Dry penetration tester is designed to determine the properties of the material on the dry matter in the size of the human body dander.
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.
