Abstract
When a 1adle sample of an open-hearth charge was taken, from the angle of its chemical analysis value, the probability that the chemical representation value of the charge was above the lower limit of a given standard value or lay between the lower and uppe limits was sought for under various assumptions and the following points were clarified.
A.Relation between the probability of coming withil the standard value and the chemical representation value of the charge.
B. Relation between the probability and standard deviations of chemical compositions value in or between the charges.
