The HB 7056.3-2004 Dry-Film lubricant test method, Part 3: Dry-Film lubricant adhesion test method specifies the test method for Dry-Film lubricant adhesion. The standard is mainly used to evaluate the adhesion performance of Dry-Film lubricants on different material surfaces, ensuring that the lubricant can adhere to the surface stably during use, providing the desired lubrication effect. Standardized test methods can quantify the adhesion of Dry-Film lubricants, helping manufacturers and users to select lubricant products suitable for specific applications. This test method is crucial for the quality control of Dry-Film lubricants in industrial production, and is widely used in Machinery, automotive industry, electronic components and other fields to ensure the reliability and performance of the lubrication layer under long-term use.
