General Information
- Abstract
This Part of this European Standard defines the terms, definitions, symbols and units that are used throughout the EN 13445.
This Part of EN 13445 also gives guidelines on the principles on which each part of the standard has been based. This information is aimed to aid the user of the EN 13445. This European Standard applies to unfired pressure vessels subject to a maximum allowable pressure greater than 0,5 bar gauge but may be used for vessels operating at lower pressures, including vacuum.
This European Standard applies to maximum allowable temperatures for which creep effects need not be considered, i.e. for maximum allowable temperatures for which the corresponding maximum calculation temperature renders a relevant proof strength smaller than the 100 000 h creep rupture strength. For ferritic steels the temperature limit corresponds to calculation temperatures below approximately 380 °C
In EN13445-3:2002 two methods of Design by Analysis (DBA) are given in Annex B and Annex C respectively. Both of these are normative. However Parts 2, 4 and 5 of this edition of the standard do not include provision within their respective areas of responsibility for vessels designed using Design by Analysis - Direct Route (DBA) of Annex B of EN13445-3
NOTE The selection, application and installation of safety related accessories intended to protect pressure vessels during operation are covered in prEN 764-7.

to direct generated heat or flame impingement from a firedprocess. This does not exclude vessels subject to electrical heating or heated process streams.In Parts 1 to 5 only pressure vessels manufactured from steels and steel castings as detailed in Part 2 of thisstandard are covered. Part 6 specifically deals with spheroidal graphite cast iron and special considerations apply.Part 1This Part outlines the basic principles underpinning the standard.
The manufacturer is required to declare that thetechnical design specification and the supporting documentation are in compliance with the requirements of thisstandard.Unforeseen factors may arise that require design modifications and/or manufacturing concessions. These need tobe handled with the same rigour as the original design.Part 2This Part deals with the general philosophy on materials, material grouping and low temperature behaviour inrelation to Room Temperature performance. It is limited to steel with sufficient ductility and excludes at presentmaterials operating in the creep range. Part 2 provides the general requirements for establishing technical deliveryconditions.Furthermore Part 2 includes the requirements for marking. Four annexes give further details. The normativeAnnex A includes the material grouping system, which is in accordance with CR ISO 15608:2000. This system isused throughout the whole standard. Furthermore Annex A adds a list of all those material grades based uponEuropean base material standards which are accepted to be used for unfired pressure vessels made to thisstandard The normative Annex B gives the necessary information on the requirements for the prevention of brittlefracture in the base material and the welds. Two methods based upon a code of practice developed from fracturemechanics are covered. The informative Annex C gives information on technical delivery conditions for cladproducts. Annex D gives an informative survey on European base material and component standards and theirsystematic nomenclature.Part 3This Part of this standard gives the rules to be used for design and calculation under internal and/or externalpressure (as applicable) of pressure bearing components of Pressure Vessels, such as shells of various shapes,flat walls, flanges, heat exchanger tubesheets, including the calculation of reinforcement of openings. Rules arealso given for components subject to local loads and to actions other than pressure.
