GB/T3863-1995 Technical Specification for Oxygen in Industrial Use
Oxygen is one of the most important components of air, accounting for about 20.9% of the atmosphere, and it is also essential to human life. In the industry, oxygen is applied to manufacture, cleaning, welding and cutting of steel, as well as chemical process industry. GB/T3863-1995 Technical Specification for Oxygen in Industrial Use is designed to regulate the requirements, test methods and inspection of oxygen to meet the requirements of industrial use.
The oxygen used in industrial use should comply with the safety and health requirements. The oxygen must be pure, not containing a variety of impurities. It may be obtained from natural air and contains no anti-oxygen additive. GB/T3863-1995 defines the specification of oxygen purity, packaging, labeling and other content in detail. The purity of oxygen is divided into five grades, including grade OX-1, grade OX-2, grade OX-3, grade OX-4 and grade OX-5. In accordance with their respective regulations, each grade of oxygen purity must be not lower than certain requirements. Grade OX-1 oxygen purity must not be less than 99.7%, Grade OX-2 oxygen purity must not be less than 99.5%, Grade OX-3 oxygen purity must not be less than 99.2%, Grade OX-4 oxygen purity must not be less than 98.2%, Grade OX-5 oxygen purity must not be less than 97.0%.
Moreover, the oxygen used for industrial use must be carefully packed in special packaging materials that keep the oxygen purity unchanged during transportation and storage. In addition, oxygen packages should be clearly labeled with their oxygen grade according to GB/T3863-1995. The oxygen should also be sealed in properly closed bags, boxes or other containers to prevent any leakage of oxygen during transportation and storage.
GB/T3863-1995 also sets forth the detailed requirements for testing and inspecting the oxygen used for industrial use. Before use, oxygen should be tested and inspected to ensure that the oxygen is under the requirements of oxygen safety regulations and other related standards issued by government. Oxygen should also be tested regularly to ensure that the oxygen gases are within the requirements.
GB/T3863-1995 Technical Specification for Oxygen in Industrial Use plays an important role in regulating the requirements of oxygen used in the industry. It specifies the specifications, packaging, labeling and testing for oxygen that must be complied for oxygen to meet industrial standards and requirements. It is also an important guarantee for industrial safety to maintain the oxygen quality and ensure there are no oxygen related accidents.
