ISO 3448:1992, Industrial liquid lubricants -- ISO viscosity classification

Establishes a system of viscosity classification for industrial liquid lubricants and related fluids including mineral oils used as lubricants, hydraulic fluids, electrical oils and for other applications. The usual method for kinematic-viscosity determination is that specified in ISO 3104. There may be some pure chemicals and naturally occurring products, used as lubricants, which will not fall within the classification. This title may contain less than 24 pages of technical content.
