8.92 In a redundant filtration system (where a second redundant sterilising grade filter is present as a backup but the
sterilising process is validated as only requiring one filter), post-use integrity test of the primary sterilising grade filter
should be performed and if demonstrated to be integral, then a post- use integrity test of the redundant (backup) filter is not
necessary. However, in the event of a failure of the post-use integrity test on the primary filter, post-use integrity test on the
secondary (redundant) filter should be performed, in conjunction with an investigation and risk assessment to determine the
reason for the primary filter test failure. |
