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). This consolidated version consists of the second edition (2008) and its amendment 1 (2015). Therefore, no need to order amendment in addition to this publication.
