The recently developed European flaw assessment procedure SINTAP is applied to a total of 88 full scale pipe tests (burst tests) with through-wall and surface cracks subjected to internal pressure. Based on the experimental results various analysis levels of SINTAP are discussed with respect to their potential for predicting the failure loads and the margins of conservatism. Different shape functions from Newman & Raju, Zahoor and API 579 were used for the assessment.
