Dry Microbial Penetration Resistance Tester - China

Dry Microbial Penetration Resistance Tester is designed to determine determine the penetration resistance of material to bacterial on dry particulates at a size range of human dandruff.

The resistance to dry microbial penetration test (ISO 22612) evaluates resistance characteristics of protective equipment to dry bacteria-carrying particles.

Testing is most often performed on equipment such as surgical gowns, drapes, and clean air suits when used as medical devices.

This test is part of a test suite required by the EN 13795 guidance, which determines performance requirements and performance levels for gowns, drapes, and clean air suits when used as medical devices.

It is also included in the test suite required by EN 14126, for personal protective equipment.

Testing in compliance to EN 13795 is part of following the European Union Medical Device Directive 93/42/EEC, and is important when seeking a CE mark for products marketed in Europe.

Nelson Laboratories personnel are experts in barrier testing, and we offer a one-stop shop for barrier tests required for marketing gowns and drapes in both the US and Europe.

Standards:

ISO 22612; YY / T 0506.5-2009 Test principle:

When testing, the samples were seperately fixed on a container.

In these containers, five containers carrying the bacillus subtilis and 1 container carrying uncontaminated talc powder used as control.

Insert 1 petri dish at the bottom of each container and beneathe the bottom of the specimen.

The supporting vessel's equipment is oscillated by a gas ball type oscillator, and all of the talcum powder passing through the sample falls onto the petri dish.

Remove the petri dish for culture.

The experiment results were evaluated by counting the colonies.

Scope of application:

Dry microbial penetration resistance performance tester is professionaly used to determine the bacterial penetration resistance performance of materials to dry particulates in the size range of human body dandruff.

Whenn testing, the samples were fixed on a container respectively.

In these containers, five containers containing subtilisin talc, one container added with Not stained talcum powder was used as a control.

A Petri dish was inserted at the bottom of each container at a distance from the bottom of the timer.

The equipment supporting the container is oscillated by a Gas ball oscillator, and all the talc penetrating the sample Falled on the culture dish, cultured without the culture vessel.

The test results were evaluated by counting the growing colonies.
