[Code of Federal Regulations] [Title 40, Volume 30] [Revised as of July 1, 2004] From the U.S. Government Printing Office via GPO Access [CITE: 40CFR1065.5] [Page 649-650] TITLE 40--PROTECTION OF ENVIRONMENT CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED) PART 1065_TEST PROCEDURES AND EQUIPMENT--Table of Contents Subpart A_Applicability and General Provisions Sec. 1065.5 Overview of test procedures. (a) Some of the provisions of this part do not apply to all types of engines. For example, measurement of particulate matter is generally not required for spark-ignition engines. See the standard-setting part to determine which provisions in this part may not apply. Before using this part's procedures, read the standard-setting part to answer at least the following questions: (1) How should I warm up the test engine before measuring emissions? Do I need to measure cold-start emissions during this warm-up segment of the duty cycle? (2) Do I measure emissions while the warmed-up engine operates over a steady-state schedule, a transient schedule, or both? (3) What are the speed and load points of the test cycle(s)? (4) Which exhaust constituents do I need to measure? (5) Does testing require full-flow dilute sampling? Is raw sampling acceptable? Is partial-flow dilute sampling acceptable? (6) Do any unique specifications apply for test fuels? (7) What maintenance steps may I do before or between tests on an emission-data engine? (8) Do any unique requirements apply to stabilizing emission levels on a new engine? (9) Do any unique requirements apply to testing conditions, such as ambient temperatures or pressures? (10) Are there special emission standards that affect engine operation and ambient conditions? (11) Are there different emission standards that apply to field testing under normal operation? (b) The following table shows how this part divides testing specifications into subparts: ------------------------------------------------------------------------ Describes these specifications or This subpart... procedures... ------------------------------------------------------------------------ Subpart A...........................
