▌   Mask Type
With the spread of the novel coronavirus pneumonia, medical protective products such as masks have become daily necessities, building a key line of defense for health and safety. Masks are divided into disposable medical masks, medical protective masks, PM2.5 protective masks, daily protective masks, etc.

▌What projects are included in mask testing?

1. Appearance inspection: mainly inspect the size, shape, wrinkles, odor, etc. of the mask, and the mask must not be damaged, cracked, or have any welts.

2. Material testing: including the raw materials, ingredients, safety and other aspects of the mask.

3. Filtration efficiency test: Test the filtration efficiency of the mask. Generally speaking, the higher the filtration efficiency of the mask, the more it can prevent the spread of viruses and bacteria.

4. Breathability test: Test the breathability of the mask to avoid "carbon dioxide poisoning" after wearing the mask.

5. Durability testing: Test the durability of the mask to prevent it from losing its protective effect after being worn for a long time.

6. Microbiological testing: Check whether there is biological contamination such as bacteria and fungi on the mask.

▌What are the mask testing standards?

1. Appearance standard: The size of the mask meets the requirements, there are no cuts, cracks, broken threads, no odor, etc.

2. Material standards: The inspection report of mask raw materials should comply with the written and electronic standards.

3. Filtration efficiency standard: The filtration efficiency of the mask should meet the relevant national standards, such as the European EN149 standard, the Chinese GB2626 standard, etc.

4. Breathability standards: The osmotic pressure and breathability of the mask should meet national standards.

5. Durability standard: The mask should be able to be recycled multiple times without losing its fundamental protective power.

6. Microbiological standards: After testing, the mask should be free of microbial contamination such as bacteria and fungi.
