What equipment is used for mask testing

Original title: Recommendation for a complete set of mask testing equipment


     With the outbreak and continuation of the epidemic, in this fight against the new coronavirus epidemic, we learned from major media that wearing a mask is the most effective way to prevent the spread of the virus. For a time, medical masks became a scarce resource. Because of scarcity, many people have no choice but to use “cotton masks” and “homemade plastic masks” instead of medical 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, only to meet 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 domestic mask production are listed as follows:


      GB 19083 Medical protective mask


      GB/T 32610 Daily protective mask


      YY 0469 Medical surgical mask


      YY/T 0969 disposable medical mask


      Therefore, in response to the above standard requirements, Jinan Zhongce Electromechanical Equipment Co., Ltd. provides the following medical mask testing equipment:


      1. Test items of mask particle filtration efficiency



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
NoYY/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 levels according to the standard. One level is the filtration efficiency greater than 95%.


Recommended testing equipment: Zhongce PFT-01 mask particle filtration efficiency tester, this tester is suitable for medical protective masks, medical surgical masks, ordinary medical masks and other particle pass efficiency tests.

2. Breaking strength and static tensile test items


Breaking strength of the connection point between the mask belt and the mask bodyNot less than 10NGB 19083 Medical protective mask
The breaking strength of the mask belt and the connection between the mask belt and the coverGreater than or equal to 20NGB/T 32610 Daily protective mask
Fastness of exhalation valve cover (10N, 10S)There should be no slippage, fracture, or deformationGB/T 32610 Daily protective mask
Mask band breaking strengthNot less than 10NYY 0469 Medical surgical mask
Mask with static tensionNot less than 10NYY/T 0969 disposable medical mask

Recommended equipment: Zhongce TST-02H mask belt tensile testing machine (professional name is intelligent electronic tensile testing machine) + special test fixture


3. Detection items of mask ventilation resistance and pressure difference


Airflow resistanceThe gas flow rate is 85L/min, and the suction resistance shall not exceed 343.2pa (35mmH2O)GB 19083 Medical protective mask
Inspiratory resistanceLess than or equal to 175pa

GB/T 32610 Daily Protection Type

Exhalation resistanceLess than or equal to 145paGB/T 32610 Daily protective mask
Pressure differenceNot more than 49paYY 0469 Medical surgical mask
Ventilation resistanceNot more than 49pa/cm2YY/T 0969 disposable medical mask


Related equipment: Zhongce TQD-02 mask ventilation resistance and pressure difference detector is used to measure the ventilation resistance and pressure difference of masks under specified conditions.

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
NoYY/T 0969 disposable medical mask
NoGB/T 32610 Daily protective mask

Recommended equipment: Public test 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

Five, mask flame retardant performance test items

   

The materials used should not be flammable, and the burning should not exceed 5s after being removed from the flame

GB 19083 Medical protective mask
The materials used should be non-flammable materials, and the mask burns no more than 5s after leaving the flameYY 0469 Medical surgical mask
NoYY/T 0969 disposable medical mask
NoGB/T 32610 Daily protective mask

Recommended equipment: Zhongce FRT-01 mask flame retardant performance tester is suitable for the determination of the flame retardant performance of medical masks and all protective masks.
