European foreword
This document (EN 13445-3:2014/A2:2016) has been prepared by Technical Committee CEN/TC 54
“Unfired pressure vessels”, the secretariat of which is held by BSI.
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 February 2017, and conflicting national standards
shall be withdrawn at the latest by February 2017.

1 Modification to Annex M (informative), In service monitoring of vessels
operating in fatigue or creep service
Replace the existing Annex M with the following:
“
Annex M
(informative)
In service monitoring of vessels operating in fatigue or creep service
M.1 Purpose
This annex gives guidance on the monitoring of vessels which operate in either fatigue or creep service.
M.2 Fatigue operation
The operator should record in a suitable fashion the number of load cycles occurring and a plan should
be prepared for the inspection of the vessel throughout its life. Typically, a pressure vessel operating in
fatigue should be internally and if necessary externally inspected (by VT, RT, UT, PT, etc. as relevant).
Surface inspection is generally more relevant than volumetric inspection.
The first inspection should take place after a period corresponding to not more than 50 % of the
calculated allowable fatigue life. The following inspections should take place after a further period of
not more than 50 % (i.e. before 100 % of the calculated allowable fatigue life).
