标准范围

ISO 19973-2:2007提供了通过试验确定气动方向控制阀可靠性的试验程序，以及根据ISO 19973-1中提供的一般试验条件和计算方法报告试验结果的方法。气动和电动气动方向控制阀的使用寿命通常以循环次数表示。因此，当ISO 19973-2:2007中使用术语“时间”时，该变量被理解为周期。ISO 19973-2:2007还规定了用于确定气动方向控制阀可靠性的试验设备和阈值水平。

ISO 19973-2:2007 provides test procedures for determining the reliability of pneumatic directional control valves by testing and the methods of reporting the results of testing according to the general test conditions and the calculation method provided in ISO 19973-1.The lifetime of pneumatic and electro-pneumatic directional control valves is usually given as a number of cycles. Therefore, whenever the term "time" is used in ISO 19973-2:2007, this variable is understood as cycles.ISO 19973-2:2007 also specifies test equipment and threshold levels for tests to determine the reliability of pneumatic directional control valves.
