GB/T3634-1995 Industrial Hydrogen
Focussing on the use of hydrogen in industrial applications,GB/T3634-1995 is a standard issued by the China Commission for Standardization (CCS) which specifies the usage, inspection and testing of low-pressure hydrogen. The standard covers general requirements and classifications, manufacture, inspection and testing, packaging, marking and storage of hydrogen, particularly for its use as a fuel in industrial processes.
The standard specifies the three categories of “Extra-Low Pressure (< 250 kPa)”, “Low Pressure (250 to 500 kPa)” and “High Pressure (> 500 kPa)”, based on their respective working pressures. Additionally, requirements for the production of industrial hydrogen have been specified considering the impact of environmental protection.
Some of the requirements include but are not limited to the use of approved equipment and approved processes (e.g. liquefaction, distillation). The GB/T3634-1995 standard also includes regulations for the transport, storage, use and disposal of industrial hydrogen, as well as recommendations for occupational safety during its handling.
Manufacturers and users of industrial hydrogen, who comply with the provisions of the GB/T3634-1995 standard, are widely regarded as having met the relevant safety and environmental criteria. For example, gas suppliers that meet the requirements of the standard are considered to be operating within the boundaries of safe and responsible gas production, transport and handling.
In summary, the GB/T3634-1995 standard for industrial hydrogen provides detailed specifications for the production, inspection, testing, transport and handling of industrial hydrogen. Meeting the requirements of the standard helps manufacturers, suppliers and their customers to ensure the safe use of industrial hydrogen, and to minimise the impact on the environment and human health.
