Scope

Scope: This standard specifies the terms and definitions, product classification and codes, technical requirements and test methods, inspection rules and marking, packaging, transportation and storage, and delivery note content for graphene-enhanced extreme pressure lithium-based lubricating grease (which may be referred to as graphene-enhanced lubricating grease) used in construction machinery. The products specified in this standard are suitable for lubricating components of construction machinery under low-speed high-load, high-impact friction, and operating temperatures ranging from -20°C to 150°C. Equipment in fields such as agricultural machinery, defense equipment, and the steel industry can refer to this standard for use. Main technical content: The standards applicable to extreme pressure lithium-based lubricating grease include JCMAS P 040-2004 "Lubricating Grease for Construction Machinery" issued by the Japan Construction Machinery Association (JCMA) and GB/T7323-2008 "Extreme Pressure Lithium-Based Lubricating Grease" issued by China. Compared with JCMAS P 040-2004 and GB/T7323-2008, this standard establishes the following technical requirements: - Adding a grading system for extreme pressure anti-wear performance to provide a basis for selecting lubricating grease for specific applications; - Introducing the wheel loader lifting test (WL-L) method (patented technology) to simulate and evaluate the extreme pressure anti-wear performance of lubricating grease in actual application scenarios; - Establishing technical specifications for No. 3 lubricating grease to meet the needs of tropical regions or high-temperature environments; - Adding a quality stability data table (Appendix B) to inspect the quality stability and reliability of lubricating grease and provide data accumulation for continuous improvement of new products; - Raising the limit value of drop point to 200°C.
