标准范围

ISO/TR 14345:2012给出了在中循环和高循环状态下焊接部件恒幅或变幅载荷下疲劳试验的最佳实践指南，对应于产生不超过屈服的标称应力的施加载荷。应变控制下的低周疲劳试验未具体涵盖，尽管相同的试样可适用于低周或高周疲劳试验。还包括焊接试样的制造和制备过程中涉及的不同步骤，以及试验结果的最终展示和评估。ISO/TR 14345:2012不包括腐蚀或高温疲劳试验。

ISO/TR 14345:2012 gives guidance on best practice for fatigue testing under constant- or variable-amplitude loading of welded components in the medium- and high-cycle regimes, corresponding to applied loading that results in nominal stresses that do not exceed yield. Low-cycle fatigue testing under strain control is not specifically covered, although the same test specimens can be suitable for either low- or high-cycle fatigue testing. The different steps involved in the manufacture and preparation of the welded specimens and the final presentation and evaluation of the test results are also covered.ISO/TR 14345:2012 does not cover corrosion or high-temperature fatigue testing.
