A RE-EVALUATION OF THE ECCC GUIDANCE FOR THE ASSESSMENT OF FULL SIZE CREEP RUPTURE DATASETS
The European Creep Collaborative Committee’s “Guidance for the Assessment of Full Size
Creep Rupture Datasets” was first published in 1996. Over the last 18 years, a large number of
full-sized datasets have been analysed using these procedures and the creep rupture strength
values have been used in European Design and Product Standards and within European industry
for design and life assessment. Nevertheless, in 18 years there have been many changes to both
the software which can be used to fit creep rupture data and to the membership of ECCC
Working Group 1 and in addition many observations have been made regarding the effectiveness
of the ECCC procedures. It was therefore decided that the effectiveness of the original
procedures would be re-evaluated by the current members using the most up-to data methods for
Creep Rupture Data Assessment (CRDA) and then the ECCC Recommendations would be
reissued. Four large multi-heat, multi-temperature working datasets on 2¼Cr1Mo, 11CrMoVNb,
18Cr11Ni and 31Ni20CrAlTi steels have been used for this re-evaluation.
