Description (English):

ISO 20407:2017 specifies a test method for determining interfacial tensile/tensile or shear/shear cyclic fatigue properties of ceramic-ceramic, ceramic-metal, and ceramic-glass joining loaded in the constant amplitude at room temperature. Procedures for test piece preparation, test modes and rates (load rate or displacement), data collection and reporting procedures are given. ISO 20407:2017 applies primarily to ceramic materials, including monolithic fine ceramics and whisker-, fibre- or particle-reinforced ceramic composites. This test method can be used for material research, quality control, and characterization and design data-generation purposes.

Abstract

Overview

ISO 20407:2017 specifies a standardized test method for interfacial tensile and shear fatigue properties of ceramic joining under constant-amplitude cyclic loading at room temperature. It covers joints between ceramic-ceramic, ceramic-metal and ceramic-glass and is intended primarily for fine ceramics (monolithic and reinforced composites). The standard defines test-piece preparation, fixture design, loading modes (tensile/tensile and shear/shear), data collection and reporting to generate reliable cyclic-fatigue and residual-bond-strength data for research, quality control and design.

Key topics and technical requirements

Test principle: Use a cross-bonded test piece cycled at a specified average stress (σm) with constant amplitude loading (sine, triangular or trapezoidal waves) to measure cyclic fatigue life (Nf) and residual interfacial strength.
Test pieces: Rectangular bars joined to form a symmetrical cross. Recommended bar size: 4 mm × 4 mm × 12 mm; right-angle cross-sections within ±1°; parallelism tolerances specified (longitudinal faces within 0.015 mm).
Fixture and apparatus:
- Hydraulic or electromechanical fatigue machine in load-control mode; force measurement conforming to ISO 7500‑1.
- Testing fixture designed to avoid asymmetrical stresses; pressure head and supporting fixture dimensions and surface qualities specified. Fixture material recommended with elastic modulus > 200 GPa and hardness (HV) > 3 GPa.
- Micrometers to ISO 3611 for dimensional measurement.
Loading parameters:
- Minimum force usually 2–5 N; maximum force typically 70–90% of fracture load (or set per service requirement).
- Frequency, waveform and cycle count defined; cycle counting and data recording (digital recommended).
Measurement & reporting:
- Bonding area and specimen dimensions measured to 0.02 mm accuracy; arithmetic means used for calculations.
- Minimum of three valid test results required per condition.
- Record cyclic life (Nf), time to failure (tf), and residual properties; test validity criteria included.

Applications and users

ISO 20407:2017 is useful for:

Materials researchers developing or evaluating advanced ceramics and ceramic composites.
Engineers generating fatigue and design data for bonded ceramic components.
Quality-control laboratories validating joint reliability in ceramic-ceramic, ceramic-metal or ceramic-glass assemblies.
Manufacturers of electronic substrates, sensors, high-temperature components and structural ceramic parts where interfacial durability under cyclic loads is critical.

Keywords naturally targeted: ISO 20407:2017, fine ceramics, interfacial tensile fatigue, shear fatigue, ceramic joining, cyclic fatigue test method, constant amplitude loading, material characterization.
