ÖNORM EN ISO 16826

Issue date: 2025 06 01

Non-destructive testing - Ultrasonic testing - Testing for discontinuities perpendicular to the surface (ISO 16826:2025)

This document specifies principles for the tandem technique and the longitudinal-longitudinal-transverse wave (LLT) technique for detection of discontinuities perpendicular to the surface or almost perpendicular to the surface. The general principles for ultrasonic testing of industrial products are described in ISO 16810. The tandem or LLT techniques can be used for the detection of embedded planar discontinuities. This document gives guidelines for the testing of metallic materials with a thickness between 40 mm and 500 mm with parallel or concentric surfaces. The procedures provided in this document can be used for testing of other materials or smaller thickness if special measures are taken according to a written testing procedure. Phased array techniques can also be applied for the tandem technique and the LLT technique, but additional steps or verifications can be needed.

Frequently Asked Questions about ÖNORM EN ISO 16826

What is a "Single-User Licence"?

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.

How can I get involved in the further development of this standard?

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
