METHOD OF DETERMINING NONCONFORMING ITEMS IN SAMPLE Russian patent published in 2024 - IPC G01R31/327 G01R31/01 H01H49/00 G05B23/02 

FIELD: measurement.

SUBSTANCE: invention relates to methods of non-destructive testing of sampling or batch of articles. According to the invention, a sample size N, a criterion of non-compliance of an article under given conditions, is set, according to which, when one of two different values of the controlled parameter P₁, P₂, P₁>P₂ is achieved under given conditions, the product is recognized as corresponding to the requirements, and when the other is achieved, it is not. Sample is connected to each sample in parallel to the outputs, the samples are connected in series. Places of samples with articles are numbered with serial numbers. Values of the parameters of the samples are set in the form of a geometric progression with denominator of 2 and an index equal to the number of the sample place without one. All items of the sample with samples are controlled and the total value of the controlled parameter is determined, divided by the value of the parameter of the first sample, the quotient is determined, and the integer nearest to it is determined. Integer closest to the quotient is presented in the binary number system, and the location of the nonconforming article is determined by the bit of this number, in which there is one, if achievement of value P₁ is considered to be nonconformity, or there is zero, if the P₂ value is considered to be nonconformity.

EFFECT: shorter time for inspecting a sample or batch with one inspection means.
