This paper, which focuses on the practical work, is an extension of earlier work first presented at BINDT 2002 (Southport) and subsequently published in Insight(2, 3). This paper accompanies Part 4, the theoretical part of this new work, which was published in February's
issue of Insight. In essence, further macrographs were taken of the same planar flaws from the earlier work, in order to obtain more physical information about each flaw. In addition, information on other suitable planar flaws was included from a previous TWI study from welds in the thickness
range 10 mm to 50 mm. The effects of including all this additional information on the various practical analyses are presented here.
