Machine Runoff Testing
Validate Noise Performance
Before Deployment.
Ensure your critical machinery meets performance, safety, and acoustic quality benchmarks, on-site or at the factory, through engineering-grade noise and vibration run-off testing before it’s fully deployed.
Certify Precision Before You Operate.
Original equipment manufacturers (OEMs), system integrators, and end-users all rely on accurate noise data before accepting or shipping a machine. A machine run-off isn’t simply the final startup: it’s your last line of defense against unexpected downtime, compliance failures, and acoustic liabilities. Especially in automated or high-volume environments, unseen noise, vibration, or operational quirks can undermine quality and safety.
At Memtech Acoustics, our Machine Run-Off Testing services, FAT (Factory Acceptance Test), or SAT (Site Acceptance Test), combine precise measurement, performance verification, and acoustic assurance so you can commission with confidence.

- Uncover Hidden Defects Early
Noise or vibration anomalies during run-off often flag misalignments, resonant failures, or mechanical instability that would be costly or risky to catch post-installation. - Prevent Production Disruption
Identifying noise-related faults before full-scale ops avoids delays, rework, and system shutdowns at critical stages. - Validate Acoustic & Safety Performance
Our run-off diagnostics assess noise levels, vibration signatures, safety interlocks, and structural soundness to meet internal and regulatory acceptance criteria. - Provide Audit-Ready Documentation
Certified reports and signatures from FAT/SAT events support compliance, warranty claims, and investment protection.
We test both standalone machines and systems integrated into larger production lines or test cells.
What We Test and Document
Our machine runoff testing services are designed to fit your QA or commissioning process, whether on-site at your plant or in the field. We use calibrated, NIST-traceable equipment and ANSI-compliant protocols.
Sound Power and Sound Pressure Testing
Measurement of machine noise output under normal and full-load conditions.
Octave Band and FFT Analysis
Frequency-spectrum testing to diagnose tonal components or identify dominant noise sources.
A-Weighted and C-Weighted Metrics
Capture of both perceived and peak-level noise performance.
Measurement at Multiple Planes
Evaluate near-field and operator-position sound levels in accordance with ISO 11201 or ISO 3744 standards.
Test Reports and Certificates
Documented test procedures, measurement conditions, compliance evaluations, and pass/fail certifications.
Optional Add-ons
Pre-Runoff Baseline Testing
Identify and mitigate sound issues before formal testing begins.
Runoff Support Consulting
Recommendations to optimize acoustic performance via damping, barrier, or
design changes.

Our Approach & Capabilities
Memtech’s run-off testing services span the full spectrum of industrial and automation equipment.
We conduct Factory Acceptance Tests (FATs) for pre-shipment validation, or Site Acceptance Tests (SATs) post-installation, capturing noise levels, vibration profiles, and safety performance. Our instrumentation includes high-precision sound meters and vibration transducers, synchronized with data logging systems.
We analyze system stability via Cpk/Ppk and MSA, then deliver fully documented results, including run-off checklists, acoustic reports, and compliance certifications. Every test is structured to meet both equipment specifications and real-world operational demands.

Our approach:
- FAT or SAT Execution
Whether at the OEM facility or your site, we replicate real-world operating conditions to test cycles, safety systems, control functions, and acoustic behavior. - High-Fidelity Noise & Vibration Monitoring
Using Class 1 sound meters and accelerometers, we capture tonal spectra, broadband emissions, and structural resonances throughout run-off. - Performance Mapping & Statistical Validation
We assess equipment stability using metrics like Cpk, Ppk, and measurement system analysis (MSA) to confirm repeatability and quality. - Customization & Collaboration
We integrate run-off plans into your project timeline, coordinate with OEM partners, and adapt tests around your operation readiness. - Turnkey Reporting
Detailed reports validate acoustic/vibration performance, safety adherence, and functional milestones with actionable findings and pass/fail documentation.
Who Needs Machine Runoff Testing?
- OEMs preparing for factory acceptance testing (FAT)
- Integrators certifying systems for end-users
- Manufacturers purchasing new equipment with acoustic specs
- Maintenance teams verifying machine upgrades or rebuilds
- Consultants supporting warranty or regulatory compliance

Frequently Asked Questions (FAQs)
What exactly is a machine run-off test?
A run-off is a comprehensive test, FAT at the OEM or SAT onsite, that cycles a machine through operation sequences to validate performance, safety, and acoustic behavior before full deployment.
Why involve acoustic and vibration measurement during run-off?
Noise and vibration testing identifies misalignments, resonances, or structural issues that affect equipment lifespan, operator comfort, and regulatory compliance.
What standards and metrics do you use?
We use Cpk/Ppk for capability, MSA for measurement reliability, and benchmark noise/vibration against applicable industry specs, ensuring results are defensible.
Is this testing mandatory?
While not always required by code, run-off testing offers substantial ROI in reliability, safety, and peace of mind and is critical for mission-critical systems or regulatory oversight.
