Inventory of mask testing items: medical masks, medical surgical masks, KN95 masks

Can printed and dyed masks be used with confidence? Are children's masks reliable? How protective are medical masks? These problems can be solved by mask testing. The masks purchased by consumers through formal channels have been tested by authoritative institutions, so they can be purchased with confidence. Masks are divided into medical masks, non-medical masks, civilian sanitary masks, etc. Zhongke Testing has CMA&CNAS qualifications for various mask testing, and the laboratory has full testing capabilities for mask testing, and can compile mask testing reports.

Mask detection range

Zhongke testing masks include: non-woven masks, polymer masks, activated carbon masks, disposable masks, medical protective masks, medical surgical masks, general medical masks, industrial dust masks, and civilian protective masks.

Mask & Protective Clothing Tester detection process:

1. Project application - submit a mask standard test application to the testing engineer of Zhongke.

2. Data preparation - According to the mask testing requirements, the company prepares relevant test documents.

3. Mask testing - The company sends the samples to be tested to the mask testing laboratory for testing.

4. Prepare report - the engineer prepares the report according to the test data.

5. Report review - the engineer will review the complete report and issue a report.

6. Mailing - report mailing companies.
