2	Propane calibration standard gas	C₃H₈-0.22∽1.32% (10%LEL∽60%LEL)	Air	2L、4L、8L
3	Butane calibration standard gas	C₄H₁₀-0.19∽1.14% (10%LEL∽60%LEL)	Air	2L、4L、8L
4	Isobutane calibration standard gas	i-C₄H₁₀-0.18∽1.08% (10%LEL~60%LEL)	Air	2L、4L、8L
5	Ethanol calibration standard gas	C₂H₅OH-0.033∽1.65% (1%LEL∽50%LEL)	Air	2L、4L、8L
[Note]: According to the calibration procedures for combustible gas detection alarms, if the type of gas detected is not specified, it can be calibrated with isobutane or propane standard gas (k=2, u≤2%)
