Understanding NDT Inspection Company Certifications: ASNT Level III, API 510, API 570

Why Certifications Matter

Certifications are not just badges — they represent a supplier's commitment to documented quality systems, regular audits, and continuous improvement. For regulated industries like aerospace, defense, and medical devices, working with a certified NDT inspection company isn't optional — it's a contractual requirement that flows down from OEMs and prime contractors.

ASNT Level III Certification

ASNT Level III is an important quality standard for NDT inspection companies, demonstrating compliance with industry-specific requirements and a commitment to quality processes. When evaluating suppliers, verify that their ASNT Level III certification is current and covers the specific scope of work relevant to your project.

API 510 Certification

API 510 is an important quality standard for NDT inspection companies, demonstrating compliance with industry-specific requirements and a commitment to quality processes. When evaluating suppliers, verify that their API 510 certification is current and covers the specific scope of work relevant to your project.

API 570 Certification

API 570 is an important quality standard for NDT inspection companies, demonstrating compliance with industry-specific requirements and a commitment to quality processes. When evaluating suppliers, verify that their API 570 certification is current and covers the specific scope of work relevant to your project.

ISO 17025 Certification

ISO 17025 is the international standard for testing and calibration laboratories, demonstrating technical competence and the ability to produce precise and accurate test and calibration data. When evaluating suppliers, verify that their ISO 17025 certification is current and covers the specific scope of work relevant to your project.

How to Verify Certifications

Always request a copy of the supplier's certificate and check the scope, expiry date, and certifying body. For AS9100, you can verify through the OASIS database. For ISO certifications, check with the accreditation body listed on the certificate. Our directory pre-verifies supplier certifications, but conducting your own verification is a best practice for critical projects.
