ISO 17025 queries (question 2. I do not understand the concept of measurement uncertainty. Can you help me with it?) at https://community.advisera.com/topic/iso-17025-queries/
Measurement uncertainty at https://community.advisera.com/topic/measurement-uncertainity/
 Also have a look at the ISO 17025 toolkit document template: Evaluation of Measurement Uncertainty Procedure at https://advisera.com/17025academy/documentation/evaluation-of-measurement-uncertainty-procedure/ This  covers the basic principles and steps to plan, measure and calculate the data required for an evaluation of measurement uncertainty. The two appendices related to the document, Measurement Uncertainty Checklist and Measurement Uncertainty Record support the process. I recommend you also look to your sector and suppliers for commonly used approaches.
