For the brand new GB/T 32610-2016 which begins to implement in November 1st 2016 requires the technical specifications of oil and salt filtering efficiency, the particle protective performance for daily protective masks. It will standard the market and the product quality, but it will also bring a lot of changes for the overseas mask and respirator manufacturers.
Before GB/T 32610-2016 Technical specification of daily protective mask, there are GB 2626 General technical requirements for self-inhalation filter type dust respirator, GB 19038 Technical requirements for protective face mask for medical use and YY 0469 Technical requirements for surgical mask. But these standards are all for job safety or medical use. None of them is for ordinary people of daily life.
GB/T 32610 and GB 2626 require same particle filtration efficiency test as GB 19083. As the standard for medical use masks, GB 19083 standard requires splash resistance test to determine the blood penetration resistance performance (Measured by mask synthetic blood penetration tester) and bacterial filtration test to determine bacterial filtration performance(Measured by mask bacterial filtration efficiency tester). Because the splash resistance can evaluate the mask protective quality in the high risk environment when the user will face the potential risk from fluid and blood of patients, and the bacterial filtration efficiency can evaluate the bacterial protective performance.
There is serious fog and haze problem in China. For ordinary people, the useful protective mask will prevent the danger from haze and save their lives. Everybody in China cares so much about the physical health and the danger of haze, that’s why clean canned air sales so well in Chinese market. The new standard standardizes the scope, definition, grading, test methods, package and storage requirements for the daily protective masks. It will improve the market of daily respirator which don’t have standard before and provide ordinary people a reliable and useful specifications to choose and buy.
GB/T 32610 has four different levels: D, C, B and A. These levels are for different AQI(air quality index). Level A mask is for the condition that PM2.5 is below 500μg/m3, Level B mask is for the condition that PM2.5 is below 350μg/m3, Level C mask is for PM2.5 below 250μg/m3 and Level D mask is for PM2.5 below 150μg/m3 condition.
The standard also requires about filter efficiency and particle protective performance, respiratory resistance, formaldehyde, PH value, colorfastness, breaking strength and other properties. The standard gives full consideration to the protective performance and safety, even the use of comfort.
Personal daily protective mask is a big market in China, and it grows very fast along with the increasing of haze problems. Many mask manufacturers have already busy working for developing and testing the new masks which will accord with the requirements of standard. And many brands whose products are accorded with the requirements begin to cooperate with shopping website to prompt the products and are ready for the sales high tide annually in winter.
This year, everyone who cares about the haze and has doubts about choosing masks will be happy. Choosing a right and useful mask becomes easier than before. We just need to check it is according with the standard and passing the tests or not, and then we can buy dozens of four levels masks in order to wear in different day of different AQI(air quality index).
