Proposed updates to the buried-to-surface flaw characterization rules in the Annex E of BS 7910

BS 7910 “Guide to Methods for Assessing the Acceptability of Flaws in Metallic Structures” is undergoing revision for the 2019 edition. Updates are proposed for the Annex E flaw recharacterization guidance. The changes aim to make Annex E more applicable to real structures and to improve the synergy...
