Popis
IEC 61770:2008
IEC 61770:2008 provides requirements for appliances for household and similar purposes to prevent the backsiphonage of non-potable water into the water mains. It also specifies requirements for hose-sets used for connecting such appliances to the water mains that supply water at a pressure not exceeding 1 MPa. The major changes in this edition as compared with the first edition are as follows: normative references are updated; some notes have been converted to normative text (3.10, 5.2, 6.3, 7.2 and Annex A); the type of petroleum spirit has been specified (9.3).
