In order to make the proficiency test a meaningful instrument of quality assurance, there are lower limits for the size of the participant field. As a rule, a reliable statistical evaluation can only be carried out with the participation of a sufficient number of participants. Even if this case does not occur very frequently with us, we therefore reserve the right to cancel an experiment if there are doubts about the significance or quality of the evaluation. In these cases, the participants are contacted and a solution is sought that meets all interests. Our order confirmation will include those proficiency tests which will take place to the planned extent and on the scheduled date.
