GB/T stands for "Guobiao/Tuijian," which means "National Standard/Recommendation" in China. This family of standards governs a vast range of products and systems within the country. GB/T 41269-2022 is very real and highly specific.
A crucial component of the standard is the requirement for risk evaluation. This involves assessing the potential for excessive pressure and ensuring that the installed safety devices are adequate to manage this risk based on thorough analysis. 3. Special Operating Conditions The standard addresses various scenarios, including:

A safety valve is only as good as the piping leading to it. ISO 4126-9 establishes mandatory limits on pressure drop across the inlet lines. High pressure drops in an inlet line can cause the valve to "chatter"—rapidly opening and closing—which destroys the valve seating and severely compromises relief capacity. 3.
