The creep clauses of BS7910

The creep parts of the BS7910 fitness-for-service procedure were first produced as PD6539 in 1994. Since then there have been significant developments in creep fracture mechanics. The current treatment of defects in the creep regime, as set out in BS7910, is described. The approach is straightforward to apply as illustrated by a worked example, adapted from that in an earlier version of the approach. The paper also discusses the use of BS7910 and future development needs.
