Sec.  1068.415  How do I test my engines?

    (a) Use the test procedures specified in the standard-setting part 
for showing that your engines meet emission standards. The test order 
will give further testing instructions.
    (b) If no test cells are available at a given facility, you may make 
alternate testing arrangements with our approval.
    (c) Test at least two engines in each 24-hour period (including void 
tests). However, if your projected U.S. nonroad engine sales within the 
engine family are less than 7,500 for the year, you may test a minimum 
of one engine per 24-hour period. If you request and justify it, we may 
approve a lower testing rate.
    (d) Accumulate service on test engines at a minimum rate of 6 hours 
per engine during each 24-hour period. The first 24-hour period for 
service accumulation begins when you finish preparing an engine for 
testing. The minimum service accumulation rate does not apply on 
weekends or holidays. You may ask us to approve a lower service 
accumulation rate. Plan your service accumulation to allow testing at 
the rate specified in paragraph (c) of this section. Select engine 
operation for accumulating operating hours on your test engines to 
represent normal in-use engine operation for the engine family.
    (e) Test engines in the same order you select them.
