ISO 20486:2017 in the NDT Industry: Ensuring Quality and Reliability


In the non-destructive testing (NDT) industry, the adherence to internationally recognized standards is of paramount importance to ensure the quality and reliability of inspection processes. ISO 20486:2017, also known as “Non-destructive testing – Ultrasonic testing – Time-of-flight diffraction technique as a method for detection and sizing of discontinuities,” is a crucial standard that establishes guidelines for the application of the time-of-flight diffraction (TOFD) technique in NDT inspections. This article will explore the significance of ISO 20486:2017 in the NDT industry and shed light on how NDT and PWHT Solutions, a leading company in the field, excels in delivering these services.

Significance of ISO 20486:2017 in the NDT Industry:

ISO 20486:2017 provides a comprehensive framework for the use of the TOFD technique, which is widely employed in ultrasonic testing (UT) for detecting and sizing discontinuities, such as cracks, in welds and other critical components. The standard offers guidelines on equipment requirements, calibration procedures, test parameters, personnel qualification, and reporting, ensuring consistency and accuracy in TOFD inspections.

The implementation of ISO 20486:2017 brings several benefits to the NDT industry, including:

  1. Enhanced Reliability: By following the standard’s guidelines, NDT practitioners can ensure that TOFD inspections are conducted consistently, resulting in reliable and repeatable results. This reliability is essential for critical applications in industries such as aerospace, oil and gas, power generation, and manufacturing.
  2. Improved Detection and Sizing: ISO 20486:2017 specifies the parameters and procedures for TOFD inspections, facilitating the detection and accurate sizing of discontinuities. This capability enables early identification of potential defects, preventing costly failures and ensuring the integrity of inspected components.
  3. Industry-wide Consistency: The adoption of ISO 20486:2017 promotes consistency in TOFD inspections across different organizations and laboratories. This consistency allows for seamless collaboration, reliable comparison of inspection results, and streamlined quality assurance processes.
