ISO 12107:2003介绍了疲劳试验的试验计划和结果数据的统计分析方法。其目的是通过高置信度和实际数量的试样来确定金属材料的疲劳性能。 它提供了一种分析各种应力水平下疲劳寿命特性的方法，使用一种可以在适当坐标系下线性近似材料响应的关系。具体而言，它涉及给定应力下的疲劳寿命，以及给定疲劳寿命下的疲劳强度。 它仅限于分析因单一疲劳失效机制而表现出均匀行为的材料的疲劳数据。 这是指与试验条件下的材料行为密切相关的试验结果的统计特性。

ISO 12107:2003 presents methods for the experimental planning of fatigue testing and the statistical analysis of the resulting data. The purpose is to determine the fatigue properties of metallic materials with both a high degree of confidence and a practical number of specimens. It provides a method for the analysis of fatigue life properties at a variety of stress levels using a relationship that can linearly approximate the material's response in appropriate coordinates. Specifically, it addresses the fatigue life for a given stress, and the fatigue strength for a given fatigue life. It is limited to the analysis of fatigue data for materials exhibiting homogeneous behaviour due to a single mechanism of fatigue failure. This refers to the statistical properties of test results that are closely related to material behaviour under the test conditions.
