Microbial Ranking, ASTM F1608

This test procedure is used to evaluate porous materials intended for use in packaging sterile medical devices. This test employs a low flow rate, extended exposure time, and increased challenge level, which allows testing of materials with high differential pressure values. This test method is not intended to predict the performance of a given material in a specific sterile packaging application.

The procedure consists of subjecting samples to an aerosol of Bacillus atrophaeus spores at a concentration of about 1 x 106 for 15 minutes within an exposure chamber. Spores passing through the porous material are collected on membrane filters and enumerated. This procedure is designed to comply with ASTM F1608 test method.

Please see our Packaging Validation matrix for more information.
