7、UIREMENT) A.1 CHARACTERISTICS and APPLICATIONS These fuels are intended for use as follows: A.1.1 Factory Fill or Service Accumulation Fuel A.1.1.1 Grade 1 Winter Fuel: Factory Fill or Service Accumulation test fuel, for use at low ambient temperatures of +10 to -25F (-12 to -32C). For temperatures
8、below -25F (-32C), a fuel meeting the requirements of Commercial Item Description (CID) AA-52557, Low Temperature Diesel Fuel Blend F-65 should be used. The Grade 1 diesel fuel is normally provided with a sulfur content of 7 - 15 parts per million (ppm). A.1.1.1.1 Grade 1C(MP) is a winter fuel used
9、by Engine Group at Melrose Park Engineering. A.1.1.1.2 Grade 1C Winter Fuel: Factory Fill or Service Accumulation test fuel for use at the same ambient temperature ranges as the Grade 1 fuel but, having an ultra low sulfur content of 7-15 ppm. A.1.1.2 Grade 2 Summer Fuel: Factory Fill or Service Acc
10、umulation test fuel for normal ambient temperature operations. This fuel, with or without minimum aromatics content, will meet EPA requirements for Service Accumulation tests. The Grade 2 diesel fuel is normally provided with a sulfur content of 7-15 parts per million (ppm). A.1.1.2.1 Grade 2C(MP) i
11、s a summer fuel used by Engine Group at Melrose Park Engineering. A.1.1.2.2 Grade 2C is a Factory Fill or Service Accumulation test fuel for use at the same ambient temperatures as the Grade 2 fuel but, having an ultra low sulfur content of 7 - 15 ppm. A.1.2 Emission Certification Fuel A.1.2.1 Grade
12、 2: This fuel will meet EPA requirements for exhaust emission testing. The fuel is available in an ultra low sulfur version with sulfur content at 8-14 ppm.
