ASD-STAN PREN 3874 PDF

This standard applies to constant amplitude force-controlled low cycle fatigue (LCF) testing of metallic materials governed by EN Aerospace standards. It defines the mechanical properties that may need to be determined, the equipment, test pieces, methodology of test and presentation of results.

It applies to uniaxially loaded tests carried out on plain or notched test pieces under ambient and elevated temperatures. IT is not intended to cover the testing of more complex test pieces, full scale components or structures, although the methodology could well be adopted to provide for such tests.

The purpose of this specification is to ensure the comparability and reproducibility of the test results. It does not cover the evaluation or interpretation of the results
