What are the characteristics of the filter efficiency tester for mask particles developed by Guangzhou Standard International?

There are two main standards for the particle filtration efficiency tester of masks developed by Guangzhou Interstandard Packaging Equipment Co., Ltd., one is the national standard, and the other is the American standard, which is mainly used to test the particle filtration efficiency of daily protective masks and medical masks, and to determine the barrier performance of ordinary fabrics and medical protective masks to constant airflow. It is suitable for medical device inspection centers, safety protection inspection centers, labor protection inspection centers, drug inspection centers, disease prevention and control centers, textile inspection centers, hospitals, mask manufacturers, etc.

Meet the standard: GB/T? 326 10-20 16? 、GB？ 2626-2006? 、GB？ 19082-2009? 、GB？ 19083-20 10? 、GB？ 24539-2009? 、YY？ 0469-20 1 1? 、YYT0969-20 13
