Full title and description

ISO 1099:2017 — Metallic materials — Fatigue testing — Axial force-controlled method. This International Standard specifies conditions and procedures for conducting axial, constant-amplitude, force-controlled fatigue tests at ambient temperature on metallic test specimens (excluding deliberately notched specimens and specialized component tests).

Abstract

ISO 1099:2017 defines the axial force‑controlled fatigue test method used to obtain fatigue information such as the relationship between applied stress and number of cycles to failure (S–N data) for metallic materials in a given material condition (hardness, microstructure) and at various stress ratios. The standard describes specimen forms (circular and rectangular cross sections), preparation, test conditions and reporting, while excluding component testing and other specialised test forms.

Scope

This standard applies to axial, constant‑amplitude, force‑controlled fatigue tests at ambient temperature on metallic specimens without deliberately introduced stress concentrations. It covers specimen geometry (circular and rectangular sections), preparation, alignment, test procedure, test control (force), stress‑ratio specification and result reporting intended to produce S–N fatigue data for materials evaluation and comparison. Not covered are notched/component fatigue testing and other specialised test methods.

Key topics and requirements

• Definition of axial force‑controlled (load‑controlled) test method and objectives (S–N data generation).
• Specification of specimen types: circular and rectangular cross sections, preparation and surface condition.
• Test machine and alignment requirements to ensure axial loading and minimize bending.
• Control parameters: constant amplitude loading, force measurement and stress‑ratio (R) definition.
• Ambient temperature requirements and notes on environmental effects.
• Data recording, notation of material condition (hardness, microstructure), and reporting formats for fatigue results.
• Exclusions: component testing, deliberately notched specimens and specialised fatigue test forms.

Typical use and users

Used by materials testing laboratories, metallurgical researchers, mechanical engineers, product designers, quality assurance and certification bodies to determine fatigue behaviour of metallic materials, compare material batches, validate material specifications and provide input data for fatigue design and lifetime estimation.

Related standards

Standards that commonly accompany or complement ISO 1099 include ISO 12106 (axial strain‑controlled fatigue testing) and ISO 22407 (axial plane bending method), as well as other ISO documents on specimen preparation, extensometer/calibration practices and mechanical testing of metals.
