ISO 12110-1:2013确立了实验室试样在一系列循环下进行疲劳试验的一般原则，这些循环的振幅随循环而变化。 这种循环序列被称为加载时间历程（见3.7），通常是从提交给真实工作载荷的部件或结构上进行的加载测量得出的。 工作负荷记录的详细描述与每个实验室或工业部门有关，因此不在ISO 12110-1:2013的范围内。 ISO 12110的两个部分旨在设定要求，并就如何进行变幅疲劳试验提供一些指导，以便在考虑疲劳数据典型分散性的情况下，产生一致的结果进行比较。实现这一点将有助于设计师关联从各种来源获得的模型和实验数据。 由于ISO 12110-1:2013主要涉及加载时程和控制信号的生成，人们预计它可能适用于应变或疲劳裂纹扩展速率控制加载条件以及力控制加载条件。这在理论上是正确的，但当将本文件应用于除力控制加载模式以外的加载模式时，可能会采取预防措施。 ISO 12110-1:2013涉及力控制模式下的变幅载荷，该模式对应于出版之日全球进行的大多数变幅疲劳试验。 ISO 12110-1:2013适用于在许多情况下对应于单轴载荷的单致动器加载模式。 本文件中提及的变幅载荷时间历程是确定性的；这就是ISO 12110的原因- 1:2013涉及变幅荷载，而非随机荷载。 以下问题不在ISO 12110-1:2013的范围内，因此将不予解决:隔离过载或欠载的恒幅试验；大型组件或结构的测试；与温度/时间相互作用相关的腐蚀、蠕变等环境效应会导致频率和波形效应；多轴加载。

ISO 12110-1:2013 establishes general principles for fatigue testing of laboratory specimens under a sequence of cycles the amplitude of which varies from cycle to cycle. This sequence of cycles is called loading time history (see 3.7) and is usually derived from loading measurements performed on components or structures submitted to true service loadings. Detailed description of service loads recording is relevant to each laboratory or industrial sector and is therefore outside the scope of ISO 12110-1:2013. The aim of the two parts of ISO 12110 is to set requirements and give some guidance on how to perform a variable amplitude fatigue test in order to produce consistent results for comparison purposes taking into account the typical scatter of fatigue data. Achieving this should help designers to correlate models and experimental data obtained from various sources. Since ISO 12110-1:2013 involves mainly loading time histories and control signal generation, one expects it might be applied to strain or fatigue crack growth rate controlled loading conditions as well as to force-controlled loading conditions. This is theoretically true but precautions may be taken when applying this document to loading modes other than force-controlled loading mode. ISO 12110-1:2013 relates to variable amplitude loading under force control mode which corresponds to most of the variable amplitude fatigue tests performed worldwide at the date of publication. ISO 12110-1:2013 applies to the single actuator loading mode which corresponds to uniaxial loading in many cases. The variable amplitude loading time histories referred in this document are deterministic; that is why ISO 12110-1:2013 deals with variable amplitude loading instead of random loading. The following issues are not within the scope of ISO 12110-1:2013 and therefore will not be addressed: constant amplitude tests with isolated overloads or underloads; tests on large components or structures;environmental effects like corrosion, creep linked to temperature/time interactions leading to frequency and waveform effects; multiaxial loading.
