标准范围

ISO 10771规定了在持续稳定循环内压载荷下对液压流体动力系统中使用的部件的承压外壳进行疲劳试验的方法。ISO 10771仅适用于由金属制成、在排除蠕变和低温脆化的温度下运行、仅承受压力诱导应力、不受腐蚀或其他化学作用导致的强度损失的部件承压外壳，可能包括垫圈、密封件和其他非金属部件；然而，这些不被视为被测试的承压外壳的一部分。

ISO 10771 specifies a method of fatigue testing the pressure-containing envelopes of components used in hydraulic fluid power systems under sustained steady cyclic internal pressure loads.ISO 10771 is only applicable to component pressure-containing envelopes that are manufactured from metals, are operated at temperatures that exclude creep and low-temperature embrittlement, are only subjected to pressure-induced stresses, are not subjected to loss of strength due to corrosion or other chemical action and may include gaskets, seals and other non-metallic components; however, these are not considered part of the pressure-containing envelope being tested.
