Who knows the calibration standards for lever-type safety valves?

Same topic: Recently, I need to inspect such valves; they are required for use. If anyone knows the standard numbers or has relevant knowledge, please share it with me! Thank you!
No one pays attention to knowledge in this area!
You may refer to the following: Regulations on the Inspection of Pressure Vessels in the Power Industry, Guidelines for the Use of Safety Valves in Power Station Boilers, Regulations on the Safety Technical Inspection of Safety Valves, Regulations on the Safety Technical Inspection of Steam Boilers (Ministry of Labor).

The design, manufacturing, and acceptance criteria for safety valves shall comply with GB/T12243-2005
Thank you for your reply. I have read all this material; there are only regulations regarding the use of lever-type safety valves, but no detailed rules for their calibration! Also, GB/T12243-2005 (Safety valves with direct spring loading) does not contain any regulations regarding lever-type safety valves!
