All Type A and Type B standard uncertainties must be combined to calculate combined standard uncertainty and then an expanded uncertainty. The specific mathematical, statistical aspects are not part of the scope of the ISO 17025 Academy toolkit. I suggest you look to sector guidelines and the references in the ISO 17025 Toolkit. The Evaluation of Measurement Uncertainty Procedure and associated checklists at https://advisera.com/17025academy/iso-17025-documentation-toolkit/ guides you on what is required to meet ISO 17025 requirements.
