Failure Analysis Laboratory: A Buyer's Guide
Why evidence preservation comes before any testing, what a real root-cause finding looks like, and the buyer checklist for a failure investigation.
A failure analysis laboratory investigates why a material, component, or product failed in service or testing, combining materials-testing methods (metallography, fractography, chemical analysis) with root-cause engineering to produce a report identifying the failure mechanism, often for warranty disputes, product recalls, insurance claims, or litigation support.

The buyer problem
When a part breaks, a product is recalled, or an insurance claim hinges on why something failed, the buyer needs a lab that can preserve evidence properly, run the right combination of destructive and non-destructive methods to find the actual failure mechanism (not just describe the damage), and produce a report and expert opinion that will hold up under cross-examination if the matter goes to litigation.
What a failure analysis laboratory: a buyer's guide does
A failure analysis lab receives a failed component (often the only physical evidence available), documents its as-received condition before any destructive testing, and combines visual/fractographic examination, metallography, chemical analysis, and mechanical testing to determine the root-cause failure mechanism (fatigue, overload, corrosion, manufacturing defect, material substitution), then reports findings with photographic and data evidence.
Methods and techniques
- Fractography and scanning electron microscopy (SEM)
- Metallography and microstructure examination
- Chemical composition verification against spec
- Corrosion mechanism identification
- Fatigue striation analysis
- Non-destructive examination prior to sectioning (to preserve evidence)
What to verify before you retain
- Evidence preservation protocol. Confirm the lab documents the part's as-received condition (photos, non-destructive exam) before any cutting or destructive testing begins — evidence destroyed without documentation can be excluded or discredited later, especially in litigation.
- Expert witness experience, if relevant. If the failure may lead to litigation or an insurance dispute, confirm the analyst has actually testified or been deposed before, not just performed lab work — courtroom credibility is a different skill than bench work.
- Root-cause methodology, not just damage description. Ask the lab to describe their root-cause methodology up front; a lab that only describes what broke without identifying why (the actual failure mechanism) hasn't delivered a complete failure analysis.
- Sample retention after the report. Confirm how long the lab retains the failed part and any sectioned samples after the report is issued, in case a second opinion or additional testing is needed later.
Questions to put in your RFP
- What is your protocol for documenting a part's condition before any destructive testing?
- Has your analyst provided expert witness testimony or deposition on a failure analysis before?
- What is your typical timeline from receipt to a complete root-cause report?
- Will your report include a stated root-cause mechanism, or only a description of the damage observed?
- How long do you retain the failed part and sectioned samples after the report is delivered?
- Can you provide a redacted sample report so we can review your documentation standard?

Failure Analysis Laboratory: A Buyer's Guide: buyer FAQ
What's the difference between materials testing and failure analysis?
Materials testing typically confirms whether a sample meets a known specification. Failure analysis investigates an unknown: why a specific part failed, often using the same underlying test methods (metallography, chemical analysis) but aimed at determining a root-cause mechanism rather than a pass/fail result.
Why does evidence preservation matter before testing starts?
Many destructive test methods used to determine failure mechanism (sectioning, etching) permanently alter or consume the part. If the as-received condition isn't documented first, and especially if the matter later becomes a warranty dispute or lawsuit, the physical evidence and its documentation can be challenged or excluded.
Do I need a lab with expert-witness experience even if I don't expect litigation?
Not necessarily, but if there's any realistic chance of a warranty dispute, insurance claim, or lawsuit, choosing a lab whose analysts have prior deposition or testimony experience up front avoids having to redo the analysis with a different, litigation-ready lab later.
