What is EN ISO 15606: 2018?

EN ISO 15606: 2018 is an international standard that provides guidelines for determining the fatigue strength of metallic materials. It is specifically focused on high-cycle fatigue, which refers to cyclic loading that involves more than 10^4 to 10^6 cycles before failure.

Importance of EN ISO 15606: 2018

This standard plays a crucial role in ensuring the reliability and safety of various applications where fatigue failure can have severe consequences, such as components in aircraft, automobiles, and infrastructure. By providing a standardized method for fatigue testing and evaluation, it facilitates the comparison of different materials and helps engineers make informed decisions in material selection and design optimization.

Main Provisions

EN ISO 15606: 2018 defines various aspects related to fatigue testing and analysis. It specifies the requirements for test specimens, loading conditions, and measurement techniques. The standard also outlines the procedures for establishing and validating S-N curves, which represent the relationship between stress amplitude (S) and number of cycles to failure (N). Additionally, it provides guidelines for interpreting test results and estimating fatigue strengths under different service conditions.

New Features in EN ISO 15606: 2018

The 2018 edition of EN ISO 15606 brings some notable improvements compared to its previous versions. It introduces additional guidance on statistical analysis methods and considers the influence of various factors, such as temperature, surface finish, and specimen size. Moreover, the standard addresses the growing demand for reliable fatigue data by incorporating recommendations for data generation through specimen pooling and using probabilistic approaches for estimation.
