico: CEN/TC 228 - Heating systems and water based cooling systems in buildings

Note:
in the course of the revision of EN 12828 in WG 1 an impasse was reached concerning the requirement whether each (as given in the current standard) or only at least one (as requested by the UK) heat generator needs to be equipped with a pressure limiter. WG 1 therefore asked TC 228 for guidance, which decided at its 21. plenary meeting of CEN/TC 228 on September 18th 2009 to put this question to the member countries.
