— The multiple specimen technique was developed to measure the crack growth fracture resistance of a through axial crack in a pressurised pipe and the results compared with data measured from test specimens. The comparison indicates that there is no significant difference between pipe and specimen behaviour. The results are also compared with elastic‐plastic three‐dimensional finite element analyses of the pipe and the R6 failure assessment curve. Reasonably good agreement was found between the experimental results and finite element analyses. The experimental results all lie outside the material specific failure assessment curve of the R6 structural integrity assessment procedure.
