请仔细阅读以下指南!! 有很明确的解释!!
Grade A air supply is interpreted as follows:
Qualification requirements:
• Qualification is done only at at rest conditions: For the crimp-capping machine the at-rest state is achieved when the air supply is switched on, the crimp capping machine is operating (feeding of vials and crimp caps is not considered necessary) and there is no interference by operators. For the conveyor tunnel for liquid products the at-rest state is achieved when the air supply is switched on, the conveyor belt is switched on and there is no interference by operators.
• Non-viable particles should be measured and are expected to meet grade A requirements. The probe should be located underneath the filter.
• Smoke studies should be performed. Unidirectional air flow is not required, however, efficient protection of the vials should be demonstrated.
• Limits for air velocity should be in place and justified.
Monitoring requirements:
• Monitoring requirements for non-viable particles and microbiological contamination should be defined by the company following a risk assessment. |
