Notes:
1. Generally, effect dates of standards are for engines built on or after 1January of the respective year, except where noted.
2. All standards are based upon ISO 8178C18-mode test for variable-speed engines and D25-mode test for constant-speed engines. Transient test required beginning with 2011phase-in.
3. Separate NOx and HC standards separated by a "/".Combined NOx and HC standards denoted in parenthesis "()".
4. Smoke requirements:U.S:On-highway federal test procedure. Europe -None, but some OEM's require R24.03certification. Japan has unique smoke standard and procedure. 5. Generator sets in Europe are required to meet Stage II standards beginning 1January 2007.
6. The U.S. on-highway consent decree includes a one year pull ahead to 2005of the nonroad Tier 3requirements for engines 300-749hp. Note slight power range discrepancy. 7. For U.S.Tier 4, optional 0.30g/kW-hrPM standard for engines 37-55kW in 2008. Selecting this option allows a 1year delay of Tier 4Final implementation from 2012to 2013. 8. For U.S. Tier 4, "Split-family" standards are shown for 56-560kW. Optional "Phase-in" standards for NOx are permitted by EPA.
9. CANADA -MOU with Cummins requires Tier 1engines built on or after 1January 2000. In 2004, Canada formally proposed to require EPA compliant engines beginning in 2006.
10. KOREA -U.S. EPA Tier 1and Tier 2equivalent standards phased in beginning in 2004and 2005respectively for engines 19-560kW. Vehicle certification rather than engine certification.
