Oxygen supplies for medicine and aircraft breathing
1 Scope
This Standard specifies requirements, inspection rules, test methods as well as
packaging, marks, storage, transportation and safety warning for oxygen
supplies for medical and aircraft breathing.
This Standard is applicable to gaseous and liquid medical oxygen prepared
from separated air, aviation breathing oxygen, mainly used for medical
treatment, preparation of diving breathing mixed gas, aviation flight breathing.
Molecular formula: O2.
Relative molecular mass: 31.988 (calculated according to international relative
atomic mass in 2005).

3 Requirements
3.1 The total pollutants of medical oxygen and aircraft breathing oxygen shall
not be toxic to users.
products produced by an operation team in a production plant or filled at one
time. The user batches according to the same vehicle volume or the same batch
of purchase volume. Randomly sample according to 2% of the batch for
inspection. Sampling quantity shall not be less than 2 bottles, nor more than 5
bottles. When any indicator in the inspection result does not meet the
requirements of this Standard, it shall resample the double quantity from the
same batch of products to inspect. If any of the indicators still does not meet
the requirements of this Standard, the batch of products shall fail.
4.3 For liquid oxygen, it shall take liquid sample from each storage container to
inspect after vaporization. When any of the indicators in the inspection result
does not meet the requirements of this Standard, this product shall fail.
4.4 The safety of medical oxygen and oxygen sampling for aircraft breathing
shall be in accordance with the provisions of GB/T 3863.
5 Test methods
5.1 Determination of oxygen content
In accordance with GB/T 3863.
5.2 Determination of moisture
In accordance with GB/T 5832.2.
5.3 Determination of carbon monoxide and carbon dioxide
In accordance with GB/T 8984.
5.4 Determination of gaseous acidic and alkaline substances
5.4.1 Reagents and solutions
The requirements for reagents and solutions are as follows:
-- Distilled or deionized water;
-- Hydrochloric acid solution: 0.01mol/L;
-- Ethanol solution: 60 × 10-2 (mass fraction);
-- Ethanol solution: 20 × 10-2 (mass fraction);
-- Methyl red indicator: 0.2 × 10-2 (mass fraction) ethanol solution. It is
prepared by dissolving 0.2g of methyl red in 100mL of ethanol [60 × 10-2
(mass fraction)] solution;
-- Acetic acid: analytically pure;
-- Potassium iodide: analytically pure;
-- Soluble starch: analytically pure;
-- Mixture of starch and potassium iodide: Dissolve 0.5g of potassium iodide
in 95mL of heating water. Then mix 0.5g of starch with 5mL of cold water.
Slowly pour the mixture into the boiling potassium iodide solution while
stirring. Boil 2min~3min.
5.5.2 Instruments
The requirements for Instruments are as follows:
-- Indexing pipette: capacity of 1mL;
-- Montessori gas washing bottle: capacity of 100mL;
-- Gas flow meter;
-- Measuring cylinder: capacity of 100mL.
5.5.3 Determination
Use sampling tube to connect the decompressed medical oxygen to the gas
washing bottle and gas flow meter. Turn on the sample gas and blowing-
washing bottle for 1min~2min
Inject 100mL of freshly-prepared starch and potassium iodide mixed solution
into the gas washing bottle. Add 1 drop of acetic acid.
Within 30min~35min, make 2000mL of oxygen pass through the gas washing
Observe the solution in the washing bottle. If it still remains colorless, the ozone
and other gaseous oxidants are shall be determined as conforming.
5.6 Determination of odor
Determine the odor through olfactory organs. Slightly open the bottle valve. The
outflowing oxygen shall be free of odor.
5.7 Determination of total hydrocarbon content
In accordance with GB 8984.
5.8 Determination of solid substances
containing the sample gas, the dust trap and the flow meter in sequence.
5.8.4 Analysis
Turn on the sample gas steel cylinder. Adjust the flow rate within the rated value
of the flow meter.
Access to the sample gas for more than 1m3. Take out the filter paper to weigh.
The difference between the relative humidity of the balance chamber shall not
exceed 100% when weighing twice before and after.
5.8.5 Result processing
The content of solid substances in oxygen is calculated according to formula
X1 - Content of solid substances, in milligrams per cubic meter (mg/m3);
m1 - Mass of filter paper before sampling, in milligrams (mg);
m2 - Mass of filter paper after sampling, in milligrams (mg);
V - Sampling volume converted at 20°C and 101.3kPa, in cubic meters (m3).
5.9 Determination of solid particle size
Place the filter paper that is weighed in 5.8 under a microscope of approximately
40 times to observe. There shall be no particles larger than 100μm.
6 Packaging, marks, storage, transportation and safety
6.1 The general provisions shall be implemented in accordance with GB/T 3863
and JB/T 5905.
6.2 Piston seals on compressors for compression filling or pressurized delivery
shall not use fluoroplastics or other materials that have not been qualified by
the medical inspection department.
