Calibration gas
☞
The calibration gases must be clean, non-corrosive, free from oil and
condensates and compatible with the materials listed in Appendix A6.
☞
For optimum calibration results, the calibration gas flow rate/pressure should
be the same as the flow rate/pressure of the gases to be sampled.
