This European Standard shall be given th

17、e status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2017, and conflicting national standards shall be withdrawn at the latest by June 2017. Attention is drawn to the possibility that some of the elements of this document may be the sub

18、ject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13618:2011. EN 13618:2016 includes the following significant technical changes with respect to EN 13618:2011: a) the stress corrosion testing is carried

19、out with ammonium only; b) requirement ad test method for resistance of seat of female fitting are deleted; c) in Table 8, specific minimum flow rates and minimum bore diameters are left open; d) for testing the pressure jumps resistance, detailed specification for DN and applied test pressure are g

20、iven; e) new test methods for corrosion resistance and UV resistance are introduced; f) in Table A.2, the dimensions C are reduced; g) in hydraulic performance and durability test, the number of impulses is reduced; h) the recommended surveillance testing of specific functional requirements is intro

21、duced.
