Gives a procedure to determine whether an analytical system for natural gas is satisfactory, assuming that a) the analytical and calibration methods are fully described; b) the analytical needs have been clearly defined, for the range and uncertainty of component concentration measurements, and the uncertainty of properties which may be calculated from these measurements; c) the procedure's intent to be applicable to gases with compositions which vary over ranges normally found in transmission and distribution networks.
