1、美国药典35版<1116> :for air changes per hour and air velocities are not included in ISO 14644, nor were they included in Federal Standard 209E. Typically, ISO Class 8/Class 100,000 rooms are designed to provide a minimum of 20 air changes per hour; ISO Class 7/Class 10,000 rooms are designed to provide more than 50 air changes per hour; and ISO Class 5/Class 100 clean rooms provide more than 100 air changes per hour.
2、ISO 8级(即十万级)洁净室换气次数在设计时的要求是最少20次每小时,ISO 7级(即万级)最少50次每小时,ISO 5级(即百级)最少100次每小时。
3、你是想说,换气次数意义不大?还是质疑法规的权威性?其实对于制造公司来说执行,当然你有时间去研究和验证也行,但在你对应的药政中有要求,你就必须要达到,没有,当然你验证,采用验证结果来指导日常,也未尝不可 |
