    Abstract - (Show below) - (Hide below)

    La norma fornisce raccomandazioni e specifica i requisiti per la progettazione di impianti all'interno di edifici per il convogliamento di acque destinate al consumo umano, e di tubazioni all'esterno di edifici ma all'interno delle proprietà. La norma si applica a impianti di nuova costruzione, a modifiche e riparazioni di impianti già esistenti.
