我国牵头，正式发布！

Core Viewpoint - The International Organization for Standardization (ISO) has officially released a new international standard for sliding bearings, led by China and involving experts from seven other countries, addressing the long-standing issue of comparability in testing data within the industry [1]. Group 1: Standard Development - The new standard is titled "Sliding Bearings - Testing of the Tribological Properties of Bearing Materials - Part 1: Testing of Bearing Alloy Materials" [1]. - The standard focuses on boundary lubrication conditions, which are critical for the performance of sliding bearings [1]. - It incorporates cutting-edge research findings and industrial practices, validated through thousands of tests and data analyses [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 establishment of a high reproducibility international testing benchmark aims to systematically resolve the industry's long-standing pain point of insufficient comparability in test results globally [1]. - The standard details sample preparation, unifies testing parameters, and enforces strict requirements for surface roughness and environmental conditions [1].
