Recently, Ding ZhiJie, vice president and chief designer of TIANS Group and Qiu JiFu, chief engineer of Shanghai Design and Research Institute participated in the "clean room and related controlled environment" drafted by the national clean room and related controlled environment Standardization Technical Committee of China Standardization Association Part 1: classification of air cleanliness according to particle concentration, and revision of two standards of clean room and relevant controlled environment Part 2: evidence of air cleanliness in clean room provided by particle concentration monitoring, so as to promote the industry to a higher level.

    The two revised standards drafted by the National Technical Committee for the standardization of clean rooms and related controlled environments will realize the reasonable division of controlled environment, determine the clean rooms and related controlled environment grades with different working objectives, and help to reduce unnecessary construction costs and energy consumption. At the same time, according to the classification requirements of the development of international clean rooms and related controlled environment, a more continuous statistical method is adopted for the selection and quantity of sampling points, which has a good guidance and practical value for the super large clean rooms and related controlled environment in China. The clean room and relevant controlled environment will control the air suspended particles at an appropriate level to adapt to the polluted and sensitive working environment, which will directly benefit the products and processes of aerospace, microelectronics, pharmaceutical, medical equipment, food, medical and health industries from the control of suspended pollutants.

    As a leader in EPC of domestic pharmaceutical and environmental protection projects, TIANS Group, relying on its rich experience in EPC project implementation and many well-known experts and scholars in the industry, is at the leading level in technology by virtue of the complete closed-loop service of engineering design, electromechanical engineering, clean Engineering, automatic control engineering, environmental protection engineering and operation and maintenance industry chain. In the future, the group will continue to send first-class industry experts to actively participate in the standardization work of the industry and realize the technical guarantee for the development of the industry.

    Standards are called "laws" to regulate market economy. It is an important national technical and economic policy to actively promote standardization. With the continuous improvement of China's economic quality, a sound and perfect standard system is an important guarantee to promote the development of the industry, as well as an important basis for measuring inspection and standard certification.
