HJ 1099-2020 (English Version) PDF

Scope: This standard specifies the requirements for primary calibration of ambient air ozone monitoring, methods for calibrating ozone transfer standards with primary ozone standards, and their quality assurance and quality control. This standard is applicable to the value transfer of ozone transfer standards by primary ozone standards, primary calibration of ozone monitoring, and its quality assurance and quality control. Other ozone standard reference photometers can be calibrated to the ozone transfer standard with reference to this standard. 0～1000 nmol/mol Zero point noise ≤1.0 nmol/mol Minimum detection limit ≤2.0 nmol/mol Indication error ±4%FS Response time ≤5 min Voltage stability ±1%FS Influence of ambient temperature changes ((15～ 30)℃ temperature range) ≤1 nmol/mol/℃ 20% range precision
