16 Gas Standards Revised
On April 1, it was revealed by the Secretariat of the National Gas Standardization Technical Committee that 16 national gas standards have successfully passed an online voting process involving 55 members. This development is expected to significantly contribute to regulating the gas market, enhancing gas quality, and accelerating the integration of Chinese gas industry standards with global practices.
The revised national gas standards are updated annually in line with international standard changes and the evolving needs of China’s gas sector. After a thorough online review and voting process, several key standards were updated, including "Industrial Oxygen," "Industrial Nitrogen," "Pure Nitrogen, High-Purity Nitrogen, and Ultra-Pure Nitrogen," "Pure Oxygen, High-Purity Oxygen, and Ultra-Pure Oxygen," as well as standards related to the determination of hydrogen, carbon monoxide, carbon dioxide, and hydrocarbons in gases. Additional updates covered topics such as "Gas Traces Determination by Hydrogen Gas Chromatography," "Comparison of Measurement and Calibration of Gas Analytical Calibration Mixtures," "Gas Analysis Vocabulary," and specific standards for medical and aviation breathing oxygen, electronic-grade nitrogen, oxygen, and hydrogen, along with specialized gases like phosphine and sulfur hexafluoride used in the electronics industry.
Wang Shaonan, Secretary General of the Gas Standardization Committee and Director of the Gas Standardization Research Institute at Southwest Chemical Research and Design Institute, emphasized that the gas industry plays a vital role across multiple sectors, including food and beverage, healthcare, metallurgy, chemicals, microelectronics, semiconductors, optical fibers, and aerospace. He noted that gas standards are crucial for market access and are now integral to the broader market rules system.
According to Wang, while progress has been made, there is still a need to strengthen alignment with international standards, improve the review and calibration of gas standard samples, and enhance training for personnel involved in gas product inspections. These efforts will ensure China's gas industry remains competitive on the global stage.
