Products and processes in industries such as pharmaceuticals, medical devices, food, and healthcare benefit from the control of air pollution. This document does not contain the testing procedures for all clean room parameters. GB/T 25915.1 provides the classification of air cleanliness by particles, etc. GB/T 25915.12 provides the technical requirements for monitoring the concentration of nanoparticles in the air. Cleanrooms and clean areas for specific processes and the testing procedures and instruments used for related parameters are included in other documents prepared by ISO /TC209 Discussion [e.g. microbial control and detection procedures (GB/T 25916 series), clean room functional testing (GB/T 25915.4), and isolation Device testing (GB/T 25915.7)]. In addition, other applicable standards can also be considered in the clean room testing activities. The level of air cleanliness can be classified by GB/T 25915.8 (classification of air cleanliness by chemical concentration), GB/T 25915.9 (classification by particle concentration). The surface cleanliness level is determined by GB/T 25915.10 (surface cleanliness level according to chemical concentration).
