What are the requirements for certification of SmartCEMS®-60 PEMS under 40 CFR Part 60, PS-16?

The minimum data required for a SmartCEMS® PEMS model is from 3 to 5 days of data to build a successful model. The entire range of operations at various loads and including a startup and/or shutdown is typically required. The initial certification under PS-16 requires a 27-run relative accuracy test audit, with three quarterly audits, and statistical analysis of the data. The minimum quality assurance requirements for the first year are three quarterly audits, and every other year a single quarterly audit along with annual 9-minute RATA is required.
