    The small weave of the net introduces the standard of mask for everyday protection.

    With the advent of autumn and winter, the troubles caused by haze seem to become Tucao spots again.

    However, in the face of a wide variety of mask products, which can really play a role in preventing inhalable dust? What are the criteria for prevention? Not only ordinary consumers, but also manufacturing enterprises.

    A few days ago, the standard formulation of "daily protective mask technical specification" will be held in Beijing, and the production standards of daily protective masks against fog and haze will be introduced.

    It is reported that there are three domestic mask standards: GB 2626-2006 "respiratory protective equipment - self suction filter particulate respirator", GB 19083-2010 "medical respirator technical requirements", YY 0469-2011 "medical surgical mask".

    According to the standard classification, the first one belongs to labor.

    Protective products

    Standards and the latter two belong to the standard of medical protective products. Because of the different environment and different objects of protection, none of them can be completely applied to the PM2.5.

    Because there is no standard specification, the detection of the civil respirator is the choice of a certain standard by the production and testing organizations, resulting in the confusion of different test results of similar products.

    The participants in this standard include mask production enterprises, core filtration material manufacturers, testing institutes and research institutes. In the preparation, the names, technical items and testing methods of making use of masks in daily life have been fully discussed, and a consensus has been reached: the declaration of standards is open and pparent.

    In accordance with the declaration procedures for national standards, proposals for formulating standards for respirators used in people's daily lives and

    standard

    The draft is publicized and widely solicited.
