4.32 The requalification of cleanrooms and clean air equipment should be carried out periodically following defined procedures. The requalification should include at a minimum the following:
洁净室和洁净空气设备应按照规定的程序定期进行再确认。再确认至少应包括以下内容:
l Cleanroom classification (total particle concentration).
l 洁净室级别确认(总粒子浓度)
l Integrity test of final filters.
l 终端过滤器完整性测试
l Airflow volume measurement.
l 风量测试
l Verification of air pressure difference between rooms.
l 不同房间之间的压差确认
l Air velocity test (Note: For grade B, C and D the air velocity test should be performed according to a risk assessment documented as part of the CCS. However, it is required for filling zones supplied with unidirectional airflow (e.g. when filling terminally sterilised products or background to grade A and RABS). For grades with non-unidirectional airflow, a measurement of recovery testing should replace velocity testing).
l 风速测试(注:对于B级,C级和D级,应根据CCS中记录的风险评估进行风速测试。但是,对于提供单向流的灌装区域(例如,最终灭菌产品的灌装或A级和RABS背景)是必须的。对于非单向流的洁净区域,可用恢复测试取代风速测试)。
The maximum time interval for requalification of grade A & B areas, is 6 months.
A级和B级区域再确认的最大时间间隔为6个月。
The maximum time interval for requalification of grade C & D areas, is 12 months.
C&D级区域再确认的最大时间间隔为12个月。
