February  2016

voir la version française

The maintenance agency is intended to facilitate the use of the standard EN 13445 by providing, at European level, an accelerated process to give official answers to questions or modification requests regarding the application of this Standard.

Information about the updates and evolutions of the standard are also provided.

This information can be found and complemented at national level, from the standardization body responsible for this standard.

News
  • The last issue to edition 2015 of EN 13445 is available. To get this standard, contact your national standardization body. The English version is also available at AFNOR boutique

Overview

EN 13445 series of standards provides rules for the design, fabrication, and inspection of pressure vessels. It provides one means of conforming to essential safety requirements of the Pressure Equipment Directive 97/23/CE (so called PED). Through the publication of its reference in the Official Journal of European Union, it gives presumption of conformity to the essential safety requirements identified in Annex ZA of each Part.

EN 13445 is the key standard in the field of pressure vessels.

The third edition of EN 13445 "Unfired pressure vessels" was delivered in July 2014. The significant changes between the 2014 edition and the 2009 edition are detailed in the document Changes 2009-2014

EN 13445 is divided into parts which cover the following items:

  • General (EN 13445-1)
  • Materials (EN 13445-2)
  • Design (EN 13445-3)
  • Fabrication (EN 13445-4)
  • Inspection and testing (EN 13445-5)
  • Requirements for the design and fabrication of pressure vessels and pressure parts constructed from spheroidal graphite cast iron (EN 13445-6)
  • Additional requirements for pressure vessels of aluminum and aluminum alloys (EN 13445-8)
  • Additional requirements for pressure vessels of nickel and nickel alloys (EN 13445-10)

It is completed by four technical reports (informative documents):

  • Guidance on the use of conformity assessment procedures (CEN CR 13445-7)
  • Conformance of EN 13445 series to ISO 16528-1 (which deals with boilers and pressure vessels) (CEN/TR 13445-9)
  • Examples of application of EN 13445 to the design and the construction of an unfired pressure vessel, and to the design of a target vessel with saddle supports (CEN TR 13445-101 and -102)
Organisation of the maintenance agency
EN 13445 Maintenance agency acts under the responsibility of the technical committee CEN/TC 54. It is the midpoint for collecting questions. They are dealt with either during meetings or by correspondence. When the experts cannot resolve the questions by exchanging messages only, then these are discussed during the meetings of the maintenance agency for final validation. The answers to the questions are reviewed by the working groups of CEN/TC 54 and submitted to the maintenance agency experts for validation. The applicant is informed whatever the result is an action (interpretation, correction or modification) or not.

The process used to deal with questions and modification requests is shown on the following diagram:

The list of questions registered on EN 13445:2014 is available by downloading here.

The questions are given in a chronologic order for each Part (or sub-Part) ; for the questions still under discussion, no answer is shown.

Submission of questions

The downloadable form shall be used to submit questions; it shall be sent to the secretariat of EN 13445/MHD at the following e-mail address: en13445@unm.fr
