NDE ISO 17020 inspection


Non-Destructive Examination (NDE) Inspection Body Accreditation Program

The NDE inspection body accreditation program is designed with the objective to promote confidence in NDE inspection by assuring the quality of inspection bodies and the inspections performed through compliance with ISO/IEC 17020. This accreditation process involves an assessment of the agencies competence for performing many different types of inspections, materials, and environments, along with the consistency of their inspection activities. ANAB accredits agencies that perform inspections of materials, products, installations, processes, or services. Our program is recognized worldwide, as is evidenced by hundreds of ANAB accredited inspection bodies in every corner of the world. If your NDE inspection involves evaluating in place, or manufactured components to ANSI, ASME, AWS, ASTM, Mil Spec, British Standards, or any other industry specification that involves NDE methods, then ANAB accreditation will help you rise to the top. We accredit inspection bodies to all methods of NDE & NDT.

Accredited NDE inspection bodies are required to operate under a quality management system and have processes and procedures in place for assuring the quality of the inspection activities performed. This includes requirements for assuring the competency of inspectors and assuring the validity of inspection methodology and techniques. Along with confirming the technical competence for specific inspections, ANAB will ensure that your organization has the appropriate management system procedures in place, per ISO/IEC 17020, to maintain that competence.

The ANAB inspection program will help move your inspection body towards global recognition, consistent operations, and a competitive advantage that will provide assurance of the quality of inspection activities with the objective of promoting confidence in your company’s inspection program. Accreditation is often regarded as an internationally recognized approval and helps your inspection reports be accepted more readily. ANAB accredited inspection bodies are recognized internationally, helping to reduce costs for your clients.

Our goal through accreditation is to improve the quality of NDE inspection bodies and the quality of the data they produce. ANAB accreditation managers have direct, relevant experience in the NDE Inspection Industry and are backed up by inspection experts that also have practical experience in the field and are often viewed as peers to the inspection bodies. Many of our assessors are NDE professionals, with current or previous ASNT credentials, metallurgy experience, and most have hands on NDE experience.

The ANAB inspection body accreditation program is well-established and should be your choice for accreditation of NDE related inspection activities.
