1.Precision (short-term stability)
Test method: Select samples of different concentration ranges of typical elements, continuously excite 10 points, and evaluate the precision of the direct reading spectrometer by the RSD of the data.
Elements to be tested and concentration range:
After the direct-reading spectrometer is stable, under the optimal working conditions of the instrument , it is continuously excited 10 times to measure the content of the representative element in a low alloy steel standard substance GBW01328 ~ GBW01333 (or GBW01211 ~ GBW01216), and the average and relative standard deviation are calculated. Repeatability.
3: Verification of stability
After the direct reading spectrometer is turned on and stable, a certain low alloy steel standard substance GBW01328 ~ GBW01333 (or GBW01211 ~ GBW01216) is excited to measure the measured elements. Within 4 hours, the measurement was repeated more than 15 minutes, and the measurement was repeated 6 times (the period is no longer standardized). The mean and relative standard deviation are calculated as stability.
The reproducibility is the stability of the direct-reading spectrometer. The national standard stipulates that the reproducibility must be tested within 4 hours.
