S5000 grades correspond to the so-called “regular” sulfurgrades, the previous No. 1-D and No. 2-D. S500 grades correspond to the previous “Low Sul

S15 grades were not in the previous grade systemand are commonly referred to as “Ultra-Low Sulfur” grades or ULSD.1.2 This specification, unless otherwise provided by agreement between the purchaser and the supplier, prescribes the requiredproperties of diesel fuels at the time and plac

46、 that previously held a high or intermediate vapor pressure product (such asgasoline or solvent) without prior compartment cleaning treatment and inert gas purging; and the reverse procedure where a highvapor pressure product is added to a container that previously held a low vapor pressure product.
47、3.1.4.1 DiscussionSince middle distillate fuels have flash points above 38 C, during normal distribution of these fuels, the atmosphere above thefuels in a container such as a tanker truck, rail car, or barge, is normally below the lower explosive limit, so there is low risk offire or explosion shou
48、ld an electrostatic discharge (spark) occur. However, when the previous load in the compartment was avolatile, flammable fuel such as gasoline, and if some residual fuel vapor or mist remains in the compartment, and the containerhas a mixture of air and fuel vapor or mist (that is, not purged with a
49、n inert gas), then there is a risk that the atmosphere in thecontainer being filled could be in the explosive range creating a hazard should an electrostatic discharge occur.3.2 Definitions of Terms Specific to This Standard:3.2.1 S(numerical specification maximum)indicates the maximum sulfur content, in weight ppm (g/g), allowed by thisspecification in a diesel fuel grade.3.2.1.1 DiscussionOf the seven diesel fuel grades specified in this standard, six have important distinguishing maximum sulfur regulatoryrequirements. These are Grades No.
