Evaluation of the Uncertainty of Determination Zinc in Cast Aluminum Alloy Ingots by Photoelectric Direct Reading Spectrometry

Abstract:

According to JJF 1059.1-2012 of Evaluation and Expression of Uncertainty, the uncertainty of determination zinc in cast aluminum alloys ingots samples by photoelectric direct reading spectrometry was evaluated. The uncertainty sources were analyzed and the relevant mathematical models were established. The influential factors of precision were dissected. Each of the standard uncertainty, the combined standard uncertainty, the expanded uncertainty and the confidence interval were anatomized.
