Lavrenova D. Accuracy Increasing Of Tests Laboratories Professional Level Evaluation

Dissertation is devoted to question of tests unity maintain by elaboration of inter-laboratory comparative tests, which is direct to tests laboratories professional level evaluation. The cross-scheme inter-laboratory tests methods, which is allow tests laboratories professional level evaluation in absents of basic laboratory and single standard specimens, were offered. Introducing methods allow separated trueness evaluation of tests laboratory works and control specimens set homogeneous. Limits conditions for methods use in case of small-value tests were received. It is necessary preliminary tests results processing by discard searching for observe limits conditions. It is shown insufficient sensibility of known discard search criterions for use in case of small-value selection. Relative distances criterion, which is allow to obtain data selection with disperse according to assign tests accuracy, was synthesis. The limits conditions of cross-scheme inter-laboratory tests methods in case of small-value tests for relative distances criterion critical value was offered.
