Standard Test Method for Deposition Tendencies of Liquids in Thin Films and Vapors

SCOPE
1.1 This test method covers the determination of the tendency of liquids in thin films and of vapors to form deposits on metal surfaces. The test method applies to both petroleum-based and synthetic lubricants, hydraulic fluids, heat-transfer fluids, and related materials.
1.2 The values stated in SI units are to be regarded as the standard. In cases where materials, products, or equipment are available in inch-pound units only, SI units are omitted.  
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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 7.
