 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 However, the standard of EN14683:2004 has been replaced by EN14683:2019 version, for air flow leakage issue, the standard propose higher requests for assuring testing result accuracy.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 ...

     The mask material was tested with synthetic blood under continuous applied pressure, and the penetration of synthetic blood on the material was visually checked.Mask Synthetic Blood Penetration Tester is suitable for the resistance of masks to the penetration of synthetic blood under different levels of the test pressure.          Medical masks synthetic blood penetration tester is used to determine the resistance of medical protective masks to penetration by synthetic blood at different test pressures,and can also be used to determine the resistance to blood penetration of other coating materials.    The convex sample fixing device can simulate the actual state of use of a mask, leave a test target area without damaging the sample, and distribute the synthetic blood in the target area of the sample.    It can fully simulate the human body's average blood pressure of 10.6kPa, 16kPa, and 21.3kPa spray speeds fo...

    Surgical mask has good filtration effect on bacteria and viruses, breathable, comfortable and clean, and is widely used by modern doctors.The surgical mask is subdivided into three types according to its usage: disposable surgical mask, surgical mask and medical protective mask.Disposable surgical mask is suitable for wearing and blocking the exhalation or ejection of pollutants in the oral cavity and nasal cavity in the general medical environment.        The following are the basical test machines which are used to test the quality of  melt-blown nonwovens for making  Surgical mask. Qinsun intruments company is a textile test machines manufacturer .we also have the test machines for masks testing .          The melt-blown nonwovens are made of thermoplastic synthetic polymer, directly from the polymer stage to randomly-laid nonwoven mat or fabrics by using the melt-blown spinning process.The non-woven fabric...

   Face Mask Particulate Filtration Efficiency Tester (PFE) is to test the filtering efficiency of particulate protective masks and medical masks and to determine the resistance of ordinary fabrics and medical protective masks to the constant flow of airflow.        Face Mask Particulate Filtration Efficiency(pfe) Tester is designed to test the filtering efficiency of particulate protective masks and medical masks and to determine the resistance of ordinary fabrics and medical protective masks to the constant flow of airflow.         PFE tester is used to detect the filtration efficiency of particulate matter such as daily masks and filters.It is applicable to medical equipment inspection center, safety protection inspection center, labor protection inspection center, drug inspection center, disease prevention and control center, hospital, mask and respirator manufacturer, etc.   The Particulate Filtration Efficiency （PFE）...

Masks test machines manufacturer :      ASTM F2100-19 is intended for use by those constructing medical face masks. This standard does not apply to regulated respiratory protection, nor does it cover medical  face masks for all possible use situations. For example, as stated in the ASTM F2100-19 document, “the Centers for Disease Control and Prevention (CDC) specifically  requires NIOSH respirators that are at least 95% efficient for tuberculosis exposure control.”       This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. Examples of test items and machines for ASTM F2100 :      ASTM F2100: Medical face masks testing Relevant test machines Material ...

Face Mask Particulate Filtration Efficiency Tester is designed o test the filtering efficiency of particulate protective masks and medical masks and to determine the resistance of ordinary fabrics and medical protective masks to the constant flow of airflow. The PFE tester with particle generator can provide sodium chloride particles and paraffin oil particles. It can measure the particle penetration, filtering efficiency and the breathing resistance delta P. It is widely used in quality control, research and development, certification, manufacturing or testing industry, etc. It is used to detect the filtration efficiency of particulate matter such as daily masks and filters.It is applicable to medical equipment inspection center, safety protection inspection center, labor protection inspection center, drug inspection center, disease prevention and control center, hospital, mask and respirator manufacturer, etc. Features of Face masks particle filtration efficiency (PFE) teste...
