Recommended testing equipment for medical masks

With the outbreak and continuation of the epidemic, in this fight against the new coronavirus epidemic, we have learned from major media that wearing a mask is the most effective means of preventing the spread of the virus. For a time, medical masks became a scarce resource. Because of scarcity, many people have no choice but to replace medical masks with “cotton masks” and “homemade plastic masks”, thinking that as long as they cover their mouth and nose, they can prevent viruses. As everyone knows, the design and production of medical masks are based on standards, and only reach the standard can be regarded as a mask that can effectively block the spread of the virus.


So, what standards do medical masks refer to? What are the corresponding mask testing equipment?


This time, the main reference test standards for mask production are listed as follows:


  1. GB 19083 Medical protective mask
  2. GB/T 32610 Daily protective mask
  3. YY 0469 Medical surgical mask
  4. YY/T 0969 disposable medical mask


Therefore, in response to the above standard requirements, horizontester provides the following medical mask testing equipment:


1.Test items of mask particle filtration efficiency


Property Data
The filtration efficiency of the mask filter material should not be less than 30% GB 19083 Medical protective mask
The filtration efficiency of the mask for non-oily particles should not be less than 30% YY 0469 Medical surgical mask
No YY/T 0969 disposable medical mask
The filtration efficiency of salty particles and oily particles is divided into three levels: Ⅰ ≥99%, Ⅱ 95%, Ⅲ 90% GB/T 32610 Daily protective mask


The filtration efficiency is divided into three grades according to the standard. One level is the filtration efficiency greater than 95%.

Recommended testing equipment: Horizontester PFT-01 mask particle filtration efficiency tester is suitable for the test of particle filtration efficiency of medical protective masks, medical surgical masks, and ordinary medical masks.

2.Breaking strength and static tensile test items


The breaking strength of the connection point between the mask belt and the mask body Not less than 10N GB 19083 Medical protective mask
The breaking strength of the mask belt and the connection between the mask belt and the mask body Greater than or equal to 20N GB/T 32610 Daily protective mask
Fastness of exhalation valve cover (10N, 10S) There should be no slippage, fracture, or deformation GB/T 32610 Daily protective mask
Mask band breaking strength Not less than 10N YY 0469 Medical surgical mask
Mask with static tension Not less than 10N YY/T 0969 disposable medical mask


Recommended testing equipment: Horizontester TST-02H mask belt tensile tester (professional name is intelligent electronic tensile tester) + dedicated test grips

3.Test items of mask ventilation resistance and pressure difference


Airflow resistance The gas flow rate is 85L/min, and the suction resistance shall not exceed 343.2pa (35mmH2O) GB 19083 Medical protective mask
Inspiratory resistance Less than or equal to 175pa GB/T 32610 Daily protective mask
Exhalation resistance Less than or equal to 145pa GB/T 32610 Daily protective mask
Pressure difference Less than or equal to 145pa YY 0469 Medical surgical mask
Ventilation resistance Not more than 49pa/cm2 YY/T 0969 disposable medical mask


Recommended testing equipment: horizontester TQD-02 mask ventilation

resistance and differential pressure tester is used to measure the ventilation resistance and pressure difference of masks under specified conditions.

Mask Ventilation Resistance And Differential Pressure Tester

Horizontester TQD-03 mask airflow resistance and breathing resistance tester is used to determine the inhalation and exhalation resistance of masks under specified conditions, and it can also be used to determine the air penetration resistance of textiles, cotton wool, space cotton, masks, etc.

4.Mask synthetic blood penetration test items


The synthetic blood is sprayed onto the mask sample at a pressure of 160mmHg, and there should be no penetration inside the mask GB 19083 Medical protective mask
After 2ml of synthetic blood is sprayed on the outside of the mask at a pressure of 16.0kpa (120mmHg), there should be no penetration on the inside of the mask YY 0469 Medical surgical mask
No YY/T 0969 disposable medical mask
No GB/T 32610 Daily protective mask


Recommended equipment: Horizontester BPT-01 mask synthetic blood penetration tester is used to test the filtration efficiency of daily protective masks, medical masks and respirators on particulate matter

5. Test items for the protective performance of mask particles


GB/T 32610 Daily protective mask


Requirements for the protective effect of masks with different protective effect levels


Protection effect level Class A Class B Class C Class D
Protection effect/%      ≥ 90 85 75 65


When the protective effect level of the mask is A, the filtration efficiency should reach II and above; when the protective effect of the mask is B, C, and D, the filtration efficiency should reach III and above 


Recommended equipment: Mask PM protective effect tester PFY-01 is used to test the protection effect of daily protective masks, medical masks and respirators on particles.
