 All we know the medical face mask has to test the Breathability(differential pressure), which is the delta P value. The standard of EN14683 required this device which measures the differential pressure to draw air through a measured surface area at a constant air flow rate is used to measure the air exchange pressure of the medical face mask material. A water-filled(or digital) differential manometer is used to measure the differential pressure. A mass flow meter is used for measurement of the airflow. However, the standard of EN14683:2004 has been replaced by EN14683:2019 version, for air flow leakage issue, the standard propose higher requests for assuring testing result accuracy. Let us see which requests has been highlighted by EN14683:2019: 1. The internal diameter of the top holder and the bottom holder in the contact area with the filter material shall be (25+/-1)mm. 2. The seal of the top and bottom holder onto the filter material shall consist of a metal-metal contact. A ...

       A surgical face mask is also known as a procedure mask and purposely to be worn by health care professionals during operation procedures. It helps to catch the bacteria shed in liquid droplets and aerosols from the wearer's mouth and nose.      For the Surgical masks manufacturers ,we need some test machine to measure and control the quality. Because every country has own test standards for the measurement of Surgical masks. the list you need is as follows:          Medical Face Mask Fire Resistance Tester  is mainly used to test the flame retardant performance of medical masks. The combustion performance of the mask is measured through a head mold wearing a mask de-vice to contact with the flame at a certain linear speed.      Medical masks synthetic blood penetration tester  is used to determine the resistance of medical protective masks to penetration by synthetic blood at different test...

      The current epidemic of new coronavirus pneumonia is still spreading. China's mask production capacity has been stepped up to recover, but in the face of a huge gap, it is still in short supply. China has also begun to encourage qualified enterprises to switch to production masks, and many domestic companies have responded to the call to switch to production masks.     How do you know if a mask is protective? I believe that every newly converted mask manufacturer wants to know. The following will give you the answer:     In each country, there are relevant mask standards to control the masks quality, thereby effectively helping the masks to be sold domestically or externally. Specific test items are specified within specific standards, and each test item specifies specific test methods and parameter requirements. Once the standards are determined, you know which items need to be tested? What instruments are used for testing?   Just lik...

       Mask is a kind of sanitary products, generally refers to wear in the mouth and nose position used to filter the air into the mouth and nose, in order to block harmful gas, smell, droplets in and out of the wearer's mouth and nose appliances, made of non-woven cloth.Masks have a certain filtering effect on the air into the lungs, in the respiratory tract infection epidemic, dust and other pollution in the environment, wearing masks has a very good effect.                  Masks can be divided into the following categories according to the nature of use: Civil daily protective mask: it is mainly used for filtering out particulate matter in the air pollution environment in daily life.According to its protection level can be subdivided into: anti-haze mask and cotton mask two types.Anti-haze mask is used to effectively filter PM2.5 in the haze weather, its main characteristics are good filtering performance,...

     Surgical face masks are made with non-woven fabric, which has better bacteria filtration and air permeability while remaining less slippery than woven cloth. The material most commonly used to make them is polypropylene, either 20 or 25 grams per square meter (gsm) in density. Masks can also be made of polystyrene, polycarbonate, polyethylene, or polyester.     There are many kinds of test for surgical mask manufacturing .qinsun-lab is a manufacturer who has all the tester for surgical mask. such as :   F l a mmability test ： Medical Face Mask Fire Resistance Tester ;   B reathing resistance test: Medical Face Mask Air Exchange Pressure Difference Tester ; Splash resistance test : Medical Face Mask Synthetic Blood Penetration Resistance Tester Tensile Test: Mask Tensile Testing Machine Particle Filtration Efficiency test : G506 Mask Automatic Filter Performance Tester   Bacteria filtration efficiency in vitro (BFE) test : ...

     Surgical masks are typically used by surgeons to protect their patients from their mouth-borne germs —  but “those masks don't work to prevent inhaling diseases.The masks, which cover the nose and mouth, are often made from a flimsy material and aren’t fitted to the face. In other words, spaces and gaps can form around the cheeks and edges of the mouth, making it easy for air to move in and out.      A more protective mask, known as an N95 respirator, may be more effective, said Schaffner.  But, he noted, a non-medical professional using this mask is likely not using it correctly, doing little to prevent the spread of illness or inhaling a disease.   Certainly ,all the masks must do the test items what the masks test standards specified.each country has its own test standards for mask.there is a list for masks manufacturers to refer to: Air Flow Resistance Tester; Mask Combustion Tester; Medical Face Mask Diff...

   Shrinkage rate refers to the percentage that fabrics’ size presents shrink when washed or soaked, which is also an indicator of measuring the degree of fabric shrinkage. The level of fabric shrinkage rate is one of the criteria to measure product quality.         Fabric shrinkage can cause problems in two main areas: garment manufacturing and subsequent laundering by the ultimate customer. in order to make sure the product quality , the shrinkage test is necessary for each textile manufacturer.   The general procedures for preparing and marking out of samples are given in the British Standard. For critical work the recommended sample size is 500mm X 500mm and for routine work a minimum sample size of 300mm X 300mm is considered as sufficient. The samples are marked with three sets of marks in each direction, a minimum of 350mm apart and at least 50mm from all edges as shown in Figure. In the case of the smaller sample the marks are made...

    Textile Test Instrument Manufacturer -Qinsunlab :   Hydrostatic Head Tester is designed to determine the waterproof property of outdoor wears, umbrella, and waterproof fabric. It is also used to test the resistance of permeability of synthetic blood for materials used in protective clothing.     Hydrostatic head or sometimes just is an outdoor industry standard way of measuring how much force it takes to force water through a piece of fabric.     The way that it is measured is by clamping a piece of fabric over the bottom of the tube and slowly filling the tube with water.    The hydrostatic head measurement just refers to how high the water got up to tube before it forced its way through the material.    An example would be a tent for summer use with a hydrostatic head measurement of 1000 mm. This means that the water in the tube got to 1000 mm high before it pushed its way through the fabric. ...

       The air permeability of a fabric is a measure of how well it allows the passage of air through it. The ease or otherwise of passage of air is of importance for a number of fabric end uses such as industrial filters, tents, sailcloth, parachutes, raincoat materials, shirting’s, down proof fabrics and airbags.                       Most woven fabrics such as those used for apparel, domestic and light industrial application are of relatively open construction. Measuring the air permeability of such fabrics can be carried out at low pressure differences and a number of instruments are available for the purpose.      In contrast, some materials such as leather, certain types of coated fabrics, and fabrics created for operating at increased pressure levels necessitate measuring their air permeability at appropriately high pressure levels that standard instruments are not able to provi...
