Together, Volumes 05.01 through 05.04 feature over 630 standards, including specifications and test methods that fix standard property requirements for fuels, oils, solvents, and hexane. They also feature standard procedures for evaluating the properties of motor, diesel, biodiesel, aviation fuels, solvent hexane, and naphtha. Other standards focus on distillate and residual fuel oil, kerosine and illuminating oils. Some set down procedures for evaluating such properties as carbon residue, viscosity, cloud point, density, flash point, and sulfur content. Standard procedures detail how to measure the properties of natural and liquefied petroleum, pure light hydrocarbons, crude petroleum, wax and petrolatum, and hydraulic fluids. Tests and practices for evaluating the properties of film lubricants, lubricating greases, lubricating oil, used oils, cutting oils, and turbine oils appear under the heading of lubricants.
