Gas Detector Alarm Calibration Specification Requirements
Regulation 5.5 of the "Regulation for Calibration of Combustible Gas Detectors" (JJG693-2011) stipulates: The calibration cycle for combustible gas detection and alarm instruments: Generally, the calibration cycle of the instrument should not exceed one year. If there is any doubt about the measurement data of the instrument, or if the instrument has been replaced with major components or repaired, it should be sent for calibration promptly.
Section 3.5 of the "Regulations for the Use of Combustible Gas Detection and Alarm Systems" (SY6503-2000) stipulates: The combustible gas detection and alarm systems in use shall be calibrated regularly as required.
Section 7.2.1 of "Code for the Installation of Toxic Gas Devices in Workplaces" (GBZ/T223-2009) stipulates: Calibration of detection and alarm devices should be performed regularly according to the manufacturer's specified time and procedures.
Section 3.4 of "Regulations for the Use of Combustible Gas Detectors" (SY6503-2000) stipulates: Combustible gas detectors for installation and use should have measurement instruments manufactured by recognized agencies and **explosion-proof performance**.
