Standards compliant:
ISO 22612; YY / T 0506.5-2009
Test principle:
Test, the samples were fixed on a container. Of these containers, five containers containing Bacillus subtilis powder and one container were added as uncontrolled talc as a control. A petri dish was inserted at the bottom of each container at a distance from the bottom of the container. The equipment supporting the vessel is oscillated by a gas balloon, and the talc penetrating the sample is all dropped onto the culture dish to remove the culture of the culture dish. The experimental results were evaluated by counting the growing 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.
on 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 experimental results were evaluated by counting the growing colonies.
