摘　　要：高效空气过滤器现场扫描检漏测试是保证洁净室工程质量的必要措施之一,但在实际工程测试时常遇到将高效空气过滤器边框及安装框架处含尘浓度偏高误判为存在漏点的问题,介绍了IEST给出的相关测试方法及部分洁净室施工人员采取的非扫描检漏测试方法,通过理论分析及大量实验研究,提出了科学合理的高效空气过滤器扫描检漏测试方法。In situ scanning leak test for installed high efficiency particulate air （HEPA） filters is a necessary step to guarantee the quality of clean rooms. However, because particle concentration of dead-air spaces, such as where near the filter frame and support structure, is always high in the actual HEPA filter, leaks in dead-air spaces are mistakenly considered to exist. Presents two different relevant leak test methods, and gives a new reasonable method based on theoretical analysis and experimental research.
