Testing Expert Witnesses

Testing results often determine whether products, materials, and systems are accepted, certified, recalled, or paid for, so disputes over testing carry significant commercial consequences. Manufacturers, suppliers, laboratories, certification bodies, and buyers litigate over whether products met specifications, whether testing protocols were appropriate, and whether laboratory results were reliable. Regulatory and false advertising matters may depend on whether performance or safety claims were substantiated by adequate testing. The central issue is usually whether the testing actually measured what the parties believed it measured.

A testing expert helps attorneys evaluate test design, execution, and interpretation. The expert can review test methods, sampling plans, equipment calibration, laboratory records, chain of custody, and data analysis, measuring them against applicable standards from organizations such as ASTM International, ISO, and UL, and laboratory quality requirements such as ISO/IEC 17025. The expert can also design and conduct independent testing to verify or challenge results. That analysis frames liability and causation by establishing whether products or systems met requirements and supports damages tied to nonconformance, recall, or lost business.

Credible testing experts understand both the science behind a test and the practical realities of running a laboratory. Round Table Group can identify materials scientists, test engineers, metrologists, and laboratory directors, including professionals whose careers involved organizations such as UL, NIST, and Intertek, as well as university engineering laboratories and manufacturers' quality organizations. Their experience allows them to explain to a tribunal why a test is or is not reliable and what its results mean. Our more than 75,000 expert searches for litigators help us match the product and test methods in your case with a qualified expert.

Kinds of Cases We Work On

Round Table Group helps our clients find a wide variety of Testing expert witnesses for cases like:

01

Software Testing Vendor Sued Over Missed Defects

A financial technology company sued its outsourced software testing vendor after a critical payment processing bug the vendor's test suite failed to catch caused transaction failures across a major product release. We identified experts with experience in software quality assurance testing methodology, financial technology systems testing standards, and outsourced testing contract performance. The expert's test-coverage audit found the suite omitted a required edge-case scenario, supporting the company's breach-of-contract claim.
02

Certification Lab Sued Over Faulty Product Approval

An appliance manufacturer sued an independent product testing and certification laboratory after a line of certified electric heaters was recalled for an overheating defect the lab's safety testing protocol should have detected. We identified experts with experience in consumer product safety testing standards, electrical appliance certification protocols, and testing laboratory quality assurance. The expert found the lab had skipped a required thermal stress test cycle, supporting the manufacturer's claim.
03

Non-Destructive Testing Firm Faces Pipeline Weld Claim

A pipeline operator sued its non-destructive testing contractor after a weld defect went undetected during a required inspection program, later contributing to a leak that forced a multi-day section shutdown. We identified experts with experience in non-destructive weld testing methodology, pipeline integrity inspection standards, and industrial inspection quality control. The expert's review of radiographic images found a visible flaw the inspector's report had not flagged, supporting the operator's claim.
04

Calibration Lab Sued Over Instrument Drift Failure

A pharmaceutical manufacturer sued its instrument calibration service provider after a batch of temperature sensors used in a sterile manufacturing process were found to have drifted out of tolerance months before the provider's next scheduled visit. We identified experts with experience in laboratory instrument calibration standards, pharmaceutical manufacturing quality systems, and calibration interval risk assessment. The expert found the provider's calibration interval did not match the manufacturer's recommended schedule, supporting the breach-of-contract claim.
05

Clinical Lab Sued Over Inaccurate Test Results

A hospital system sued a reference clinical laboratory after a batch of diagnostic test results were found to be systematically skewed due to an uncorrected instrument calibration issue, forcing the hospital to retest thousands of specimens. We identified experts with experience in clinical laboratory quality control standards, diagnostic testing methodology, and laboratory accreditation compliance. The expert's review of internal quality logs found the issue had been flagged internally but not corrected, supporting the hospital system's claim.
06

Penetration Testing Firm Sued After Undetected Breach

A financial services company sued its cybersecurity penetration testing vendor after a data breach exploited a vulnerability the vendor's most recent assessment had rated as low risk and left unremediated, exposing customer account data. We identified experts with experience in penetration testing methodology, cybersecurity vulnerability risk rating standards, and incident forensics and breach causation. The expert found the assessment had failed to test the exploited system component, supporting the company's negligence claim.
07

Environmental Testing Lab Faces Contamination Report Dispute

A property developer sued an environmental testing laboratory after a site remediation project based on the lab's soil contamination report required substantially more excavation than projected, alleging the original sampling grid was inadequate. We identified experts with experience in environmental site assessment and soil sampling methodology, contamination remediation cost estimation, and environmental laboratory quality standards. The expert found the sampling grid density fell below applicable regulatory guidance, supporting the developer's negligence claim.
08

Testing Vendor Disputes State Exam Validity Challenge

A state licensing board sued its standardized testing vendor after a scoring algorithm error on a professional licensure exam caused hundreds of qualified candidates to be incorrectly failed across two testing cycles. We identified experts with experience in standardized testing psychometrics, licensure exam scoring methodology, and testing vendor contract performance standards. The expert's psychometric review confirmed a scoring key error affecting a specific exam form, supporting the board's claim.
09

A/B Testing Platform Sued Over Skewed Results

An e-commerce retailer sued its marketing analytics platform vendor after discovering that a series of A/B tests used to guide a major website redesign had been run with a flawed randomization algorithm that biased traffic allocation. We identified experts with experience in digital marketing A/B testing methodology, web analytics randomization design, and e-commerce conversion rate analysis. The expert's code audit confirmed the randomization bias, supporting the retailer's claim that the decision relied on invalid data.
10

Usability Firm Sued Over Flawed Study

A software company sued a usability testing firm after a product redesign based on the firm's usability study caused a measurable drop in user task completion rates, alleging the study's test scenarios did not reflect real-world usage. We identified experts with experience in usability testing methodology, human-computer interaction research design, and software product analytics. The expert's review found the scenarios omitted the platform's most common workflow, supporting the software company's claim.
