Standard Test Method for Iron Chip Corrosion for Water–Miscible Metalworking Fluids
Standard Test Method for Iron Chip Corrosion for Water–Miscible Metalworking Fluids
SIGNIFICANCE AND USE 5.1 The results obtained by this test are a useful guideline in determining the ability of water-miscible metalworking fluids to prevent or minimize rust under specific conditions. There is usually a relationship between the results of this test and a similar ability of the subject coolant to prevent rust on nested parts or in drilled holes containing chips, etc. It must be understood, however, that conditions, metal types, etc. found in practice will not correlate quantitatively with these controlled laboratory conditions. The procedure may not be able to differentiate between two products with poor rust control due to the wide spacing between test dilutions. SCOPE 1.1 This test method covers evaluation of the ferrous corrosion control characteristics of water–miscible metalworking fluids. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.2.1 Exception—Note 1 contains inch-pound units since the drill sizes and feed rates do not have readily available metric equivalents. 1.2.2 Exception—U.S. Standard sieve sizes include mesh values. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
ASTM D4627-22: Standard Test Method for Iron Chip Corrosion for Water–Miscible Metalworking Fluids provides a laboratory method for evaluating the ferrous corrosion control characteristics of water–miscible metalworking fluids. The main objective is to assess the capability of these fluids to prevent or minimize rust formation on ferrous parts, particularly under conditions simulating those encountered in machining environments.
This standard is widely recognized by manufacturers and users of metalworking fluids, quality assurance professionals, and laboratory technicians seeking a reliable guideline for fluid selection and performance verification regarding corrosion prevention.
