An amendment has been made to BS 7910:2013, 'Guide to methods for assessing the acceptability of flaws in metallic structures', superseding earlier versions of the procedure.
The December 2013 update of BS 7910, which includes advice on non-destructive testing reliability and more advanced treatment of fracture, has been broadly welcomed by industry.
Extensive user experience over the year following its publication revealed a number of errors, mostly of a minor editorial nature, and ambiguities, leading to this amendment. Published in July 2015, the updated version is known as BS 7910:2013+A1:2015. The amendment, which was further updated to reflect some additional minor corrections in September 2015, will be issued free of charge to purchasers of BS 7910:2013.
The main technical change in the new amendment, arising from user feedback, is a complete change to the K-solution for semi-elliptical surface flaws in bars, as described in section M.10.3 of the procedure. Other amendments, mostly editorial, are clearly indicated by tags.
TWI's consultancy services, training materials and CrackWISE software will henceforth be based on Amendment 1.
