The current epidemic of new coronavirus pneumonia is still spreading. China's mask production capacity has been stepped up to recover, but in the face of a huge gap, it is still in short supply. China has also begun to encourage qualified enterprises to switch to production masks, and many domestic companies have responded to the call to switch to production masks.
How do you know if a mask is protective? I believe that every newly converted mask manufacturer wants to know. The following will give you the answer:
In each country, there are relevant mask standards to control the masks quality, thereby effectively helping the masks to be sold domestically or externally. Specific test items are specified within specific standards, and each test item specifies specific test methods and parameter requirements. Once the standards are determined, you know which items need to be tested? What instruments are used for testing?
Just like a disposable medical face masks manufacturer in china ,there are three test instruments for testing and quality control.such as BFE Tester、airflow tester 、Dry microbial penetration resistance tester .
