BIBLIOGRAFIA
La norma fornisce, in conformità alla legislazione vigente, i criteri principali di progettazione, costruzione e collaudo degli impianti di regolazione della pressione e misura del gas naturale, convenzionalmente denominati impianti REMI, allacciati alle reti di trasporto gas a valle del punto di consegna dal Trasportatore al Distributore/Cliente finale. La norma si applica alla realizzazione di impianti di ricezione e prima riduzione del gas naturale di nuova realizzazione e al rifacimento parziale o totale di quelli già esistenti. I requisiti della presente norma non si applicano alla progettazione e alla costruzione di installazioni ausiliarie, quali campionatori di gas, calorimetri e odorizzatori. Le suddette installazioni vengono trattate nelle relative norme nazionali o europee, se esistono, o in altre norme pertinenti. I requisiti della presente norma fanno riferimento ai dati fisici e chimici relativi ai gas combustibili della prima e della seconda famiglia, come definiti nella UNI EN 437.
