(a) in the case of volume measurement, shall be expressed as the number of cubic metres the gas would occupy at the standard conditions, namely, at a temperature of 15°C and at an absolute pressure of 101.325 kPa; and
(2) Where volume is measured under conditions of temperature and pressure other than the standard conditions described in paragraph (1)(a), the volume shall be converted to the equivalent under the standard conditions, in accordance with the Ideal Gas Laws, and shall be corrected for deviations from the Ideal Gas Laws in accordance with subsection (3), where the amount of the deviation exceeds one per cent.
