GB/T 18403.1-2001

This standard specifies the general rules for expressing the performance of gas analyzers, covering terminology, test conditions, and methods for stating accuracy, repeatability, and response time. It is applied in industrial process control, environmental monitoring, and laboratory testing contexts where manufacturers and users need a uniform basis for specifying and comparing the capabilities of gas analysis instruments. The standard ensures consistent performance declarations across different analyzer types, such as those for measuring oxygen, carbon dioxide, or toxic gases.
