General Introduction

Precision Testing for Fatigue Strength and Service Life

Electronic fatigue testing machines are designed to evaluate how materials and components perform under repeated cyclic loading. They help determine fatigue strength, endurance limit, deformation behavior, and fatigue life by simulating real working conditions in a controlled testing environment. 


Our electronic fatigue testing machine is suitable for a wide range of applications, including metals, polymers, composite materials, medical devices, flexible electronics, consumer products, and small structural parts. United Test’s own fatigue page already positions this product family across biomedical, electronics, plastics, consumer goods, automotive, and aerospace testing. 


Key Testing Capabilities

Electronic Fatigue Testing Machine supports cyclic tensile testing, compression fatigue testing, low-cycle testing, and durability evaluation under repeated loads. Test data can be used to generate S-N curves and assess how a specimen behaves before failure under specific loading conditions.


 Why Choose an Electronic Fatigue Testing Machine

Compared with conventional hydraulic systems, electronic or electrodynamic fatigue testers are often promoted for clean operation, energy efficiency, precise measurement, and smooth control. Leading manufacturers also highlight low operating cost, high accuracy, and the ability to perform both static and dynamic tests in a compact footprint.


How It Works: 
Electronic Fatigue Testing Machine applies cyclic loads to a specimen via a servo-controlled actuator. The controller precisely regulates load magnitude, frequency, and waveform while monitoring deformation. Data is recorded to plot S-N curves (stress vs. cycles to failure) or determine fatigue life under specific conditions.

ASTM D3166 Complete Guide to Adhesive Shear Fatigue Testing

ASTM D3166 — Standard Test Method for Fatigue Properties of Adhesives in Shear by Tension Loading (Metal/Metal)

ASTM D3166 is a standardized laboratory method for measuring the fatigue strength of adhesives in shear under cyclic tensile loading. It uses a single-lap-joint metal specimen and applies a sinusoidal axial load repeatedly until the bond fails. The result is an S-N curve (stress vs. logarithm of cycles), from which the "fatigue strength at 10 million cycles" is designated as the key design value. 

When structural adhesives replace welding or mechanical fasteners in aerospace, automotive, and industrial assemblies, a single question decides whether the bond will survive millions of load cycles: how long can the adhesive resist repeated shear stress before it fails?    

ISO 9664 Shear Fatigue Testing of Adhesives

ISO 9664 – Adhesives – Test methods for fatigue properties of structural adhesives in tensile shear

ISO 9664 defines standardized cyclic tensile-shear fatigue testing procedures to evaluate the fatigue strength of structural adhesives bonded on metal substrates. Critical caveat: test results are joint-system dependent (affected by specimen geometry) and cannot be directly used for structural design calculations, only for material comparative characterization. 

ISO 7206-4, ISO 7206-6: Fatigue testing of femoral stem and femoral neck of hip prostheses

ISO 7206‑4 and ISO 7206‑6 are key international standards defining fatigue endurance tests for stemmed femoral components of partial and total hip joint prostheses. ISO 7206‑4 evaluates the femoral stem under simulated proximal loosening; ISO 7206‑6 evaluates the femoral neck under well‑fixed, normal in‑vivo loading. 

ASTM F1798 Spinal Implant Subassembly Static and Fatigue Testing System

ASTM F1798 provides standardized methods for mechanically testing the interconnections within spinal implant systems. It is for evaluating the uniaxial static/fatigue strength and loosening resistance of interconnection mechanisms in spinal arthrodesis implant subassemblies, providing a standardized way to characterize mechanical performance of connections like rod-clamp, screw-rod, and hook-rod assemblies. It is critical for design validation, regulatory compliance, and clinical safety in the spinal implant industry.

ISO 13003 Fatigue Testing of Fibre-Reinforced Plastic Composites

When fibre-reinforced plastic composites replace metals in aircraft structures, wind turbine blades, automotive components, and marine vessels, engineers must answer a critical question: how many millions of constant-amplitude load cycles can a composite laminate survive before fatigue failure? ISO 13003:2003 — Fibre-reinforced plastics — Determination of fatigue properties under cyclic loading conditions — is the internationally recognized standard that answers this question with quantitative, reproducible data.


ISO 28580 Wheel Radial Load Fatigue Testing for Methods of measuring rolling resistance Single point test Passenger car truck, bus and motorcycle

ISO 28580 Passenger car truck, bus and motorcycle tyres — Methods of measuring rolling resistance Single point test Standard specifies methods for measuring rolling resistance, under controlled laboratory conditions, for new pneumatic tyres designed primarily for use on passenger cars, trucks, buses and motorcycles. The relationship between values obtained and the fuel economy of the vehicle is undetermined, and such values are not intended to be used to indicate levels of performance or quality.


This International Standard applies to all passenger car, truck, bus and motorcycle tyres. Measurement of tyres using this method enables comparisons to be made between the rolling resistance of new tyres when they are free-rolling straight ahead, in a position perpendicular to the drum outer surface, and in steady-state conditions. In measuring tyre rolling resistance, it is necessary to measure small forces in the presence of much larger forces. It is, therefore, essential that equipment and instrumentation of appropriate accuracy be used.

ISO 16525-5 Test: Definitive Guide to Shear Fatigue Testing of Isotropic Electrically Conductive Adhesives

ISO 16525-5 — Adhesives — Test methods for isotropic electrically conductive adhesives — Part 5: Determination of shear fatigue

In the electronics industry, isotropic electrically conductive adhesives (ICAs) have become a critical interconnection technology — replacing traditional solder in applications ranging from semiconductor die attachment to flexible printed circuits. But here's the challenge: these conductive joints must survive millions of thermal and mechanical cycles while maintaining both their mechanical integrity and electrical continuity. 

ISO 16525-5 specifies test methods using miniature specimens to measure the shear fatigue of a glued joint composed of isotropic electrically conductive adhesives and rigid adherends under specified conditions.

Unlike conventional structural adhesive fatigue tests (e.g., ASTM D3166), ISO 16525-5 is uniquely designed for conductive adhesives in electronic assemblies — where the joint must simultaneously maintain mechanical shear strength and stable electrical resistance throughout its service life.

ASTM D3479 Tension-Tension Fatigue of Polymer Matrix Composites

ASTM D3479 — Standard Test Method for Tension-Tension Fatigue of Polymer Matrix Composite Materials

ASTM D3479 determines the fatigue behavior of polymer matrix composite materials subjected to tensile cyclic loading. It answers the question with quantitative, reproducible data that when polymer matrix composites (PMCs) replace metals in aircraft wings, wind turbine blades, automotive structures, and sporting goods, engineers face a critical question: how many millions of tensile load cycles can a composite laminate survive before fatigue failure?
