BS ISO 19973-5:2015提供了评估以下类型设备可靠性的测试程序: 气动阀:止回（止回）阀；先导式止回阀；梭阀；双压力阀（和功能）；单向可调流量控制阀；快速排气阀通过测试和报告测试结果的方法。一般试验条件和计算 方法见ISO 19973-1。ISO 19973-1中规定的方法适用于第一次故障，如下所示: 使用三点移动平均（3PMA）方法获得，无需修复，但不包括异常值。这些气动阀的使用寿命通常以循环次数表示。因此，每当 术语“时间”在ISO 19973的本部分中使用，该变量被理解为循环数。ISO 19973的这一部分还规定了测试设备和阈值水平，以评估 这些气动阀的可靠性。交叉引用: ISO 1219-1ISO 5598ISO 8778ISO 11727ISO 19973-1ISO 80000-1IEC 60050-191ISO 6358购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS ISO 19973-5:2015 provides test procedures for assessing the reliability of the following types of pneumatic valves:non-return (check) valves;pilot-operated non-return valves;shuttle valves;dual pressure valves (AND function);one-way adjustable flow control valves;quick-exhaust valvesby 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, as obtained with the three-points moving average (3PMA) method, without repairs, but excluding outliers.The lifetime of these pneumatic valves is usually given as a number of cycles. Therefore, whenever the term "time" is used in this part of ISO 19973, this variable is understood as a number of cycles.This part of ISO 19973 also specifies test equipment and threshold levels for tests to assess the reliability of these pneumatic valves.Cross References:ISO 1219-1ISO 5598ISO 8778ISO 11727ISO 19973-1ISO 80000-1IEC 60050-191ISO 6358All current amendments available at time of purchase are included with the purchase of this document.
