Introduction This standard covers the requirements and method for evaluating the performance of valves when they are exposed to defined fire conditions. The performance requirements establish limits of acceptability of a valve regardless of size or pressure rating. The burn period has been established to represent the maximum time si ns su sassn pue sam ui sial pinb o uns peu ospu e si wss e u expected in a process plant when a fire is detected and pumps are shut down. In this case the source of pressure approximated by this lower test pressure. In production facilities valves are typically of a higher rating and the pressure source is not easily reduced when a fireisetected.Therforefrallthervalvesthe test pressureduring thebussetatahigher value tobettr simulate the expected service conditions in these facilities. Use of this standard assumes that the execution of its provisions is entrusted to appropriately qualified and experienced personnel because it calls for procedures that and does not absolve the user from legal obligations relating to health and safety at any stage of the procedure.
