1、Designation: D2881 03 (Reapproved 2009)D2881 12Standard Classification forMetal Working Metalworking Fluids and Related Materials1This standard is issued under the fixed designation D2881; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revi
2、sion, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope Scope*1.1 This classification of metal working fluids and related materials covers and is designed to s
3、tandardize and consolidate theterminology, nomenclature, and classification of these products.metalworking fluids and related materials.1.2 Metal working Metalworking fluids includes both metal removal and forming fluids. These are the coolants and lubricantsassociated with both types of processes.1
4、.3 This classification implies no evaluation of product quality or suitability for a given metalworking operation.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.2. Terminology2.1 Definitions of Terms Specific to This Stan

It includes both man-made andnaturally occurring liquids.
11、2.1.10 vitreous, adjhaving the appearance and properties of a glass; that is, a hard, amorphous, brittle structure.3. Significance and Use3.1 Metal working Metalworking may be divided into two general types of processes, metal deformation (such as rolling) andmetal removal or cutting.(such as grindi
12、ng or cutting). This classification lists the various types of fluid and non-fluid materials1 This classification is under the jurisdiction of ASTM Committee D02 on Petroleum Products and Lubricants and is the direct responsibility of Subcommittee D02.L0.04on Metal Deformation Fluids and Lubricants.
