2、st reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This specification(see Note 1)covers grades of fuel oilintended for use in various types of fuel-oi
3、l-burning equipmentunder various climatic and operating conditions.These gradesare described as follows:1.1.1 Grades No.1 S5000,No.1 S500,No.1 S15,No.2S5000,No.2 S500,and No.2 S15 are middle distillate fuelsfor use in domestic and small industrial burners.Grades No.1S5000,No.1 S500,and No.1 S15 are
4、particularly adapted tovaporizing type burners or where storage conditions requirelow pour point fuel.1.1.2 Grades B6B20 S5000,B6B20 S500,and B6B20S15 are middle distillate fuel/biodiesel blends for use indomestic and small industrial burners.1.1.3 Grades No.4(Light)and No.4 are heavy distillatefuel
5、s or middle distillate/residual fuel blends used incommercial/industrial burners equipped for this viscosityrange.1.1.4 Grades No.5(Light),No.5(Heavy),and No.6 areresidual fuels of increasing viscosity and boiling range,used inindustrial burners.Preheating is usually required for handlingand proper
6、atomization.NOTE1For information on the significance of the terminology andtest methods used in this specification,see Appendix X1.NOTE2A more detailed description of the grades of fuel oils is givenin X1.3.1.2 This specification is for the use of purchasing agenciesin formulating specifications to
7、be included in contracts forpurchases of fuel oils and for the guidance of consumers of fueloils in the selection of the grades most suitable for their needs.1.3 Nothing in this specification shall preclude observanceof federal,state,or local regulations which can be morerestrictive.1.4 The values s
8、tated in SI units are to be regarded asstandard.1.4.1 Non-SI units are provided in Table 1 and Table 2 andin 7.1.2.1/7.1.2.2 because these are common units used in theindustry.NOTE3The generation and dissipation of static electricity can createproblems in the handling of distillate burner fuel oils.
