The Impact of Sample Measurement Error on Two Types of Risks Cannot Be Ignored: An Accurate Calculation Method for the Probability of Wrong Judgment of Inspection Batch
Abstract
Runsheng Tu
Measurement errors exist in samples. It can lead to misjudgment of individual conclusions and sample quality determination. Assuming that there is no measurement error, the risk determined is not the true risk borne by both the supplier and the buyer. The total risk borne by both the supplier and the buyer for quality misjudgment is determined by the probability of the event of batch misjudgment and the event of sample misjudgment. An accurate calculation method for detecting the probability of batch misjudgment is provided. A counting sampling inspection scheme considering the risk of misjudgment of sample test results is introduced. This provides direction for revising ISO 2859 standard.
