1/ Naturally-occurring sulfur is preferred. If additional sulfur is required, supplementation
shall only be achieved by blending sufficient amounts of ditertiary butyl disulfide to the
finished fuel.
2/ See appendix A. If the fuel contains cetane improver additives, this limit shall apply
only to the base fuel prior to addition of cetane improver.
3/ ASTM D613 is the referee method for determining cetane quality. ASTM D976 and
ASTM D4737 are permitted as alternates. If cetane improvers (as determined by the
method in appendix A) or non-naturally-occurring sulfur compounds have been
utilized, only ASTM D613 shall be permitted.
3.3.2 Type II referee fuel. The finished type II referee fuel which meets the min
requirements of MIL-DTL-83133, shall conform to the requirements specified in table II.
