FINAL REGULATION ORDER TEST PROCEDURES

Note: This appendix shows the entirety of regulatory amendments to the test 

procedures titled below, which were approved by the Air Resources Board on 

December 16, 2011, and refined via subsequent conforming modifications 

authorized under Resolution 11-41. The source for these test procedures is 

Part 1039 of the “California Exhaust Emission Standards and Test Procedures 

for New 2008 and Later Tier 4 Off-Road Compression-Ignition Engines, 

Part I-C” (Part I-C), adopted October 20, 2005. These amendments are 

formatted in a style to indicate changes from the existing test procedures. All 

existing language is indicated by plain type. All additions to the existing 

language are indicated by underlined type (except that some existing headings 

within the test procedures were underlined originally for emphasis, and remain 

so, and thus do not constitute new language). All deletions to the existing 

language are indicated by strikeout. Only those sections containing the 

modifications from the existing language are included. All other portions remain 

unchanged and are indicated by the notation [ * * * * * ] for reference. If there 

is any conflict between the provisions of this document and the California 

Health and Safety Code, Division 26, or Title 13 of the California Code of 

Regulations (CCR), the Health and Safety Code and Title 13 apply.
