YY0969-2013 Disposable Medical Mask is suitable for covering the user's mouth, nose, and jaw, and is used for wearing and blocking the exhalation or spraying of pollutants from the mouth and nasal cavity in ordinary medical environments. This standard does not apply to medical protective masks or surgical masks At present, the testing of medical masks involves three existing national standards: YY 0969-2013 "Disposable Medical Masks", YY 0469-2011 "Medical Surgical Masks", and GB 19083-2010 "Technical Requirements for Medical Protective Masks". Among them, disposable medical masks are widely used. Due to the complexity of the production of medical masks, if they are all produced according to the requirements of protective masks, the production volume cannot reach the usage volume. Therefore, disposable medical masks occupy a large market Disposable medical masks are tested according to the YY 0969-2013 standard. Although they are disposable items, their protective effect is not inferior to protective masks. The YY0969-2013 standard also has strict requirements for bacterial filtration efficiency YY0969-2013 Disposable Medical Mask Test Items:

01. Appearance:

The mask should have a clean and intact appearance, with no damage or stains on the surface

02. Structure and size:

After wearing the mask, it should be able to cover the wearer's mouth, nose, and forehead.

. It should comply with the designed dimensions, and the large deviation should not exceed ± 5%

03. Nose clip:

The mask should be equipped with a nose clip, which is made of plastic material.

The length of the nasal clip should not be less than 8.0cm

04. Nose and mouth straps:

The breaking strength at the connection point between each mask strap and the mask body should not be less than 10N

05. Bacterial filtration efficiency:

The bacterial filtration efficiency of masks should not be less than 95%

06. Ventilation resistance:

The ventilation resistance between the two sides of the mask for gas exchange should not exceed 49Pa/cm2

07. Microbiology:

A. Non sterile masks should meet the requirements in the table below B. Sterilized masks should be sterile

08. Residual amount of ethylene oxide:

If the mask is sterilized or disinfected with ethylene oxide, the residual amount of ethylene oxide should not exceed 10 μ G/g

09. Cytotoxicity:

The cytotoxicity of masks should not exceed level 2 10. Skin irritation: The primary irritation score for masks should not exceed 0.40 11. Delayed hypersensitivity reaction: The delayed hypersensitivity reaction of masks should not exceed level 1 The above article is a partial list.
