Standard Test Method for Adhesion of Solid Film Lubricants

Standard Test Method for Adhesion of Solid Film Lubricants

SIGNIFICANCE AND USE
Effective solid film lubricant coatings must adhere to surfaces to provide adequate lubrication in applications with restricted access where fluid lubricants cannot easily be replenished. Loss of coating adhesion results in metal to metal contact causing significant wear of contacting surfaces. Adhesion is critical to the performance of the solid film lubricant. Examples of solid film lubricant applications include fasteners, bearings and sliding members in automotive, aircraft, and aerospace hardware.
This test method is intended to determine the adhesion of solid film lubricant coatings when submitted to contact with water and other fluids. Results of this test provide an indication of the suitability of the lubricant coating in applications where contact with water or other fluids is likely.
SCOPE
1.1 This test method covers the measurement of the adhesion characteristics of dry solid film lubricants.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information only.
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.

ASTM D8112-24(Guide)
Standard Guide for Obtaining In-Service Samples of Turbine Operation Related Lubricating Fluid

SIGNIFICANCE AND USE
5.1 Fluid analysis is one of the pillars in determining fluid and equipment conditions. The results of fluid analysis are used for planning corrective maintenance activities, if required.  
5.2 The objective of a proper fluid sampling process is to obtain a representative fluid sample from critical location(s) that can provide information on both the equipment and the condition of the lubricant or hydraulic fluid.  
5.3 The additional objective is to reduce the probability of outside contamination of the system and the fluid sample during the sampling process.  
5.4 The intent of this guide is to help users in obtaining representative and repeatable fluid samples in a safe manner while preventing system and fluid sample contamination.
SCOPE
1.1 This guide is applicable for collecting representative fluid samples for the effective condition monitoring of steam and gas turbine lubrication and generator cooling gas sealing systems in the power generation industry. In addition, this guide is also applicable for collecting representative samples from power generation auxiliary equipment including hydraulic systems.
