本标准适用于阀体、阀盖、盖板和底部法兰由碳钢、低合金和高合金钢（不锈钢）、镍基合金、铸铁和球墨铸铁制成的控制阀。本标准规定了阀门制造商对控制阀进行标准静水压壳体试验的要求和定义，以证明阀门承压部件的结构完整性和密封性，包括任何封闭部件，如阀体至阀盖接头，但不包括填料、波纹管或其他移动密封件，以及填料泄漏/吹扫/排气口连接。波纹管或类似的移动阀杆密封件在组装后可在阀门制造商和买方商定的压力下进行压力测试。 本标准的要求不包括气动和液压执行机构和调节器。

This standard applies to control valves having bodies, bonnets, cover plates, and bottom flanges made of carbon steel, low alloy and high alloy (stainless) steel, nickel-base alloy, cast iron, and ductile iron. This standard establishes requirements and definitions for standard hydrostatic shell testing of control valves by the valve manufacturer to prove the structural integrity and leak tightness of the valves' pressure retaining parts, including any closure parts such as the valve body to bonnet joint, but excluding packings, bellows or other moving seals, and packing leakoff/purge/vent port connections. Bellows or similar moving stem seals may be pressure tested after assembly at a pressure to be agreed upon by the valve manufacturer and the purchaser. The requirements of this standard do not cover pneumatic and hydraulic actuators and regulators.
