Sammendrag
21 laboratories in 15 countries participated in intercalibration 9105. Basedon the general target accuracy of +/- 20 %, 90 - 100 % of the results were acceptable for all the main components, only 0-2 result pairs lying outside the accuracy limit. Most results are even lying within much narrower limits. For pH only 35 % of the result pairs were acceptable in relation observed for pH are caused by systematic errors.
