    With the development, the quality of air is getting worse and worse, so more and more people wear masks to protect smoke and dust.

    Recently, China's first "daily protective mask technology specification".

    Country

    The standards were promulgated.

    It is understood that the protection effect and safety performance of fine particulate matter (PM2.5) are the two key indicators of the "daily protective mask technical specification".

    This standard is applicable to respirators that are used to remove particulates in air pollution environment in everyday life.

    The standard will be formally implemented in November 1, 2016.

    However, this standard does not apply to children's respirators.

    The protection effect is the core index of the standard.

    Protective effect

    The fruit grade is set according to the air quality category of the national air quality standard, and the protection effect grades are divided into four levels from low to high: D, C, B and A-level, the corresponding environment is as follows: D level is suitable for moderate (PM2.5 concentration less than 15 mg / m3) and the following pollution, C level is suitable for severe (PM2.5 concentration less than 250 microgram / cubic meter) and the following pollution, B level is suitable for serious pollution (PM2.5 concentration is less than 350 micrograms / cubic meter), class A is used at PM2.5 concentration of 500 micrograms / cubic meter.

    Wearing masks according to standard requirements can reduce the concentration of inhaled PM2.5 to less than 75 micrograms / cubic meter, so that the air quality in inhalation can reach the level of above and above.

    Safety performance is an important indicator of the standard.

    In order to ensure the safety of consumers when wearing protective masks, the standard requires that masks should be securely and firmly protected at the mouth and nose. There should be no sharp sharp corners and sharp edges. The criteria for formaldehyde, dyes, microorganisms and other harmful elements that may cause harm to human body are specified in detail.

    Taking into account the safety of the wearer when walking, the standard stipulates that the visual field below the mask should not be less than 60 degrees, so that the wearing of the wearer can be avoided because of the high arch design of the mask.

    In addition, due to the large differences in physical characteristics of children,

    Respiratory resistance

    The accumulation of medical data and experimental data for children's growth needs to be perfected. Therefore, this standard does not apply to children's respirators.
