I.Instrument use:
It is used to quickly, accurately and stably test the filtration efficiency and airflow resistance of various masks, respirators, flat materials, such as glass fiber, PTFE, PET, PP melt-blown composite materials.
II. Meeting Standard:
ASTM D2299—— Latex Ball Aerosol test
It is used to measure the gas exchange pressure difference of medical surgical masks and other products.
II.Meeting Standard:
EN14683:2019;
YY 0469-2011 ——-medical surgical masks 5.7 pressure difference;
YY/T 0969-2013—– disposable medical masks 5.6 ventilation resistance and other standards.
Instrument use:
The resistance of medical masks to synthetic blood penetration under different sample pressures can also be used to determine the blood penetration resistance of other coating materials.
Meet the standard:
YY 0469-2011;
GB/T 19083-2010;

I.Instrument Applications:
For non-textile fabrics, non-woven fabrics, medical non-woven fabrics in the dry state of the amount
of fiber scraps, raw materials and other textile materials can be dry drop test. The test sample is subjected to a combination of torsion and compression in the chamber. During this twisting process,
air is extracted from the test chamber, and the particles in the air are counted and classified by a
laser dust particle counter.
