标准范围

ISO 19973-4:2007提供了通过测试评估气动压力调节器可靠性的测试程序和报告测试结果的方法。ISO 19973-1中提供了一般试验条件和计算方法。ISO 19973-1中规定的方法适用于未经修复的首次故障，但不包括异常值。ISO 19973-4:2007适用于手动调节和遥控压力调节器，包括泄压和非泄压。ISO 19973-4:2007不适用于永久性排气的压力调节器。ISO 19973-4:2007还规定了用于评估气动压力调节器可靠性的试验设备和故障标准（阈值水平）。

ISO 19973-4:2007 provides test procedures for assessing the reliability of pneumatic pressure regulators by testing and the methods of reporting the results of testing. General test conditions and the calculation method are provided in ISO 19973-1. The methods specified in ISO 19973-1 apply to the first failure without repairs, but exclude outliers.ISO 19973-4:2007 applies to manually adjustable and remote-piloted pressure regulators, both relieving and non-relieving. ISO 19973-4:2007 does not apply to pressure regulators that have a permanent bleed.ISO 19973-4:2007 also specifies test equipment and failure criteria (threshold levels) for tests to assess the reliability of pneumatic pressure regulators.
