ISO 14644-5:2004规定了洁净室操作的基本要求。它适用于那些计划使用和运营洁净室的人。ISO 14644本部分未考虑与污染控制无直接关系的安全方面，必须遵守国家和地方安全法规。本文件考虑了用于生产各类产品的各类洁净室。因此，它的应用范围很广，没有针对个别行业的具体要求。ISO 14644本部分未详细介绍洁净室内常规监测的方法和程序，但应参考ISO 14644-2和ISO 14644-3监测颗粒物，以及ISO 14698- 1和ISO 14698-2，用于监测微生物。

ISO 14644-5:2004 specifies basic requirements for cleanroom operations. It is intended for those planning to use and operate a cleanroom. Aspects of safety that have no direct bearing on contamination control are not considered in this part of ISO 14644 and national and local safety regulations must be observed. This document considers all classes of cleanrooms used to produce all types of products. Therefore, it is broad in application and does not address specific requirements for individual industries. Methods and programmes for routine monitoring within cleanrooms are not covered in detail in this part of ISO 14644 but reference should be made to ISO 14644-2 and ISO 14644-3 for monitoring particles, and ISO 14698-1 and ISO 14698-2 for monitoring micro-organisms.
