ASTM D2881-03(2009)

Metal working may be divided into two general types of processes, metal deformation and metal removal or cutting. This classification lists the various types of fluid and non-fluid materials used to directly cool and lubricate in both types of metalworking processes. It is intended for use by those in metalworking or related industries who want to differentiate these materials. It is up to the user of this classification to determine the relevance of the items listed with respect their application.

1.1 This classification of metal working fluids and related materials is designed to standardize and consolidate the terminology, nomenclature, and classification of these products.

1.2 Metal working fluids includes both metal removal and forming fluids. These are the coolants and lubricants associated with both types of processes.

1.3 This classification implies no evaluation of product quality or suitability for a given metalworking operation.
