ISO 22514-3:2008规定了进行短期性能研究时应采取的步骤，这些研究通常在考虑重复性条件下连续生产零件的机器上进行。根据数据产生的模式，或者如果机器上的运行（生产项目的速度）数量较低，要分析的观察值的数量将有所不同。如果产生的样本量小于30个观察值，则不建议使用这些方法。描述了用于处理数据和执行计算的方法。此外，还描述了机器性能指标和机器性能研究结束时需要采取的措施。ISO 22514-3:2008不适用于研究期间预计存在刀具磨损模式，也不适用于观测值之间存在自相关的情况。机器捕获数据（有时一分钟内收集数千个数据点）的情况不适用于ISO 22514-3:2008的应用。

ISO 22514-3:2008 prescribes the steps to be taken in conducting short-term performance studies that are typically performed on machines where parts produced consecutively under repeatability conditions are considered. The number of observations to be analysed will vary according to the patterns the data produce, or if the runs (the rate at which items are produced) on the machine are low in quantity. The methods are not recommended where the sample size produced is less than 30 observations. Methods to be used for handling the data and carrying out the calculations are described. In addition, machine performance indices and the actions required at the conclusion of a machine performance study are described.ISO 22514-3:2008 is not applicable when tool wear patterns are expected to be present during the duration of the study, nor if autocorrelation between observations is present. The situation where a machine has captured the data, sometimes thousands of data points collected in a minute, is not considered suitable for the application of ISO 22514-3:2008.
