ÖNORM EN 3988

Issue date: 2026 03 01

Aerospace series - Test methods for metallic materials - Constant amplitude strain-controlled low cycle fatigue testing

This document applies to uniaxial strain-controlled low cycle fatigue testing of metallic materials governed by EN aerospace standards. It defines the properties that need to be determined and the terms used in describing the tests and test pieces. It specifies the equipment, the test pieces, the method of testing and the presentation of results. It applies to testing at ambient and elevated temperatures. The purpose of this document is to ensure the comparability and reproducibility of the test results. It does not cover the evaluation or interpretation of the results. This document is restricted to the use of test pieces having a circular cross-section. In some particular cases the practice can be applied to flat test pieces. The major difficulties concern the preparation of the test pieces and their alignment in the grips.

Frequently Asked Questions about ÖNORM EN 3988

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
