标准范围

ISO19973-3:2007提供了通过测试确定带有活塞杆的气缸可靠性的测试程序，以及报告测试结果的方法。ISO 19973第1部分中提供的一般试验条件和计算方法适用于未经维修的首次故障，但不包括异常值。气缸的使用寿命通常以循环次数或公里为单位。因此，每当ISO19973-3:2007本部分中使用术语“时间”时，该变量应理解为周期或公里。ISO19973-3:2007还规定了测试设备和阈值水平，以确定带有活塞杆的气缸（均为单活塞杆）的可靠性-表演和双重表演。ISO19973-3:2007适用于符合ISO 6430、ISO 6432、ISO 15552和ISO 21287的气动活塞杆气缸；但是，不符合这些国际标准但在相同工作条件范围内使用的气动活塞杆气缸，可以按照ISO19973-3:2007中定义的等级之一进行测试。有必要在试验报告中记录与ISO19973-3:2007的任何偏差。

ISO19973-3:2007 provides test procedures for determining reliability of pneumatic cylinders with piston rod by testing and the methods of reporting the results of testing. The general test conditions and the calculation method provided in Part 1 of ISO 19973 apply to the first failure without repairs, but exclude outliers.The lifetime of pneumatic cylinders is usually given in number of cycles or in kilometres. Therefore, whenever the term "time" is used in this part of ISO19973-3:2007, this variable is to be understood as cycles or kilometres.ISO19973-3:2007 also specifies test equipment and threshold levels for tests to determine the reliability of pneumatic cylinders with piston rods, both single-acting and double-acting.ISO19973-3:2007 is intended to be applied to pneumatic piston rod cylinders that conform to ISO 6430, ISO 6432, ISO 15552 and ISO 21287; however, pneumatic piston rod cylinders that do not conform to these International Standards but are used in the same range of operating conditions can be tested in accordance with one of the classes defined inISO19973-3:2007. It is necessary that any deviation from ISO19973-3:2007 be documented in the test report.
