首先:CNC区的定义:CNC是英文 “Controlled Not Classified”的首字母缩写,翻译成中文即“受控但未分级区域”。
参照ISPE的定义:
Controlled Not Classified (CNC)
An area without airborne particle limits, but with filtered ventilation.
更进一步的说明如下(ISPE Baseline Guide, Vol. 3: Sterile Product Manufacturing Facilities (Second Edition)
):
Controlled Not Classified (CNC)
A non-classified room environment where closed processes and their immediate support systems may be located. CNC space is cleanable, access controlled and served with filtered ventilation air; procedural controls and personnel garment upgrades may be applied at the Owner’s discretion. In the biopharmaceutical industry CNC is replacing the term “Gray Space”.
ISPE中对换气次数得描述:15~20 AC/hr for Controlled Not Classified(CNC)spaces
可以看出,CNC区域的硬件有空气处理单元,为该区域提供过滤后的洁净空气;软件方面,要求进出控制、更衣、做清洁。与传统的洁净区相比较,就是无需设定相关的尘埃粒子限度,也不需要进行监测。但是相关的清洁和控制是需要进行的。
举例:意思是出入受控,环境受控,但是不一定要达到洁净级别。比如微生物实验室放置培养箱和试剂菌种的地方。如果与D级区联通,则应按D级区管理。
