中国牵头的滑动轴承国际标准发布

Core Viewpoint - The International Organization for Standardization (ISO) has officially released a new international standard for testing the tribological properties of bearing materials, led by China with contributions from experts from seven other countries, addressing a critical need for standardized testing in the sliding bearing industry [1] Group 1: Standard Development - The new standard focuses on boundary lubrication conditions, incorporating cutting-edge research and industrial practices [1] - It was developed through extensive testing, including thousands of experiments and data analyses, to create a highly reproducible international testing benchmark [1] - The standard aims to resolve the long-standing issue of comparability in test results across the industry, which has hindered development [1] Group 2: Industry Impact - Sliding bearings are essential components in various high-end equipment, including heavy machinery, precision machine tools, efficient motors, wind turbines, and high-speed trains, directly affecting their reliability, efficiency, and lifespan [1] - The evaluation system established by the new standard is more scientific and closely aligned with actual complex working conditions, which is significant for enhancing the research and quality control of modern alloy materials [1]
