法规要求只做一个就可以了,但是行业里面我见到目前大家都是两个都测得
8.9392 In a redundant filtration system (where a second redundant sterilising grade filter is
present as a backup but the sterilizing sterilising process is validated as only requiring one
filter), post-use integrity test of the primary sterilizing sterilising grade filter should be
performed and if demonstrated to be integral, then a post-use integrity test of the
secondary redundant(backup) filter is not necessary. However, in the event of a failure of the
post-use integrity test on the primary filter, a risk assessment should be carried out to
determine the acceptability of performing a post-use integrity test on the secondary
(redundant) filter should be performed, in conjunction with an investigation and risk
assessment for to determine the reason for the primary filter test failure.
在冗余过滤系统中(存在备用的第二个冗余除菌级别过滤器,但除菌工艺验证仅要求一个过
滤器),应执行主除菌过滤器使用后的完整性测试,如果主除菌级别过滤器被证明是完整的,
则不需要对第二个冗余过滤器进行使用后的完整性测试。然而,如果主过滤器使用后的完整
性测试失败,则应针对第二个冗余过滤器开展使用后完整性测试,同时应针对主过滤器的完
整性测试失败开展根本原因调查和风险评估。 |
