Recently, two national standards, clean rooms and related controlled environments Part 1: classification of air cleanliness according to particle concentration and clean rooms and related controlled environments Part 2: providing evidence of air cleanliness in clean rooms by particle concentration monitoring, drafted by TIANS Group, will be officially implemented. These two national standards are under the jurisdiction and implementation of the national clean room and related controlled environment Standardization Technical Committee, and managed by the National Standardization Management Committee. They have been issued on August 20, 2021 and will be officially implemented on March 1, 2022.

The two national standards drafted by TIANS will be officially implemented soon

The formulation of this standard specifies the classification of air cleanliness levels in clean rooms, clean areas and isolation devices described in GB / T 25915.7 according to the concentration of suspended particles in the air, and forms the minimum requirements for the performance monitoring plan of clean rooms or clean areas. In the process of formulating the standard, through a large number of facility configuration, monitoring, detection and verification, it is proved that it can meet the monitoring technology and instrument requirements of the standard. On the one hand, it guides the relevant research and development direction of the industry, on the other hand, it shows that it has the foundation to provide an ultra clean and controlled environment for domestic R & D and industry.

With the rapid development of modern industry and cutting-edge technology, clean rooms and clean technology are constantly updated. In particular, scientific experiments and high-tech production processes represented by biomedicine, microelectronics and high-precision equipment manufacturing put forward higher standards for the precision, miniaturization, high purity, high quality and high reliability of enterprise product finishing. As a national specialized new giant enterprise and a national high-tech enterprise, TIANS Group has always adhered to the guidance of science and technology, served more than 50 top 100 Chinese pharmaceutical enterprises, and designed and built a number of industry model projects in many fields, such as biomedicine, chemical medicine, environmental protection engineering, automation and information engineering.

In the future, TIANS will continue to take science and technology as the guide and technology as the guarantee, deeply participate in the construction of framework standardization, provide more scientific support for the design and construction of clean facilities, and continue to build more high-quality projects, so as to achieve win-win progress with the industry.
