For the purpose of testing the gas under this chapter, a cubic foot of gas shall be taken to be that amount of gas which occupies the volume of one cubic foot [28.3168 liters] when saturated with water vapor at sixty degrees Fahrenheit [15.56 degrees Celsius] and under a pressure equal to that of thirty inches [7.62 centimeters] of mercury at a temperature of thirty-two degrees Fahrenheit [0 degrees Celsius]. For the purpose of measurement of gas to a customer, a cubic foot of gas shall be taken to be that amount of gas which occupies a volume of one cubic foot [28.32 liters] under the conditions existing in such customer's meter as and where installed; provided, however, that when gas is metered at a pressure more than twelve inches [30.48 centimeters] of water column in excess of the prevailing barometric pressure (by agreement with the customer or with the written approval of the commission), the volume of gas metered shall be computed on the basis of the mean pressure in the utility's low-pressure system, or other basis ordered by the commission.
