             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:
