        How TüV Set up a Mask Test Lab in China at Record Speed

        How TüV Set up a Mask Test Lab in China at Record Speed

        Palas® Provides Advanced Mask Filtration Efficiency Measurement Technology to Help TüV SüD Develop Testing Capabilities During the Epidemic

        TüV SüD (China) is an independent technical inspection association. Over the last 150 years, TüV has added value to the partners and customers through a comprehensive portfolio of testing, certification, auditing, and advisory service.

        During the epidemic, the demand for efficient testing of masks has increased significantly. Therefore, TüV wanted to quickly establish a lab to provide fast and accurate tests that meet the highest standards. Palas® supported TüV with its advanced technology.

        Mastering Challenges during the Epidemic

        Since the beginning of 2020, the epidemic has rapidly spread to the world. Therefore, at the request of its headquarters, TüV China had the task to establish a mask efficiency testing department quickly. The biggest challenge TüV faced was the lack of professional equipment for the mask testing. “Most 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,” states the test supervisor of the TüV Mask Efficiency Laboratory.

        Palas® ensured Timely Help during the Epidemic

        When choosing measurement equipment, the focus of the TüV 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.

        Since Palas® offers high-quality solutions that meet all technical requirements for filtration efficiency testing, TüV 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® is very advanced in technology. We believe that there are not many suppliers of measurement equipment at the same level as Palas®," the laboratory test supervisor points out.

        After recognizing the rich experience and comprehensive filter testing technology of Palas® in the particle measurement industry, the relatively short delivery time became one of the important reasons for TüV to choose Palas® as their partner. Because Palas® is able to deliver on time during the global epidemic, TüV 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® technicians came to install and debug immediately. Around one week after the arrival of the PMFT 1000, we started to use Palas® PMFT 1000 for measurement."

        At present, the TüV mask filtration efficiency test laboratory conducts tests under EN 149 and GB 2626. The Palas® 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 TüV standard as much as possible.
