prEN 3874

This document applies to constant-amplitude force-controlled low-cycle fatigue (LCF) testing of metallic materials governed by EN Aerospace standards. The document defines the mechanical properties that need to be determined, the equipment, test pieces, methodology of test and presentation of results.
The document applies to uniaxially loaded tests carried out on plain or notched test pieces under ambient and elevated temperatures. The document does not 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 document is to ensure the comparability and reproducibility of the test results. The document does not cover the evaluation or interpretation of the results.
