Foreword
Committees responsible
Section one. The background to remanent life
assessment
   Introduction to topics covered in the other sections.
Section two. Operating history
   Maintenance history, expired fraction of life,
   preliminary screening, rigorous analysis of critical
   areas, measurement of metal temperatures, calculation
   of stress levels, use of creep rupture data, life
   fraction rule, accuracy of estimates of fractional
   life
Section three. Physical examination and interpretation
of observations
   Visual inspection, non-destructive testing,
   dimensional checks, timing of examinations,
   interpretation of observations, estimation of
   remanent life from measurements, use of creep data,
   determining the cause of cracking
Section four. Metallographic techniques
   Use of small samples or in-situ techniques,
   measurement of microstructural features controlling
   creep, measurement of cavitation or cracking,
   application of proving data, effects of condition of
   starting material
Section five. Post-exposure tests
   Use of on-going research data, selection of suitable
   test procedure, tensile tests, fatigue tests, creep
   tests, life fraction rule, accuracy of estimates of
   remaining life
Section six. Environmental effects
   Effects of environmental attack on the creep rate of
   materials, deviations from predicted rates of attack,
   effects of corrosion allowances, examples of
   environmental attack, transient environmental
   conditions, consequences of attack
Section seven. Combined creep and fatigue
   Behaviour under conditions of creep or fatigue alone,
   reduction of life due to combined effects,
   simplification of analyses of effects, degree of
   interaction of creep and fatigue, available data, use
   of material examination and testing
Section eight. Statistical methods
   Application to a large number of identical
   components, acceptance of a limited number of
   failures, scatter of parameters and resulting
   uncertainties, prediction of failure rates,
   constraints on the successful application of the
   technique
