What are the testing items and instruments for protective masks?

In addition to medical protective masks and daily protective masks, the masks we come into contact with daily also include disposable protective masks, knitted masks, mask paper and other products. Medical masks can block viruses, so what tests and equipment are required for medical masks?

Medical mask testing items

The testing standard for medical protective masks is GB19083-2010 "Technical Requirements for Medical Protective Masks". The main test items are the breaking strength of the mask belt, surface moisture resistance, filtration efficiency, bacterial filtration efficiency, respiratory resistance, flame retardant performance, damp heat test, high and low temperature test, safety performance, total number of bacteria, coliform bacteria, Pseudomonas aeruginosa, golden yellow Staphylococcus, hemolytic streptococcus, total number of fungal colonies, qualitative detection of fungi, bactericidal performance, antibacterial performance of leaching anti-(inhibition) products, antibacterial performance of non-dissolving anti-(inhibition) products, stability, production environment air , The total number of bacteria on the surface of the workbench and the surface of the worker's hands, ethylene oxide disinfection, pressure steam disinfection, etc.

Medical mask breaking strength test

QINSUN Instruments TSL electronic tensile testing machine is mainly used to test the mechanical properties of medical surgical masks, disposable gloves, protective clothing laces, disposable mask belts and other mechanical properties related to tension, compression, tearing, peeling, deformation and other items. At the same time, it can also perform mechanical properties such as stretching, tearing, elongation, and peeling of plastics, woven bags, non-woven fabrics, plastic films, products, PVC pipes, paper cardboard, woven bags, packing tapes, tapes, adhesives, etc. test.

TSL electronic tensile testing machine (tensile testing machine for medical masks) is mainly used for testing and analyzing the mechanical properties of masks such as stretching, peeling, and tearing, and automatically obtains relevant mechanical test performance parameters. It has fast running speed and friendly interface. Simple operation and other features can meet the test and measurement needs of different materials. Computer control; pull and press two-way test. Imported force sensor; imported servo drive system, pre-tightened lead screw. Stepless speed regulation, speed can be set continuously, software input; electronic limit, no manual adjustment.
