Breathing resistance detection method

Breathing resistance detection method

At present, the standards based on which international testing agencies test the respiratory resistance of respiratory protective equipment are JIS T8151-2005 (dust mask), BsEN 136-1998 (respiratory protective device. Full face mask. Requirements, tests, markings), GB 2626-2006 (Respiratory protective equipment, self-priming filter type anti-particulate respirator”, GB 2890-2009 (Respiratory protection, self-priming filter type gas mask), etc., the detection principle of respiratory resistance in the above standards is basically the same, and the composition of the detection device system is basically the same and different It lies in the choice of test gas flow.
