What are some common fatigue testing standards for materials?

1 ASTM standards

ASTM International is a global organization that develops and publishes voluntary consensus standards for various fields, including materials science. In particular, ASTM has over 12,000 standards related to fatigue testing of metals, polymers, composites, ceramics, and other materials. Examples of these standards include ASTM E466 for conducting force controlled constant amplitude axial fatigue tests of metallic materials, ASTM E647 for measuring fatigue crack growth rates, ASTM D3479 for tension-tension fatigue of polymer matrix composite materials, and ASTM C1368 for determining slow crack growth parameters of advanced ceramics by constant stress-rate flexural testing. These standards provide detailed procedures, equipment, terminology, and reporting requirements to ensure consistency, accuracy, and comparability of fatigue test results across different laboratories and industries.

2 ISO standards

ISO is an international organization that develops and publishes standards for various aspects of technology, business, and society. With over 23,000 standards, ISO also provides guidelines for fatigue testing of materials. Examples include ISO 12106: Metallic materials - Fatigue testing - Axial-strain-controlled method, ISO 12107: Metallic materials - Fatigue testing - Statistical planning and analysis of data, ISO 13003: Fibre-reinforced plastics - Determination of fatigue properties under cyclic loading conditions, and ISO 23146: Fine ceramics (advanced ceramics, advanced technical ceramics) - Test method for fracture toughness of monolithic ceramics at room temperature by the surface crack in flexure (SCF) method. These standards are designed to help harmonize the methods and criteria for fatigue testing across different countries and regions, providing general principles, recommendations, and best practices.

3 SAE standards

SAE International is a professional association and standards development organization for the engineering of mobility systems, such as automotive, aerospace, and marine. SAE has over 35,000 standards, some of which are applicable for fatigue testing of materials. For example, SAE J1099 provides a standard practice for fatigue testing of automotive components, while SAE J1739 outlines potential failure mode and effects analysis in design (Design FMEA) and manufacturing and assembly processes (Process FMEA). Furthermore, SAE ARP1185 presents fatigue test procedures for aircraft wheel design methodology and SAE AIR5381 describes fatigue crack growth testing of titanium alloys. These SAE standards provide specific guidance, requirements, and examples for fatigue testing of materials in the context of mobility systems; thus helping to address the challenges and needs of engineering complex and dynamic systems that are exposed to fatigue loading.

4 Why are fatigue testing standards important?

Fatigue testing standards are important for several reasons. First, they help to ensure the quality and reliability of materials and products that are subject to fatigue loading in various applications, such as aerospace, automotive, biomedical, and energy. Second, they help to facilitate the communication and collaboration among researchers, engineers, manufacturers, and customers who are involved in the development, testing, and use of materials and products. Third, they help to advance the knowledge and innovation in the field of materials science by providing a common framework and reference for fatigue testing. Fatigue testing standards are essential tools for the design, evaluation, and improvement of materials and products that can withstand fatigue loading and enhance performance, safety, and durability.
