3 Terms and definitions
The following terms and definitions apply to this standard.
3.1
Separating human respiratory organs from the atmosphere, using oxygen generated by the oxygen of students, for people to escape in the event of a fire in the absence of oxygen
Respirator.
3.2
The respirator ensures the normal breathing performance of the human body during the protection time (such as inspiratory components, inhalation temperature, respiratory resistance, etc.).
3.3
The respirator can guarantee the normal breathing time of the human body; that is, when testing the protective performance of the respirator, the test performance index does not reach
The standard specifies the instantaneous time.
3.4
The instantaneous pressure difference between the suction port of the test device and the air bag when inhaling the protective performance of the respirator.
3.5
When testing the protective performance of the respirator, the instantaneous pressure difference between the exhalation port of the test device and the air bag is exhaled.
