PART 1065_ENGINE-TESTING PROCEDURES--Table of Contents
 
             Subpart A_Applicability and General Provisions
 
Sec.  1065.5  Overview of this part 1065 and its relationship to the standard-setting part.

    (a) This part specifies procedures that apply generally to testing 
various categories of engines. See the standard-setting part for 
directions in applying specific provisions in this part for a particular 
type of engine. Before using this part's procedures, read the standard-
setting part to answer at least the following questions:
    (1) What duty cycles must I use for laboratory testing?
    (2) Should I warm up the test engine before measuring emissions, or 
do I need to measure cold-start emissions during a warm-up segment of 
the duty cycle?
    (3) Which exhaust gases do I need to measure?
    (4) Does testing require full-flow dilute sampling? Is raw sampling 
prohibited? Is partial-flow sampling prohibited?
    (5) Do any unique specifications apply for test fuels?
    (6) What maintenance steps may I take before or between tests on an 
emission-data engine?
    (7) Do any unique requirements apply to stabilizing emission levels 
on a new engine?
    (8) Do any unique requirements apply to test limits, such as ambient 
temperatures or pressures?
    (9) Is field testing required, and are there different emission 
standards or procedures that apply to field testing?
    (10) Are there any emission standards specified at particular 
engine-operating conditions or ambient conditions?
    (11) Do any unique requirements apply for durability testing?
    (b) The testing specifications in the standard-setting part may 
differ from the specifications in this part. In cases where it is not 
possible to comply with both the standard-setting part and this part, 
you must comply with the specifications in the standard-setting part. 
The standard-setting part may also allow you to deviate from the 
procedures of this part for other reasons.
    (c) The following table shows how this part divides testing 
specifications into subparts:
