GB/T 33440-2021 specifies the general requirements for assessing the interchangeability of natural gases from different sources, ensuring that changes in gas composition do not adversely affect the performance, safety, or emissions of end-use appliances. It is applied in the natural gas supply chain, including pipeline operators, gas distributors, and appliance manufacturers in China, to evaluate compatibility when blending or switching gas supplies. The standard is used in both laboratory testing and field applications to maintain consistent combustion characteristics for residential, commercial, and industrial gas equipment.
