gas contained 12% CO2 by volume.

Meaning of concentration of NO2
 (3) In Table 1, mention of a concentration of NO2 at a particular oxygen reference concentration is a mention of the measured concentration of NO2 adjusted in accordance the following formula:
where:
measured NO2 concentration means the measured concentration of oxides of nitrogen, expressed as NO2.
MOC means the measured oxygen concentration.
ROC means the particular oxygen reference concentration.

Accepted limits—measurement assumptions
 (4) In Table 1, the expression, in column 4 of Table 1, of a volume of gas or vapour assumes the gas or vapour to be measured dry, at a temperature of 0 C. and at an absolute pressure of one atmosphere (101.325 kPa).

Measurement of rate of emission
 (5) For Table 1, the rate of emission of a substance is assumed to be ascertained:
 (a) unless the contrary intention appears, by measurement of samples:
 (i) at, or taken from, the point of emission into the air; and
 (ii) that are undiluted; and
 (b) in accordance with the method of measurement, analysis or monitoring mentioned for the substance in column 5.
