本标准适用于阀门设计的分类，并提供了阀杆和阀体密封的测试方法。不用于生产测试，不包括控制阀。试验方法的结果应根据以下选择将阀门设计分类为性能水平:试验温度；额定压力；泄漏（浓度，百万分之几）；机械循环（循环次数）；热循环次数；以及对密封件的调整和/或调整次数。 本标准规定的试验方法仅适用于具有以下阀杆运动设计的阀门:旋转和上升；旋转和不上升；不旋转和上升。该分类仅适用于1.2中测试的阀杆运动设计。特定阀门的试验结果可用于根据以下指南将分类扩展至其他阀门:当阀杆和阀体密封直径在+或+范围内时，适用于具有相同阀杆和阀体密封材料、几何形状和负载特性的阀门- 25%的测试直径；至阀门，否则以前为S93。00.01-1999. 相同，适用于低于测试温度的环境温度；适用于压力等级较低的其他相同阀门。用于真空应用的阀门不在本标准范围内。本标准的目的是建立一个统一的流程，以确保手动和自动开关阀使用统一的方法进行测试，并满足用户在遵守挥发性有机化合物（VOC）无组织排放要求方面的需求。 本试验方法不适用于合格或不合格标准。

This standard applies to the classification of valve design and provides the methods for the testing of valve stem(s) and body seal(s). Not intended for production testing and excludes control valves. The results of the test methods shall classify valve designs to performance levels per the following selections: test temperature; pressure rating; leakage (concentration, parts per million); mechanical cycles (number of); thermal cycles (number of); and adjustment(s) to seal(s) and/or number of adjustments. Test methods per this Standard shall apply only to valves with the following stem motion designs: rotating and rising; rotating and non-rising; non-rotating and rising. The classification shall apply only to the stem(s) motion design of 1.2, which is tested. The test results of a particular valve may be used to extend the classification to other valves per the following guidelines: to valves with identical stem(s) and body seal(s) material, geometry, and loading characteristics, when the stem(s) and body seal(s) diameters are within +or- 25% of the tested diameters; to valves otherwise Formerly S93.00.01-1999. identical, which are applied below the tested tempertaure, down to ambient temperature; to valves otherwise identical, which are of a lower pressure rating. Valves intended for vacuum service are beyond the scope of this standard. The purpose of this standard is to establish a uniform process for assuring that manual and automated on-off valves are tested using uniform methods and will meet user needs in complying with volatile organic compounds (VOC) fugitive emissions requirements. The test method is not intended to be a pass-fail criteria.
