post-test results is less than 2 per cent of the calibration gas value.
The NOx analyser shall be in the NO mode so that the calibration gas does not pass through the converter.
NO and purified nitrogen the amount of NO2 contained in this calibration gas must not exceed 5 per cent of the NO content.
