Can anyone share their program for in use test of solids in multiple use packs (ie HDPE bottles containing 30 units)- there is no clear guidance on how to perform the test and I am looking for some sort of industry standard companies are using- for example remove 1 tablet a day for 20 days (leaving 10 tablets in the bottle) , store for an additional 10 days opening the bottle once a day- (total test time 30 days) and then test the remaining samples or remove 1 tablet a day from bottle a and move into bottle b (empty) until all 30 units have been moved from bottle a to bottle b- perform the testing on the units in bottle b
