1) Standardised volumes and flow rates are referred to a temperature of 273°K and a pressure of 101.323 kPa.
2) The concentrations of pollutants are referred to a theoretical oxygen content equal to 13% viv.
3) The measurements, samplings and subsequent lab analyses have been carried out by means of instruments
calibrated according to acknowledged or primary standards of reference.
4) The lab management is ready to supply further explanations about the calculation methods of measurement
uncertainly combined with the results expressed.
5) The results represent the average values of all instrumental tests performed on the field.
