YB/T 4997-2022 (Rules for the use of calibration and quality control charts in spectrochemical analysis) is available as an English-translated PDF.

YB/T 4997-2022 — This standard specifies the procedures for the preparation of quality control charts for confirmation of spectrochemical analysis. Criteria for taking corrective action are specified; control is achieved through instrument-to-test verification of sample response values, which can be done concurrently with control charting.

This standard is specifically aimed at atomic emission spectrometry and can be used conditionally in other analytical methods. This standard is not applicable to the verification of calibration correctness.

The procedures described in this standard are not applicable to those that need to be calibrated when each set of data is measured.
