This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2012, and conflicting national standards shall be withdrawn at the latest by December 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. 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 EN 13480 for metallic industrial piping consists of eight interdependent and not dissociable Parts which are: Part 1: General; Part 2: Materials; Part 3: Design and calculation; Part 4: Fabrication and installation; Part 5: Inspection and testing; Part 6: Additional requirements for buried piping; CEN/TR 13480-7, Guidance on the use of conformity assessment procedures; Part 8: Additional requirements for aluminium and aluminium alloy piping. Although these Parts may be obtained separately, it should be recognised that the Parts are interdependent. As such the manufacture of metallic industrial piping requires the application of all the relevant Parts in order for the requirements of the Standard to be satisfactorily fulfilled. This European Standard will be maintained by a Maintenance MHD working group whose scope of working is limited to corrections and interpretations related to EN 13480.
The contact to submit queries can be found at http://portailgroupe.afnor.fr/public_espacenormalisation/CENTC267WG8/index.htm. A form for submitting questions can be downloaded from the link to the MHD website. After subject experts have agreed an answer, the answer will be communicated to the questioner. Corrected pages will be given specific issue number and issued by CEN according to CEN Rules. Interpretation sheets will be posted on the website of the MHD.

EN 13480-4:2012 (E) Issue 1 (2012-06) 8 5.2 Requirements on fabricators and installers of piping and supports 5.2.1 The fabricators and/or installers shall ensure the correct transport, handling, storage, fabrication and installation of all piping components including supports. 5.2.2 The fabricators and installers shall have access to facilities which enable them to handle the piping components including supports correctly and to carry out the required tests. 5.2.3 The fabricators and/or installers shall employ their own responsible supervisors and competent personnel. If sub-contractors are employed, the fabricator and/or installer shall remain responsible for their competence and the compliance with this European Standard. 5.2.4 All stages of fabrication and installation shall be supervised in such a way as to maintain the design integrity of the finished system. 5.2.5 Co-ordination between those responsible for design and those responsible for fabrication and/or installation shall be maintained at all times, to ensure that fabrication and installation is carried out in accordance with the design specification. 5.3 Requirements for fabrication and installation 5.3.1 Prior to any operation, a check shall be made to ensure that the spools and components supplied are in accordance with the relevant documents (specifications, drawings, certificates etc.). 5.3.2 Prefabricated spools and components shall be protected during handling, transport, and storage.
5.3.3 When joining spools or components, they shall not be strained nor deformed other than as may be required by the design. Designer's installation instructions, if any, shall be observed. NOTE 5.3.3 is deemed to be fulfilled, when the quality characteristics of the material are not impaired by cold or hot forming, e.g. by cutting, grinding, straightening or bending, of the pipes and when the different pipes have been joined such that stresses and deformations which can impair the safety of the piping are excluded. 5.3.4 Any temporary supports or restraints used as an aid during transport, installation or testing shall be removed prior to commissioning. 5.3.5 Appropriate measures shall be taken to avoid corrosion-inducing contamination of stainless steel and non-ferrous materials. If contamination occurs, it shall be properly removed as soon as practicable, notwithstanding any final treatment. NOTE Recommended methods for the prevention and removal of contamination on stainless steel are given in Annex A. 5.3.6 Piping for fluids which are likely to cause condensation shall be installed with adequate slopes and traps. 5.4 Classification of piping The piping systems shall be classified into different categories depending on the fluid carried, diameter and pressure. These are given in EN 13480-1:2012.

EN 13480-4:2012 (E) Issue 1 (2012-06) 9 5.5 Material grouping Material grouping shall comply with CEN ISO/TR 15608:2005. 5.6 Tolerances Tolerances shall comply with EN ISO 13920:1996, class C and class G except where other classes are specified in this European Standard. Angular tolerances for fabricated pipework shall be determined by the dimensional tolerance for the terminal points of the finished part. Alternative tolerances for fabrication and installation of pipework shall be determined and in all cases these shall be identified in the specification. Dimensional tolerances for fabricated spools shall comply with Annex B. 6 Cutting and bevelling 6.1 General Cutting and bevelling by machining shall be permitted for all materials. Flame cutting shall be permitted for material groups 1, 2, 3, 4 and 5 only with preheating as for welding.
NOTE Flame cutting for material groups 1 and 2 can be used for bevelling, if the required bevel forms and tolerances can be achieved and the heat affected zone has no detrimental effects on the quality of the weld.
For material groups 3, 4 and 5, the heat affected zone shall be removed by machining or grinding. Plasma cutting shall be permitted for all material groups given in this European Standard. Plasma cutting shall be preceded by preheating, as specified for welding in 9.11.1. Other cutting and bevelling processes shall be permitted, provided their suitability is demonstrated. 6.2 Transfer of marking for pressure parts For pressure parts, identification of materials shall remain possible, either by retaining or by transferring the mark stipulated by the product standard, or by using a unique code kept in the records of the piping fabricator. Stamping shall not introduce a notching effect, therefore stamping with round edges is recommended. If any method of marking other than hard-stamping or engraving (vibrograph) is used, the fabricator shall ensure that confusion between different materials is not possible, e.g. by separate handling (time and/or place), stamped bands. 7 Bending and other forming 7.1 General 7.1.1 Fabricators of f
