Failure Analysis Testing Services: What’s Included & How They Work
When a product, component, or material fails — whether in the field, during manufacturing, or in qualification testing — the cost of that failure extends far beyond the immediate replacement or repair. Warranty claims, regulatory consequences, damage to customer confidence, and the risk of recurrence across an entire production lot all depend on one critical question: why did it fail?
Failure analysis testing services provide the systematic, multidisciplinary investigation needed to answer that question with scientific rigor. From initial visual examination through advanced instrumental analysis and root cause determination, professional failure analysis transforms a product failure event into actionable corrective knowledge.
What Failure Analysis Testing Services Include
A comprehensive failure analysis testing service is not a single test — it is a coordinated, sequential investigation program that draws on multiple analytical techniques, each chosen based on the failure type, material, and information already gathered. The key service elements include:
Failure Documentation and Initial Examination
Every failure analysis begins with thorough documentation. Photographs, dimensional measurements, and written descriptions of the failed component — including its service history, operating conditions, and the circumstances of failure — establish the baseline for the investigation. Visual examination under stereo optical microscopy identifies macroscopic failure features: fracture locations, deformation patterns, corrosion, discoloration, and surface damage.
Non-Destructive Testing (NDT) Methods
Before any destructive preparation, NDT methods are used to preserve evidence of failure while gathering structural information. X-ray radiography, scanning acoustic microscopy (SAM), infrared thermography, and dye penetrant inspection are commonly deployed to locate internal defects, voids, cracks, and delaminations without compromising the sample for subsequent analysis.
Mechanical Testing
Hardness testing (Rockwell, Vickers, Brinell) verifies that materials were correctly heat-treated and meet specifications. Tensile, impact, and fatigue testing on retained material or specimens cut from failed components confirms whether the mechanical properties were within specification. Mechanical test data is correlated with microstructural findings to determine whether material non-conformance contributed to failure.
Chemical Composition Analysis
Optical emission spectroscopy (OES), X-ray fluorescence (XRF), and inductively coupled plasma (ICP) techniques verify alloy composition for metallic components. Fourier transform infrared spectroscopy (FTIR) and gas chromatography-mass spectrometry (GC-MS) identify organic compounds, contamination, and degradation products in polymers and coatings. Correct material chemistry is confirmed — incorrect grade, contamination, or material substitution are identified as potential root causes.
Scanning Electron Microscopy (SEM) and EDS Analysis
SEM fractography is the centerpiece of most failure analysis investigations. High-resolution imaging of fracture surfaces, corrosion sites, and wear features identifies failure mode and initiation site. EDS elemental mapping identifies corrosion products, contaminants, and compositional anomalies at the failure origin.
Metallographic Analysis
Cross-sectional metallographic examination reveals microstructural features — grain size, phase distribution, inclusion content, decarburization, plating thickness, weld fusion quality, and heat-affected zone characteristics — that either confirm or rule out material and process-related contributors to failure.
Thermal Analysis
DSC and TGA characterize the thermal properties of polymers, adhesives, and composite matrices — identifying degradation, contamination, and improper curing or heat treatment that may have contributed to failure.
The Failure Analysis Report
A professional failure analysis testing service delivers a comprehensive written report that includes:
- Background and failure circumstances — service history, loading conditions, environmental exposure
- Testing scope and methodology — all tests performed, standards followed, instruments used
- Findings — detailed description of all analytical observations, supported by micrographs, spectra, and test data
- Root cause determination — the fundamental reason(s) for failure, clearly distinguished from contributing and direct causes
- Corrective action recommendations — specific, actionable steps to prevent recurrence
This report serves as the engineering record of the investigation and may be used to support warranty claims, regulatory submissions, legal proceedings, or internal quality improvement programs.

Frequently Asked Questions (FAQs)
What does a failure analysis testing service include? A comprehensive failure analysis testing service includes failure documentation, visual examination, non-destructive testing, chemical composition analysis, mechanical testing, SEM/EDS fractography, metallographic analysis, thermal analysis, root cause determination, and a formal written report with corrective action recommendations.
What is the first step in a failure analysis investigation? The first step is thorough failure documentation and initial visual examination — establishing the failure circumstances, service history, and macroscopic failure features before any destructive preparation is performed.
Why must non-destructive testing precede destructive analysis in failure analysis? NDT techniques preserve the sample's integrity and capture failure evidence — internal cracks, voids, delaminations — that would be destroyed by cutting, polishing, or etching. NDT findings also guide the most informative application of destructive methods.
What information should a failure analysis report contain? A failure analysis report should document the failure background, complete testing methodology, all analytical findings (with supporting images, spectra, and test data), a root cause determination that distinguishes direct from fundamental causes, and specific, actionable corrective action recommendations.
How does Infinita Lab manage multi-technique failure analysis programs? Infinita Lab assigns a single point of contact (SPOC) to coordinate all required testing techniques — SEM, chemical analysis, mechanical testing, NDT, and thermal analysis — across its nationwide laboratory network, providing integrated, fast, and confidential failure analysis management.
