    Anti Haze MaskStandardTechnical Specification

      

    north

    The area has entered the haze prone period, and the important way for the public to cope with haze is wearing masks.

    Reporter survey found that the current market masks vary widely, good and bad, against haze and no national standard mask technology specifications.

    Reporters found that there are basically two kinds of masks in the market. One is medical masks. Its main role is to prevent saliva infection between doctors and patients. It has little effect on haze prevention. The other is industrial production protective products, which can intercept particles in the air.

    Director of the Institute of low carbon development of the Liaoning Academy of Social Sciences, bidi Li, said that the national standards of respiratory protective equipment, self suction particulate filter respirator (GB2626-2006) issued in 2006 were basically made for labour protection products and are not completely suitable for public anti haze.

    "For example, this

    standard

    The detection temperature of product components is set at 25 C (+ 5), which is quite different from the winter temperature in northern regions where fog and haze occur frequently.

    Bi Dali said that this standard is not compatible with anti haze requirements in terms of testing and application.

    The material standard of making haze mask can eliminate the fake and inferior products in the market, and prevent the criminals from drilling policy.

    At the same time, we should also formulate technical requirements and monitoring methods for production of anti haze masks and masks, and standardize the production of quality products by enterprises.

    The reporter consulted the quality supervision department of Liaoning province.

    Other party

    At present, there is no national standard for anti haze masks.

    In this regard, biudley believes that the safety standards of haze respirators and masks should be formulated from the national level, and the production approval and market access system should be adopted.
