How Does Martindale Abrasion Tester Work?

          Qinsun instrument provides you with high quality Martindale Abrasion Pilling Tester which is calibrated and available at affordable price.It consists of four testing plates on which the abrading fabrics is attached, these four testing table are mounted on the base plate of the instrument. There is revolving plate, which revolves with the help of three cranks, pegs & motor.There are four sleeves attached on the revolving plate. The sample holders for abrasion & pilling testing are provided with the instrument. There is a set of weights for proper pressure on the test specimens. Templates for cutting the samples & abrading cloth and their mallet are also supplied as standard accessory.         Testing Principle Of Martindale Abrasion Tester :       Circle samples are grazed by fabrics with compatible material considering the recommended pressure in the trajectory of Lissajous movement, to accomplish certain turns and calculate the tested samples degree of p

ASTM F2100: Medical Face Masks Testing Machines List

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 strength test for face masks Material strength test for face mas

Meltblown Nonwoven Test: N95 Particle Filtration Efficiency (PFE) Tester

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

The List of Test Machines What A Masks Manufacturer Must Know

       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 pressures,and can also be used to determine the resistance to blood penetration
