(1) Cetane number - A
minimum cetane number of 47.0 as determined by ASTM Standard Test Method

test shall be conducted. If the average result of the two tests is more than
560 microns, the sample does not conform to the requirements of this
part;
(h) Fuel oils
shall meet the most recent version of ASTM D-396, "Standard Specification for

by contacting the director.
(n) The
commissioner, upon making a determination that the implementation of an ASTM
fuel standard has the potential to result in a fuel shortage, may delay
implementation of the ASTM standard for up to one year subsequent to the formal
promulgation date by ASTM.
