\nDuring the epidemic, the demand for efficient testing of masks has increased significantly. Therefore, T\u00dcV wanted to quickly establish a lab to provide fast and accurate tests that meet the highest standards. Palas\u00ae supported T\u00dcV with its advanced technology.<\/p>\n
Mastering Challenges during the Epidemic<\/strong><\/p>\n Since the beginning of 2020, the epidemic has rapidly spread to the world. Therefore, at the request of its headquarters, T\u00dcV China had the task to establish a mask efficiency testing department quickly. The biggest challenge T\u00dcV faced was the lack of professional equipment for the mask testing. \u201cMost of the mask filter efficiency test equipment manufacturers cannot guarantee the delivery time in the early stage of the epidemic, and there is no room for negotiation on the price. Also, most of the testing rig could not give us sufficient confidence in the accuracy of the aerosol concentration detection,\u201d states the test supervisor of the T\u00dcV Mask Efficiency Laboratory.<\/p>\n Palas<\/strong>\u00ae<\/strong> ensured Timely Help during the Epidemic<\/strong><\/p>\n When choosing measurement equipment, the focus of the T\u00dcV Mask Efficiency Laboratory is the main technical parameters in the mask testing standards, such as particle concentration and particle number. “Most suppliers can only build equipment by using common sensing elements on the market, but they are lacking in key technologies,” explains the laboratory test supervisor.<\/p>\n Mask Filtration Efficiency Tester PMFT 1000 at a Glance<\/strong><\/p>\n Advantages\uff1a<\/strong><\/p>\n \u2022\u00a0 \u00a0Test rig working principle meets EN 149\/NIOSH\/GB 2626\/ASTM F2299-3\/ASTM F3502-2021\/CWA 17553 Applications\uff1a![\"\"](\"https:\/\/palas.com.cn\/en\/wp-content\/uploads\/2021\/03\/2-1.jpg\")
\nSince Palas\u00ae offers high-quality solutions that meet all technical requirements for filtration efficiency testing, T\u00dcV was convinced that they have chosen the right partner, and with the PMFT 1000 they found exactly the test rig they needed. “No matter from the aerosol generator to the flow control, Palas\u00ae is very advanced in technology. We believe that there are not many suppliers of measurement equipment at the same level as Palas\u00ae,” the laboratory test supervisor points out.<\/p>\n![\"\"](\"https:\/\/palas.com.cn\/en\/wp-content\/uploads\/2021\/03\/3-1.jpg\")
\nAfter recognizing the rich experience and comprehensive filter testing technology of Palas\u00ae in the particle measurement industry, the relatively short delivery time became one of the important reasons for T\u00dcV to choose Palas\u00ae as their partner. Because Palas\u00ae is able to deliver on time during the global epidemic, T\u00dcV was able to develop its own mask testing capabilities timely during the special period. “In just 2 months after the decision, we received the test rig, and the Palas\u00ae technicians came to install and debug immediately. Around one week after the arrival of the PMFT 1000, we started to use Palas\u00ae PMFT 1000 for measurement.”<\/p>\n![\"\"](\"https:\/\/palas.com.cn\/en\/wp-content\/uploads\/2021\/03\/4.jpg\")
\nAt present, the T\u00dcV mask filtration efficiency test laboratory conducts tests under EN 149 and GB 2626. The Palas\u00ae technical support team changed and upgraded the software operating process accordingly, and actively participated in the verification of the technical parameters, so that the measurement process could meet the requirements of the T\u00dcV standard as much as possible.<\/p>\n
