ABSTRACT Working group 1 of the European Creep Collaborative Committee (ECCC-WG1) was formed towards the end of 1992 to develop and recommend the procedures to be used by ECCC for the generation, collation and assessment of creep deformation, stress rupture and stress relaxation data. More recently, as the scope of ECCC activity has broadened, other working groups have contributed to the suite of recommendation volumes, of which there are now eight. ECCC Recommendations Volume 1 introduces the eight technical volumes and provides an overview of their content.

ECCC may from time to time re-issue the respective volumes in response to new developments. The user is advised to consult the appropriate Document Controller for confirmation that reference is being made to the latest issue.

FOREWORD ECCC Volume 1 overviews the recommendations contained in eight technical volumes providing guidance on terminology, data generation, information-collation/exchange, and data assessment relating to creep deformation and rupture in uniaxial and multi-axial loaded testpieces/components, both without and with pre-existing defects. VOLUME 2 VOLUME 3 VOLUME 4 VOLUME 5 VOLUME 6 VOLUME 7 -
Terms and terminology Recommendations for data acceptability criteria and the generation of creep data Guidance for the exchange and collation of creep data Guidance for the assessment of uniaxial creep data Residual life assessment and microstructure Guidance for the assessment of creep crack initiation in testpieces and components VOLUME 8 - Guidance for the assessment of multi-axial creep test data VOLUME 9 - High temperature component analysis The suite of volumes has been specifically prepared for use within ECCC. Nevertheless, they represent the state-of-the-art for industrial creep data acquisition and manipulation, and their content is therefore of interest and is recommended to a much broader spectrum of user beyond ECCC.
