1.1 This classification is applicable to all petroleum-base fluid lubricants and to those nonpetroleum materials which may be readily blended to produce fluid lubricants of a desired viscosity, that is, lubricants for bearings, gears, compressor cylinders, hydraulic fluids, etc.

1.2 This classification is applicable to fluids ranging in kinematic viscosity from 2 to 1500 cSt (mm /s) as measured at a reference temperature of 40&#176C. Expressed in approximate equivalents, the range would be 32 to 7000 SUS. In the category of petroleum-base fluids, this covers the range from kerosine to heavy cylinder oils. </p> <p>1.3 Fluids of either lesser or greater viscosity than the range described in 1.2 are at present seldom used as industrial lubricants. Should industrial practices change, then this system, based on a mathematical series of numbers, may be extended to retain its orderly progression. </p>
