Recently, the national standard Code for Construction and Acceptance of Cleanrooms for Pharmaceutical Industry (GB/T 51466-2025), co-compiled by TIANS Group, has been published on the official website of the Ministry of Housing and Urban-Rural Development (www.mohurd.gov.cn). Organized and published by the Institute of Standards and Quotas of the Ministry of Housing and Urban-Rural Development through China Planning Press Co., Ltd., the standard will be officially implemented on September 1, 2025. Ms. Zhou Lanxia, Director and President of the Group and Dean of the Chemical and Pharmaceutical Design Institute; Mr. Pan Houchang, Chief Engineer of the Chemical and Pharmaceutical Design Institute; Mr. Wang Lubo, Deputy Chief Engineer of the Chemical and Pharmaceutical Design Institute; and Mr. Liu Zhefeng, Deputy Chief Engineer of the Process Technology Center, participated in the compilation and review of this standard as contributors and reviewers.

This standard provides comprehensive and detailed regulations for the construction and acceptance of cleanrooms in the pharmaceutical industry, covering aspects such as architectural finishes, purification HVAC, process piping, water supply and drainage, equipment installation, fire protection and safety facilities, electrical systems, instrumentation, and communication. The formal implementation of the standard will promote the standardization of construction and acceptance practices in the pharmaceutical industry, ensure that facility facilities meet pharmaceutical production requirements, safeguard drug quality and safety, and advance the technological level and healthy development of the pharmaceutical industry.
