Mask Synthetic Blood Penetration Tester determine the resistance of medical protective masks to the penetration of synthetic blood under different test pressures. This Mask Testing Equipment can also be used to determine the blood penetration resistance of other coating materials. What is The Medical Mask Synthetic Blood Penetration Test Method ? 1. Add appropriate amount of synthetic blood from the filling hole. Generally need 500-1000ml. Connect the air tube of air compressor to the air filter.Then,connect the tube of the air filter to the machine. 2. Keep the air source pressure at 0.2MPa. Starting up, enter the test interface. 3. Click the "Shift" to change the test speed.This video uses 450cm/s as a demonstration. Click to"Inflate", wait until the inflation done.(The button will change from blue to white.). And then click "Spurt" to fill the whole pipe with synthetic blood. 4. Using a cup to collect the synthetic blood from the canula. Stop spurt and click "Inflate" again. Put a small cup at the entrance of the target plate to catch the excess synthetic blood. 5. After inflation done,click the "start" or the metal button on the panel to make thenozzle spray synthetic blood according to the set time. And observe whether the synthetic blood passes through the central hole of the target plate .If not, please use the handle toadjust the height of the nozzle to make it reach the appropriate height, and use the ruler to remember the height. 6. lnstall the sample. Open the back cover of the sample holder, stretch the prepared mask, place it on the raised disc,and close the back cover. After spurting, wait for 10 seconds for observation time. 7. Then take out the sample and observe the other side of the mask to see if the synthetic blood penetrates into it.lf there is penetration, it is unqualified. If not, it is qualified. GESTER Medical Face Mask Synthetic Blood Penetration Tester can fully simulate the human body's average blood pressure of 10.6kPa, 16kPa, and 21.3kPa spray speeds for testing.

What is The Fabric Flammability Test Method ? Vertical Flammability Chamber used for testing the flame retardant performance of afterflame, afterglow and carbonization of all farics in vertical direction. Comprises a draft free stainless steel cabinet with observation window and back wall painted black for easy test viewing. The different specimen holders and associated hardwares are dependent on the test standards. Textile Flammability Testing Principle Vertical Flame Test Chamber‎ Under controlled laboratory conditions, material response to heat and flame is measured and described. A test specimen is positioned vertically above a controlled flame and exposed for a specified period of time. Following exposure, the flame source is removed. Measurements are made on the length of time that the specimen continues to flame and the time afterglow continues after the flame source has been removed. Char length, or visible damage to the test specimen after application of a specified tearing force, is determined. Notations on observations of melting and dripping are also recorded. Flammability Testing Test Steps 1. Put the prepared sample into the fixture and hang it in the Vertical Flammability Testing Chamber. 2. Turn on the power of the device. 3. Select the language to enter the test interface. 4. Click the "Positive" button in the test interface tolet the burner run directly below the sample. 5. Use flame measuring scale to measure the distance betweenthe burner and the sample and adjust the position of the sample. 6. After adjustment, click“Rst", turn the burner back to initial position. 7. Set Flame Application time on test Interface, turn on the air source, click"AirSource", click"Ignition”(Initial ignite need to wait a while) 8. Turn the gas knob to adjust the flame size. 9. After the flame adjustment is complete, click Start.According to the burning state ofthe sample, click the "Afterflame time" button and “Aftergow time" button respectively. 10. After the combustion is completed, remove the sample. 11. Select the corresponding weight according to the sample,hang it on the sample to straighten the sample, and measurethe burning distance of the sample with a measuring ruler. GESTER has been concentrated on the research and development of physical testing instruments.

Abrasion resistance is defined as the ability of a material to withstand mechanical action such as rubbing, scraping, or erosion. It can improve the utilization efficiency of textiles and is an important indicator of the quality of textile products.One of astm taber abrasion detection methods: use Taber Abrasion Tester Taber abrasion resistance test machine to determine the wear resistance of materials and assess its wear resistance degree, like measuring its mass loss, thickness loss, and transmittance etc. Taber abrasion equipment Used to many materials, like suitcases, carpet, cardboard, clothing, glass, plastic coatins, metal coating, paint, varnishes, decorative sheets, high pressure sheets, plastics, textiles, flexible floor mats, traffic paint, tile, anodizing layer, blankets, electronic components, decorative plates, wax, label, leather, dental materials, automobile interior decoration, resin, furniture, etc. Taber Abrasion Machine Feature 1.Unique wear process. Place test sample on turntable and two abrasive wheel press on material to make material to wear. 2.Specimen turntable speed control options of both 60 rpm and 72 rpm. 3.Precision steel weights of 250 grams and 750 grams are furnished to provide standard wheel loads of 500 and 1000 grams.  Weights are marked to show total load on each wheel. This marking includes the weight of the abrading arm (250 grams). 4.Equip with vacuum cleaner to clear abrasive dusts. 5.Can test with different wear medium and accessories. When friction is the predominant factor causing deterioration of your materials, abrasion and wear testing provides data to compare materials or coatings and can help you predict the lifetime of your product.

About The Two Test Steps Of Abrasion Resistance And Pilling Resistance For Martindale The Martindale Abrasion and Pilling Tester is the standard method of determining the wear resistance of textiles or leather and the resistance to pilling. Samples are rubbed against known abradents at low pressures and in continuously changing directions and the amount of abrasion or pilling is compared against standard parameters.
