Importance of Working with Accredited and Certified Labs
When it comes to non-destructive testing (NDT), the accuracy of inspection results depends heavily on the qualifications of the laboratory and technicians performing the work. Working with an accredited and certified lab helps ensure inspections are performed according to recognized industry standards, using validated procedures, calibrated equipment, and qualified personnel.
At WH Labs, our Houston NDT services are backed by ISO 9001:2015 and ISO/IEC 17025:2017 accreditation and performed by ASNT-certified Level II and III technicians. These qualifications support consistent quality management and reliable testing results across critical industries such as aerospace, petrochemical, and infrastructure.
Why Accreditation Matters in NDT Testing
Accreditation demonstrates that a laboratory follows established quality management systems and standardized testing procedures. WH Labs maintains ISO 9001 and ISO/IEC 17025 accreditation to ensure consistency, documentation control, and reliable inspection processes across all NDT methodologies.
For industries where safety and structural integrity are critical, accredited testing helps verify that inspections are conducted according to recognized standards, including ASTM, ASME, and aerospace requirements.
WH Labs also follows ASTM testing standards and operates within an ASME-certified facility to support compliance with industry regulations and quality assurance requirements.
The Importance of Certified NDT Technicians
NDT results are only as reliable as the personnel performing the inspections. WH Labs employs Level II and III ASNT-certified technicians across multiple inspection disciplines, including:
- Ultrasonic testing
- Radiographic testing
- Magnetic particle testing
- Liquid penetrant testing
These certifications confirm that technicians are trained to perform inspections properly, interpret results, and follow industry-approved procedures.
For example, the WH Labs team maintains Level II and III ASNT certifications to support compliance with ASTM, ASME, and aerospace inspection standards. Our magnetic particle testing procedures are calibrated to ASTM E1444 standards, while liquid penetrant inspections follow established protocols for accurate flaw detection.
Reliable Detection Through Advanced Inspection Capabilities
Accredited labs must maintain inspection equipment and procedures capable of producing accurate and repeatable results.
At WH Labs, our ultrasonic testing capabilities can detect defects as small as 0.5mm in critical aerospace components. Our radiographic systems achieve sensitivity levels capable of identifying defects as small as 1% of specimen thickness.
We’ve invested in advanced technologies such as:
- Digital radiography
- Phased array ultrasonics
- Computed radiography (CR)
- Digital detector arrays (DDA)
- Thermography
- Digital shearography
These technologies help identify internal flaws, delaminations, corrosion, inclusions, and structural discontinuities without damaging the tested components.
Supporting Quality Assurance and Regulatory Compliance
Certified laboratories play an important role in helping organizations meet industry regulations and inspection requirements.
WH Labs follows standards, including:
- ASTM E1316
- ASTM E1742
- ASTM E494
- ASTM E1444
- ASTM E165
- ASME BPVC Section V
- ISO 9712
Our compliance management system tracks regulatory updates to help ensure testing methodologies remain aligned with current industry standards.
We also maintain structured certification and recertification programs aligned with ASNT SNT-TC-1A and NAS-410 guidelines, including continuing education, practical examinations, and documented qualification requirements.
Quality Assurance in Critical Infrastructure
Accredited and certified NDT laboratories help reduce the risk of structural failures by providing dependable inspection data for critical infrastructure and industrial assets.
WH Labs implements a proprietary 7-point inspection process combining:
- Ultrasonic testing
- Radiographic testing
- Magnetic particle testing
This integrated approach supports comprehensive structural integrity assessments for bridges, dams, power facilities, aerospace components, and petrochemical infrastructure.
According to our project data, these methodologies have helped reduce catastrophic failures by 87% while extending infrastructure lifespans by an average of 12.3 years.
The Value of Working with an Accredited NDT Lab
Choosing an accredited and certified NDT laboratory provides confidence that inspections are performed according to recognized standards by qualified personnel using validated procedures.
At WH Labs, our combination of ISO 9001 and ISO/IEC 17025 accreditation, ASNT-certified technicians, advanced inspection technologies, and adherence to ASTM and ASME standards supports accurate defect detection, regulatory compliance, and long-term asset reliability across critical industries.
