Cleanrooms and related controlled environments are used to control indoor pollution to an appropriate level to complete pollution-sensitive activities, such as electronics, aviation, The environmental conditions necessary for production and scientific research in industries such as aerospace, food, medicine, and medical care are difficult to build, require complex technology, consume high energy, and require high investment. This revision proposes the basic requirements that clean rooms and related controlled environments should meet, the main contents of performance and rationality evaluation, and the evaluation Conclusions and grade requirements to ensure that clean rooms and related controlled environments are designed reasonably, operate reliably, and have advanced technology on the basis of safety and compliance. It can meet the technological and usage requirements of production and scientific research, while being economical, applicable, green and energy-saving. Cleanrooms and related controlled environments Performance and rationality evaluation

1 Scope

China's national standard for evaluating the performance and the rationality of cleanrooms and associated controlled environments. It specifies the general requirements, the content of the evaluation, the evaluation conclusion and grading, and the evaluation report. Cleanroom standards mostly answer one question: how clean is it. The classification standards count particles and assign a class, and a room either meets its class or does not. This document asks a second question that the classification standards do not: is the installation reasonable. A cleanroom that meets its particle class while consuming three times the energy it needs, or while being impossible to clean, or while depending on an air change rate chosen by copying another project, has passed its classification and failed as an engineering solution. Cleanrooms are among the most energy-intensive buildings there are - the air handling runs continuously and moves enormous volumes through high efficiency filters - and the specified cleanliness class, once chosen, drives that cost for the life of the facility. So the evaluation covers the performance against the requirements and the rationality of how it is achieved: whether the class specified is the class the process needs, whether the airflow arrangement suits the activity, whether the pressure regime does what it is supposed to, whether the monitoring measures the right things in the right places, and whether the energy consumed is proportionate. The 2024 revision restructures the document around that purpose. It replaces the linkage between evaluation and project progress with general requirements, revises the evaluation content, and adds two chapters that the 2012 edition did not have: an evaluation conclusion with grades, and an evaluation report. Issued and in force since 23 August 2024, it replaces GB/T 29469-2012.

This document specifies the general requirements for the performance and rationality evaluation of cleanrooms and related controlled environments, as well as the evaluation content, evaluation conclusions and Grade and evaluation report. This document is applicable to the performance and rationality evaluation of production and scientific research clean rooms and related controlled environments in various industries.
