This test plan sets forth the agreed upon processes and methodologies to be utilized to develop additive, brake-specific, data-driven measurement allowance for PM emissions measured by PEMS as required under the HDIUT regulatory program. As detailed in this test plan, there is a clear consensus on what components of measurement error are intended to be covered by the measurement allowance. Namely, the allowance is to be calculated in a manner that subtracts lab error from PEMS error. Specifically, utilizing Part 1065 compliant emissions measurement systems and procedures for both the lab and PEMS, the lab error associated with measuring heavy-duty engine emissions at stabilized steady-state test points within the NTE zone, will be subtracted from the PEMS error associated with measuring heavy-duty engine emissions utilizing PEMS over events under a broad range of environmental conditions. This subtraction will yield PEMS minus laboratory measurement allowance. The experimental methods and procedures specified in this test plan for determining, modeling, and comparing each of the various components of measurement error are designed to generate statistically robust data-driven measurement allowance for the PM emissions.
