(Test Method)Standard Test Method for Misting Properties of Lubricating Fluids
Standard Test Method for Misting Properties of Lubricating Fluids
SIGNIFICANCE AND USE
5.1 This test provides a guide for evaluating the misting characteristics of oils for use in industrial mist lubrication systems. The degree of correlation between this test and service performance has not been fully determined.
SCOPE
1.1 This test method covers the determination of the misting characteristics of lubricating fluids.
Note 1: This test method should not be used to evaluate fluids containing solid additives such as graphite.
1.2 The values stated in SI units are to be regarded as standard.
1.2.1 Inch-pound units are used to describe the various tube fittings shown in Fig. 1.
1.2.2 Inch-pound thread is shown in Fig. 2.
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. For specific warning statements, see Sections 7 and 8.
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.
