2026年5月，ISO 14644-14:2026正式发布。该标准提供了一套标准化的测试方法，用于评估设备是否适合在特定洁净度级别的洁净室中使用。测试流程包括：视觉检查、高粒子浓度位置识别、代表性运行模式下的采样测试和数据判定。该标准为洁净室设备的准入管理提供了量化的粒子排放评估依据，而不仅依赖于供应商的声明。 Disclaimer: This article is for informational purposes only
was known as the "Particle Ghost." As the lead quality engineer at Apex Microchips, his job was to ensure that not a single speck of dust—nothing larger than a fraction of a micron—interfered with the delicate lithography of their newest processors.
The overarching purpose of ISO 14644-3 is to establish unified, reliable, and repeatable testing frameworks. Cleanrooms rely on a precise balance of filtration, airflow, and pressure differentials to exclude external pollutants and control internal contamination. The standard outlines tests that evaluate these physical variables. The installation is complete, with all services connected
The standard consists of several parts, with Part 1 providing an overview of the cleanroom concept, the importance of contamination control, and the basic requirements for cleanroom design and operation. The document also provides guidelines for the assessment and control of airborne particulate contamination, as well as the evaluation of cleanroom performance.
