| Abstract: | Phosphorus content in ferromolybdenum was determined according to the second method in GB/T 5059.6-2007.The sources of the uncertainty in measurement were analyzed and discussed,moreover,the uncertainty in measurement was calculated and evaluated.The expanded uncertainty of this method was 0.002 % with under confidence probability of 95%. |
