Foreword
5.2, 5.3, 5.5, 5.6, 5.7, 5.10, 5.17, 5.19 of this standard are mandatory provisions, and the rest are recommended provisions.
This standard and the European Committee for Standardization CEN approved EN145-1997 "respiratory protector self-contained compressed oxygen or compressed oxygen
The degree of adoption of the Nitrogen Respirator Requirements, Tests, and Marks (English version) is non-equivalent. The main differences are as follows.
--- Modified some formatting formats according to Chinese habits;
--- Change some expressions applicable to international standards to those applicable to Chinese standards;
--- Added 180 to this category;
---The indicators of quantitative oxygen supply are different;
---The positive pressure performance test method is different;
---Reduced some component requirements.
This standard was proposed by the Fire Department of the Ministry of Public Security.
This standard is under the jurisdiction of the Fifth Technical Committee of the National Fire Protection Standardization Technical Committee.
This standard was drafted. Shanghai Fire Research Institute of the Ministry of Public Security.

3 Terms and definitions
The following terms and definitions apply to this standard.
3.1
The compressed oxygen is filled with a high-pressure oxygen cylinder as a gas source, and the oxygen in the oxygen cylinder is used when breathing, and the breathing chamber is not dependent on the external environment gas.
(or airbag) as a gas storage device, the air pressure in the mask is greater than the external atmospheric pressure of the respirator.
3.2
Includes respiratory protection from masks, breathing tubes, air bags, venting valves, and oxygen supply devices and connectors to the wearer's respiratory organs
system.
3.3
After the high pressure oxygen is depressurized, oxygen is continuously supplied to the respiratory system through the orifice at a prescribed flow rate.
3.4
Press the hand to apply the manual replenishment valve directly to the respiratory system.
