APPENDIX A
A.3 ADDITIONAL REQUIREMENTS FOR FINISHED FUEL CONTAINING FT-SPK.
A.3.1 Chemical and physical requirements. The chemical and physical properties of finished fuel
containing FT-SPK (FT-SPK must meet requirements of Table A-I and FT-SPK content of finished fuel
may not exceeded 50 volume percent) shall be in accordance with those specified in Table I and in
addition those specified In Table A-II.

NOTES:
1. A condenser temperature of 0 °C to 4 °C (32 °F to 40 °F) shall be used for the distillation by ASTM D86.
2. Referee Test Method.
3. Distillation property criteria are specified in ASTM D86 scale units. ASTM D2887 results shall be
converted to estimated D86 results by application of the correlation in Appendix X5 of D2887 for
comparison with the specified property criteria. Distillation residue and loss limits provide control of the
distillation process during the D86 test method and do not apply to D2887.
4. The temperature difference between the temperature that demarks the 10 percent recovered point and
the temperature that demarks the 50 percent recovered point must be at least 15 °C.
5. The temperature difference between the temperature that demarks the 10 percent recovered point and
the temperature that demarks the 90 percent recovered point must be at least 40 °C.
