EPA CFR Part 1066 will allow PFD measurement: 1. PFDs reduce size, complexity and cost of dilution systems. Results consistent with full flow tunnel (precision, accuracy): 1. Proportionality requirements satisfactory. HEV/low exhaust flow conditions sampled proportionally: 1. Extraction flow set to zero for low (< 40 lpm) exhaust flow. One Filter results equivalent to standard FTP 3 Filter: 1. Opportunities for mitigating weighing process variability.
