GB 12358-2024 "General Technical Requirements for Environmental Gas Detection and Alarm Instruments in Workplace" is an important standard.
Intended to standardize the performance, functions, and testing methods of environmental gas detection alarm instruments used in work places.
The standard was published in 1990 and has undergone several revisions.
The new version is GB 12358-2024, which will be officially implemented on June 1, 2025.
This standard applies to the production and use of gas detection and alarm instruments for flammable gases, toxic and harmful gases, and oxygen in work environments.

What factors can affect the calibration cycle of a flammable gas detector alarm?
Manufacturer Requirements: Different manufacturers may have varying inspection cycle requirements for flammable gas detectors. Therefore, when purchasing equipment, carefully review the product manual to understand the specific requirements of the manufacturer.
Equipment Usage Environment: The operating environment of the alarm directly affects its inspection cycle. If the equipment is frequently exposed to high concentrations of harmful gases, high or low humidity, or high or low temperatures for extended periods, its inspection cycle may be shortened accordingly.
‌Equipment Maintenance Status: The condition of equipment maintenance is also a significant factor affecting the inspection cycle. If the equipment faces issues such as battery depletion and sensor aging over a long period, its inspection cycle will correspondingly shorten.

Gas Standard Material
The gas standard substance used should be of the same type as the gas measured by the instrument, such as methane or ethane, or alternative alcohols can be used for gas standards. If the instrument does not specify the type of gas being measured, the concentration of the gas at the set point should be approximately 60% of the full scale, using a standard substance. The uncertainty of the expanded gas standard substance is not significant (%), and the standard gas should be diluted. The flow rate indication error of the repeatability dilution device should not be greater than 0.1%. The concentration unit of the diluted gas standard substance should be converted to match the unit of the tested instrument, and should not exceed 0.1%.
