To achieve a PoD of 90% with 95% confidence, a minimum of 29 samples is typically required for simple assessments. However, DNV-RP-F118 often requires significantly more data to ensure reliability in complex weld geometries. For example, for double V submerged arc welds, the practice recommends at least 91 samples . dnv-rp-f118
