9.1.6 Requirements for Sample Gas
Flow rate:	0.5L / min ±0.2L / min
Temperature:	0 to 50˚C
Pressure:	10 kPa or less (Gas outlet side should be at
	atmospheric pressure).
Dust:	100 µg/Nm3 or less in particle size of 0.3
	µm or less.
Mist:	Not allowed
Moisture:	For sample gases NO, SO2, CO(0-200

	standard room temperature saturation
	point.
Corrosive component:	1 ppm or less
Standard gas for calibration:

1)Infrared-ray measurable component, standard O2 Zero gas: Dry N2

Span gas ; Each sample gas having concentration 90 to 100% of its measuring range recommended).

For external zirconia O2 sensor use the same calibration gas line:
