Introduction

GB/T 36306—2024 Standard Overview

The National Standard of the People's Republic of China GB/T 36306—2024 "Technical Requirements for Air Chemical Pollution Control in Clean Rooms and Related Controlled Environments" was issued in 2024, replacing the old version GB/T 36306—2018. The new standard comprehensively revised and optimized the air chemical pollutant control technology in clean rooms, aiming to meet the needs of the development of high-tech industries and improve the air quality of clean room environments.

Analysis of key changes in the standard

Old version content	New version content	Change description
Scope of application is limited to clean rooms	Covering clean rooms and related controlled environments	The scope of application of the standard has been expanded
Pollutants are not classified in detail	Air cleanliness (ACC) levels are divided according to chemical concentrations	Pollution classification methods have been added

Pollution sources and control technologies

Pollution source analysis

Pollutants in clean rooms mainly come from:

• Chemical pollutants in the outdoor atmosphere, such as sulfur oxides, nitrogen oxides, etc.
• Activities of indoor workers, including chemicals released from sweat and protective equipment.

Control technology

The new standard recommends the use of ion chromatography (IC) and inductively coupled plasma-mass spectrometry (ICP-MS) for pollutant detection to ensure the accuracy and reliability of the data.

Implementation recommendations

• In the early stages of clean room construction, low-volatile materials should be given priority, and chemical pollutant release tests should be conducted.
• Ventilation should be strengthened during the construction phase, especially when using epoxy coatings and fireproof materials.
