EN 13445 Maintenance Agency
Overview and organisation of the maintenance agency
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 2014/68/EU (so-called PED). Through the publication of its reference in the Official Journal of the European Union, it gives presumption of conformity to the essential safety requirements identified in the Annex ZA of each part.
EN 13445 is the key standard in the field of pressure equipment.

EN 13445 Maintenance agency acts under the responsibility of the technical committee CEN/TC 54. It is the central point for collecting questions that are addressed either during meetings or by correspondence. When the experts cannot resolve the questions by e-mail, they discuss 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 question leads to an action (interpretation, correction or modification) or not.
