The standard defines strict tolerances for the pressure at which the valve opens (set pressure). This tolerance varies depending on the pressure range (e.g., typically ±3% of set pressure for higher pressure valves). This precision is vital to ensure the system is protected without venting unnecessarily early. Recommend methods: GUM approach, Monte Carlo simulation for
The standard requires that materials used in safety valves must be compatible with the fluid they handle and capable of withstanding the temperatures and pressures of the system. This prevents corrosion or material failure during an emergency.
