11、006 (E) 2 Foreword This document (EN 1333:2006) has been prepared by Technical Committee CEN/TC 74 “Flanges and their joints”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsemen

12、t, at the latest by September 2006, and conflicting national standards shall be with-drawn at the latest by September 2006. This document supersedes EN 1333:1996. This document is based on the international standard ISO 7268:1983, but the misleading definition of “nominal pressure“ has been omitted

13、as it is so loosely related to the maximum allowable pressure. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Den-mark, Estonia, Finland, Franc

14、e, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxem-bourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzer-land and United Kingdom. EN 1333:2006 (E) 3 1 Scope This European Standard gives the definition of PN when applied t

15、o components of a pipework system, as specified in those standards which use the PN designation system. This standard specifies the PN numbers which are used. 2 Terms and definitions For the purposes of this document, the following term and definition applies. 2.1 PN alphanumeric designation used fo

16、r reference purposes related to a combination of mechanical and dimen-sional characteristics of a component of a pipework system. It comprises the letters PN followed by a dimensionless number. NOTE 1 The number following the letters PN does not represent a measurable value and should not be used fo

17、r calcu-lation purposes except where specified in the relevant standard. NOTE 2 The designation PN is not meaningful unless it is related to the relevant component standard number. NOTE 3 The maximum allowable pressure of a pipework component depends on the PN number, the material and design of the

18、component, its maximum allowable temperature, etc. The relevant European Component standards include tables of specified pressure/temperature ratings or, in minimum, include rules how to determine pressure/temperature ratings. NOTE 4 It is intended that all components with the same PN and DN designations have the same mating dimensions for compatible flange types. 3 Selection of PN The PN values shall be selected from: PN 2,5 PN 25 PN 160 PN 6 PN 40 PN 250 PN 10 PN 63 PN 320 PN 16 PN 100 PN 400
