CLASSIFICATION OF LUBRICANTS AND HYDRAULIC FLUIDS
Abstract
THE British Standard 4231 : 1967 “Viscosity Classification for Industrial Liquid Lubricants” together with BS 4475 : 1969 “Specification for Straight Mineral Lubricating Oils” constitute a real step forward for the lubrication world. Not only do they contribute clarity to their respective subjects, they also enable an overall classification of all lubricants and hydraulic fluids based on a common theme to be composed. BS 4231 enables the viscosities of all fluid lubricants including hydraulic media to be identified within one dimensionally rational scale. Though it is specifically for straight mineral oils, BS 4475 suggests a segregation of quality levels appropriate to other than straight oils.
