This work described three test methods employed to assess the condition of components in high temperature power generation plant. These are stress relaxation on miniature samples from service aged material, low cycle fatugue testing by strain control and Young's Modulus determination by an impulse excitation technique. Data are presentated from tests on 2.25Cr-1Mo virgin and service-aged steel and the applciation of data to life assessment procedures us discussed.
