Foreword

This standard replaces GB/T 14599-1993 "high purity oxygen" and GB/T 14605-1993 "Determination of trace oxygen in argon, nitrogen and krypton Gas chromatography". This standard and GB/T 14599-1993 and GB/T 14605-1993 comparison, the main changes are as follows. --- Modify the scope to include pure oxygen, ultra-high purity oxygen and oxygen (GB/T 14599-1993 Chapter 1; Excerpts Chapter 1); --- The GB/T 14605-1993 after modifications incorporated into this standard 4.3; --- Revised technical requirements (GB/T 14599-1993 Chapter 3; Chapter 3 of this edition); --- Revised test method (GB/T 14599-1993, Chapter 4; Chapter 4 of this edition); The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee gases. This standard was drafted. Southwest Chemical Industry Research and Design Institute. The main drafters of this standard. He Daoshan, Chen Yali. This standard replaces the standards previously issued as follows. --- GB/T 14599-1993; --- GB/T 14605-1993. Oxygen, oxygen and ultra high purity oxygen

1 Scope

This standard specifies the pure oxygen, oxygen and ultra high purity oxygen of technical requirements, test methods, inspection rules, and packaging, labeling, transportation, storage Memory and so on. This standard applies to air separation and preparation of high purity gaseous oxygen and liquid water electrolysis preparation, mainly used for the preparation of standard gas mixture, Scientific research, production of integrated circuits and semiconductor devices as well as for other fields of high purity oxygen. Molecular formula. O2 Molecular Weight. 31.9998 (according to 2005 international relative atomic mass calculation)

3 Technical requirements

Oxygen, high purity oxygen, ultrapure oxygen shall meet the technical requirements of Table 1. Table 1 Technical Requirements project index Ultra-high purity oxygen oxygen oxygen Oxygen (O2) purity (volume fraction)/10-2 ≥ 99.995 99.999 99.9999 Hydrogen (H2) content (volume fraction)/10-6 ≤ 1 0.5 0.1 Argon (Ar) content (volume fraction)/10-6 ≤ 10 2 0.2 Nitrogen (N2) content (volume fraction)/10-6 ≤ 20 5 0.1 Carbon dioxide (CO2) content (volume fraction)/10-6 ≤ 1 0.5 0.1 Total hydrocarbon content (volume fraction) (methane meter)/10-6 ≤ 2 0.5 0.1 Water (H2O) content (volume fraction)/10-6 ≤ 3 2 0.5

4 test methods

4.1 Inspection Rules 4.1.1 oxygen, oxygen and ultra high purity oxygen by the manufacturer's quality inspection department inspection. Manufacturers should ensure that all products manufactured in line with Requirements of this standard. 4.1.2 bottled oxygen, high-purity oxygen according to the provisions of Table 2 random checks. When the test results do not meet any of the indicators specified in this standard , Then from the same batch of products to re-double sampling inspection. If there are any of the indicators do not meet this standard, then the product is not qualified.
