![]() When No.1 and No2 diesel are blended for low temperature operability the minimum specification is reduced to 38☌ (100☏). If enough contamination of the higher volatile material is present the cetane number will likely be adversely affected which may result in poor engine performance. When the flash point does not meet the minimum specification, this provides an indication that the fuel may be contaminated with a more volatile product. Flash point is generally specified for legal and safety concerns in regards to fuel handling and storage. 2-D diesel fuel grade.įlash Point – Flash Point measures the temperature at which vapors on the surface of the fuel will ignite when exposed to a flame. While Table 1 encompasses the detailed requirements for several grades of Diesel Fuel, this overview will focus primarily on the No. Part III will provide further guidance on other common diesel fuel tests performed that are not specified in the Table 1 requirements. Part I and II will contain an overview of table 1 from ASTM D 975 Standard Specification for Diesel Fuel Oils. ESource Archive Subscribe to eSource Follow Us
