Common use of Calibration of Gas Analysis Equipment Clause in Contracts

Calibration of Gas Analysis Equipment. The on-stream Gas Analysis Equipment shall be calibrated in accordance with the approved validation procedures at appropriate intervals with Standard Gas prepared by gravimetric means or traceable by recognised procedure to an appropriate gravimetrically prepared standard mixture and containing, as a minimum, nitrogen, carbon dioxide, methane, ethane, propane and butane. However, hydrocarbons heavier than butane should not be calculated from the butane content alone and so the Gas Analysis Equipment must allow the responses of hydrocarbons heavier than butane, with the Standard Gas also containing appropriate amounts of the heavier hydrocarbons.
