Error analysis (at 2000 K)
| Quantity | Imprecision a | Inaccuracy b |
|---|---|---|
| Temperature | 0.5 K | 4 K |
| Voltage | 0.03% | 0.1% |
| Current | 0.03% | 0.1% |
| Heat capacity | 0.7% | 3% |
| Electrical resistivity | 0.6% | 2% |
| Hemispherical total emittance | 0.9% | 5% |
a
Imprecision refers to the standard deviation of a quantity as computed from the difference between the value of the quantity and that from the smooth function obtained by the least squares method. The quantities in the case of temperature, voltage, and current are the individual points measured in a single experiment, and in the case of heat capacity, electrical resistivity, and hemispherical total emittance are the results from all experiments as tabulated in the appendix.
b
Inaccuracy refers to the estimated total error (random and systematic).
