Oxygen supplies for medicine and aircraft breathing
1 Scope
This standard specifies the requirements, inspection rules, test methods, packaging, marking, storage, transportation, and safety warnings of products of oxygen supplies for medicine and aircraft breathing.
This standard is applicable to gaseous and liquid oxygen supplies for medicine and aircraft breathing produced through air separation. It is mainly used for medical treatment, preparation of diving breathing mixture, aircraft breathing, etc.
Molecular formula: O2.
Relative molecular mass: 31.998 8 (as per the international relative atomic mass in 2005).
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments (excluding corrections) to, or revisions, of any of these publications do not apply. However, parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition applies.
GB/T 3863 Industrial oxygen
GB/T 5832.2 Determination of moisture in gases - Part 2: Dew point method
GB/T 8984 Determination of carbon monoxide, carbon dioxide and hydrocarbon in gases - Gas chromatographic method
JB/T 5905 Cryogenic liquid containers insulated with evacuated multilayer insulations
3 Requirements
3.1 The total pollutants in oxygen supplies for medicine and aircraft breathing shall not be toxic to the users.
3.2 The technical requirements for oxygen supplies for medicine shall meet those specified in Table 1.
3.3 The technical requirements for oxygen supplies for aircraft breathing shall meet those specified in Table 2.
Table 1 Technical requirements for oxygen supplies for medicine
Total hydrocarbon content (volume fraction)/10-6 ≤ 60
Solid substances Particle size/μm ≤ 100
Content/(mg/m3) ≤ 1
Note: For liquid oxygen supplies for aircraft breathing, no provisions are made for odor and moisture content.
4 Inspection rules
4.1 The manufacturer is responsible for the end-of-manufacturing inspection of oxygen supplies for medicine and aircraft breathing and the issuance of product quality certificates to ensure that all oxygen supplies for medicine and aircraft breathing delivered meet the requirements of the standard and are traceable.
4.2 For the bottled oxygen supplies for medicine and aircraft breathing, the manufacturers group them into batches by products produced by one operation shift or filled at one time, while the users group them based on the same vehicle loading volume or the same batch purchase volume. The products are randomly sampled 2% of the batch for inspection, with the sampling quantity of no less than 2 bottles and no more than 5 bottles. If any index in the inspection results fails to meet the requirements of the standard, double samples shall be taken from the same batch of products for re-inspection. If still failing to meet the requirements of the standard, the batch of products will be judged as rejected.
4.3 Liquid oxygen shall be taken from each storage and transportation container and inspected after vaporization. If any index in the inspection results fails to meet the requirements of the standard, the products will be judged as rejected.
4.4 The sampling safety of oxygen supplies for medicine and aircraft breathing shall be implemented according to the requirements of GB/T 3863.
