Each of our service categories is designed to meet industry codes like ASME, AWS, and SNT-TC-1A. Click to learn more about each testing method and how it applies to your systems or facility:

Clean Room Testing

Ensure ISO-class compliance with certified cleanroom validation. We evaluate particulate counts, pressure differentials, and airflow velocity to certify contamination-free environments.

HEPA Filter Testing & Certification

Verify air cleanliness and leak-free operation of filtration systems. Our HEPA testing team performs DOP aerosol integrity testing for hoods, laminar flow cabinets, and HVAC units.

Leak Testing

Detect microscopic leaks using advanced helium mass spectrometry. We offer vacuum decay, bubble emission, and pressure testing for sealed vessels and barrier systems.

Ultrasonic Testing (UT)

Pinpoint hidden flaws or material thinning with high-frequency ultrasonic waves. UT inspections are ideal for welds, pipes, and structural components.

Magnetic Particle Testing (MT)

Identify surface and shallow subsurface cracks in ferromagnetic materials. Our MT services use wet and dry yoke methods with fluorescent or visible particles.

Liquid Penetrant Testing (PT)

Reveal surface-breaking defects on non-porous materials using dye inspection. Perfect for castings, forgings, and non-magnetic metals.

Visual Inspection (VT)

Perform code-compliant visual assessments of welds, joints, and surfaces. Conducted with the naked eye or magnification tools for surface-level defect detection.

Third-Party NDT Inspection

We provide independent third-party inspections for manufacturers, contractors, and facility owners. Services include witness testing, vendor surveillance, and code compliance verification across every project stage.

Procedure Review – ASNT Level III Consulting

Our ASNT Level III consultants offer procedure development and compliance review for SNT-TC-1A, ASME, and AWS standards. Ensure your NDT methods meet critical inspection codes from the ground up.

Data Center & AI Center Inspection & Testing

Ensure your data center or AI facility operates at peak performance with TN NDT’s ASNT-certified inspection and testing services.
