【Scope of application】

It is used to determine the inhalation resistance and exhalation resistance of respirators and masks under specified conditions. Applicable to national labor protection equipment inspection agencies and mask manufacturers to carry out related tests and inspections of ordinary masks, dust masks, medical masks, and anti-smog masks. It can be used by manufacturers, scientific research units and third-party testing institutions to conduct KP and KN anti-particle respirators and related products are tested.
