Foreword

This document complies with the provisions of GB/T 1:1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents" Drafting: This document is modified to adopt ISO 2046:1973 "Gaseous Oxygen for Aircraft Breathing": Compared with ISO 2046:1973, this document has made the following structural adjustments: ---Added normative reference documents in Chapter 2; ---Added Chapter 3 Terms and Definitions; ---Added Chapter 4 type; ---Chapter 5 corresponds to Chapter 2 in ISO 2046:1973, and Chapter 6 corresponds to Chapter 3 in ISO 2046:1973: The technical differences between this document and ISO 2046:1973 and their reasons are as follows: ---Added normative reference document GB/T 28285 (see Chapter 3) to adapt to my country's technical conditions; ---The gaseous oxygen type increases chemical oxygen production (see Chapter 4), which is currently widely used; --- Since the type of gaseous oxygen increases chemical oxygen production, the pressure, purity, moisture content and other requirements for chemical oxygen production are correspondingly increased (see Section 5 Chapter, 6:1 and 6:2): The following editorial changes have been made to this document: ---Change the name of the standard to "Gaseous Oxygen for Breathing by Civil Aircraft": Please note that some content in this document may be subject to patents: The publisher of this document assumes no responsibility for identifying patents: This document is proposed and coordinated by the National Aircraft Standardization Technical Committee (SAC/TC435): This document was drafted by: Hefei Jianghang Aircraft Equipment Co:, Ltd:, China Aviation Technology Research Institute, Shenyang Aircraft Industry (Collection) Group) Co:, Ltd:, Jinhong Gas Co:, Ltd:, and Guangdong Huate Gas Co:, Ltd: The main drafters of this document: He Wang, Fang Ling, Yang Bao, Ren Xiujun, Liu Wenbiao, Wang Bing, Wei Weidong, Wu Houtian, Ren Haitao, Xia Yan, Wang Cheng, Zhu Jun, Shi Dongsheng, Fu Zhuhong: Gaseous oxygen for breathing on civil aircraft

1 Scope

This document specifies the types, pressures and characteristics of gaseous oxygen for breathing by civil aircraft: This document applies to gaseous oxygen for breathing by personnel on board civil aircraft:

2 Normative reference documents

The contents of the following documents constitute essential provisions of this document through normative references in the text: Among them, the dated quotations For undated referenced documents, only the version corresponding to that date applies to this document; for undated referenced documents, the latest version (including all amendments) applies to this document: GB/T 28285 Aircraft Oxygen System Terminology

3 Terms and definitions

The terms and definitions defined in GB/T 28285 apply to this document:

4 types

Types of gaseous oxygen generally include high-pressure gas oxygen and chemically generated oxygen:

5 pressure

High-pressure oxygen should be filled into the oxygen cylinder at an effective pressure and reach its maximum working pressure: Note: The working pressure range of high-pressure oxygen for aircraft is 3MPa~21MPa: The maximum working pressure of chemical oxygen production should not exceed 343kPa:

6 features

6:1 Purity The purity requirements for gaseous oxygen used for breathing by civil aircraft are as follows: a) High-pressure oxygen, the oxygen content percentage should not be less than 99:5%, and the maximum concentration of other main components should meet the requirements specified in Table 1: Table 1 Maximum concentrations of other main components of high-pressure oxygen Category Hyperbaric Oxygen Carbon dioxide 0:01% Carbon monoxide 0:0005%
