Abstract

The National Control Laboratory of the RIVM has performed a series of tests on different wrapping materials to demonstrate that a proposed test for dry bacteria tightness can be used for all different wrapping materials and methods. The test has been used on paper, textile, non-woven and containers showing that these wrapping materials/methods can be compared objectively on their performance in actual practice. The method still needs fine-tuning but already shows big advantages over other already existing testmethods which are in general based on a product type and/or non performance related criteria. The data in the report are the complete actual data, thus allowing CEN TC 102 WG4 to form its own opinion about this test procedures.
