Static electricity attraction can cause pollutants to accumulate, pollute the clean environment, and affect Affects product quality and personnel health; electrostatic discharge can cause harm to electrostatic sensitive equipment and products in clean environments, and also cause electrical safety and fire protection. Improper static control measures will not only affect the airflow organization and cleanliness of the clean room, but also affect the electrical and Fire safety. This document specifies the static control measures that are consistent with the design and operation characteristics of clean rooms, based on the characteristics of static sources and hazards in clean rooms. Technical requirements to control the effects of static electricity in clean rooms. Cleanrooms and related controlled environments Technical requirements for static control1 ScopeThis document provides the sources and hazards of static electricity in clean rooms and related controlled environments, and specifies the applicable Technical requirements for static control. This document applies to the control of static electricity in cleanrooms and related controlled environments.2 Normative referencesThe contents of the following documents constitute essential clauses of this document through normative references in this document.
