Current legally specified test procedures for measuring hydrocarbon and carbon monoxide concentrations in vehicle exhaust gases contain intrinsic test variables which significantly affect test results; these variables constantly hamper efforts to correlate test data generated at one or more exhaust emission test facilities; paper provides general description of more prominent test variables such as vehicle repeatability, test driver repeatability, instability of calibrating gases and changing ambient test conditions; in addition to describing test variables and their effects, paper describes success of various measures which were undertaken to reduce or eliminate influence of some of variables on test repeatability and facility correlation.
