This document is currently submitted to the CEN Enquiry. This document will supersede EN 13617-3:2012. Compared with the 2012 edition, the following fundamental changes were made: — Shear valves for aqueous urea solution added. — Testing for vapour shear valves further differentiated from testing for fuel shear valves. Tests B.15 and B.16 are introduced. — Fire resistance test B.14 and pass/fail criteria defined in Table 3 This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This European Standard Petrol filling stations consists of four parts: — Part 1: Safety requirements for construction and performance of metering pumps, dispensers and remote pumping units; — Part 2: Safety requirements for construction and performance of safe breaks for use on metering pumps and dispensers; — Part 3: Safety requirements for construction and performance of shear valves; — Part 4: Safety requirements for construction and performance of swivels for use on metering pumps and dispensers. oSIST prEN 13617-3:2018
