Изделия крепежные с резьбой. Испытания на сопротивление усталости при осевой нагрузке. Методы испытаний и оценка результатов
Название (англ.):
Threaded fasteners; axial load fatigue testing; test methods and evaluation of results
Описание (англ.):
Specifies the conditions for carrying out the tests as well as recommendations for the evaluation of the results. Unless otherwise agreed, the tests are of the fluctuating tension type and are carried out at room temperature. The influence of the compliance of clamped parts on the strain of the fastener is not taken into account. Thetest results can be influenced by the test conditions. For this reason, minimum requirements are specified to reduce this effect. In addition, calibration and centring control methods for the testing apparatus are included.
