title: [Precision control in blood alcohol determination].
abstract: The German supreme court (BGH [1]) summons that by proclaiming four or five single measuring values of every blood alcohol determination to prove that the resulting standard deviation lies under the highest amount stated in the official verdict of 1989 (10). On the one hand the control of the proceedings must be guaranteed by the successful participation of the ring tests, yet on the other hand the evidence to retroactively prove the accuracy of every blood alcohol determination from it's single values is always called for anew. In the example case the average value is 1.11 g/1000, the standard deviation is 0.036 g/1000. The standard deviation summoned by the BGH (1) is thereby exceeded. On account of the fundamental scientific regularies the parameter standard deviation is not qualified to retroactively verify the required accuracy of the procedure by means of the single values. The blood alcohol result in question can be used without proviso. A reduction of the present approved 10% variation of the single values is not significant. Only according to todays accuracy requirements does this limit nearly appear to be appropriate.
