Microbial Ranking of Porous Packaging Materials ASTM F1608

Microbial Ranking of Porous Packaging Materials ASTM F1608

ASTM F1608 is a microbial integrity test and is used for determining the presence of air-borne bacteria through porous materials used in the packaging of sterile medical devices. The test result is reported in terms of the log reduction value (LRV) for each test material.

    Scope:

    ASTM F1608 is used for determining the presence of air-borne bacteria through porous materials used in medical packaging. The outer packaging is exposed to various types of microorganisms during the distribution process. Exposure is influenced by different factors such as shipping methods, storage conditions, and geographic location. 

    Test Procedure:

    For the ASTM F1608 test, the samples of porous material are placed in an aerosol of Bacillus atrophaeus spores inside an exposure chamber. The spores that pass via the porous sample are collected on membrane filters and enumerated. Finally, the Log Reduction Value (LRV) is determined by comparing the logarithm of the number of spores passing through the porous material with the logarithm of the microbial challenge.

    Sample size:

    The samples are used as stated by ASTM F1608 guidelines.
