The National Metrology Technical Specification JJF(ShiJie) 047-2021, titled "Hydrogen Fluoride Gas Detection Alarm Calibration Specification," was officially released on December 2, 2021. This standard aims to provide guidelines for the calibration and verification of hydrogen fluoride gas detection alarm devices. It specifies the procedures and requirements necessary for ensuring the accuracy and reliability of these instruments used in various industrial settings where exposure to HF gas could be a significant safety concern.
The implementation date of this technical specification is April 1, 2022. The document covers essential aspects such as calibration methods, measurement uncertainties, and performance evaluation criteria for hydrogen fluoride detection alarms. It also includes detailed descriptions of test conditions, equipment requirements, and reporting procedures to ensure uniform application across different regions and industries within China.
Adherence to JJF(ShiJie) 047-2021 is crucial for maintaining high standards in occupational safety and health management systems where monitoring hydrogen fluoride concentrations in the air is vital. This standard plays a key role in protecting workers from potential respiratory hazards associated with prolonged exposure to HF gas.
