ISO 22612 Dry Microbial Penetration Resistance tester For Protective Clothing

       Dry microbial penetration resistance 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.

    Dry microbial penetration resistance tester is used to evaluate 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.

Multi-Functional Scratch tester For automotive interior materials

          Multi-Functional Scratch tester is applicable to all types of wiping performance test of automotive interior materials; test equipment integrated three domestic standards (fingers scraping method, a hundred grid method, and plastic scraping finger scraping method).         Scratch tester is an electronic instrument capable of measuring critical load, adhesion, scratch resistance and bond strength for a wide range of surfaces. Scratch tester measures the scratch resistance of a sliding and moving surface in the relative motion to a stylus. The stylus is forced/pressed against the moving surface with precise controlled force which is normal to the surface and tangential force at the contact has to be measured.         Scratch tester can be utilized for all type of industrial coating from the plasma layers used in semiconductor and optical technology used in decorative coatings used for automotive and consum...

Reveal the standards for textile breathability testing and let you understand it in seconds!

 Reveal the standards for textile breathability testing and let you understand it in seconds! Breathability testing is a measure of how much gas can pass through a textile. However, there is no single "optimal" air permeability value, as it depends on the specific circumstances in which the textile is used. For example, if it is used to make sportswear, it is hoped that it has good breathability; if it is used to make insulating clothes or warm clothes, it is hoped that it can block the cold well. Therefore, when testing the air permeability of textiles, the purpose of using the textile must be clearly understood in order to obtain reasonable values. In order to accurately and quickly test the true breathability performance of a sample, specially designed and developed instruments must be used. Testing methods generally include: fabric thickness (Thickness), fabric density (Density), fabric water absorption rate (Water Absorption Rate), evaporation and mass transfer (Moistur...

Test Methods of Universal Pilling Assessment Viewer (PAV)

Universal Pilling Assessment Viewer enables fabric to be assessed while still mounted on a Martindale head. The Pilling Assessment Viewer (PAV) for the textile market has been developed with the help of a major textile company in accordance to BN EN ISO 12945 standards incorporating all 3 parts and adopting the following test methods: Part 1: ICI Pilling box method (BS 5811) Part 2: Modified Martindale method (SN 198 525) Part 3: Atlas random tumble method (ASTM D 3512-96) It uses D65 Artificial Daylight (with CWF optionally available), as specified by many retailers. Other test methods can also be viewed, including those specified by major retailers. Other results of test methods that can be viewed include: BS 5811:1986 Determination of resistance to pilling and change of appearance of fabrics. ICI modified pill box for snagging Fleece appearance and surface change after washing Other test methods as specified by several major retail outlet. To optimize c...
