NDT.net was founded by Rolf Diederichs in 1996 and is the oldest existing online platform within the NDT Sector.

As a pioneer on the Internet, Rolf Diederichs took the initiative to develop an online platform for the entire NDT community to freely access and exchange knowledge. The website started as a collection of articles, which were published in a monthly journal and stored in an Open Access Database. In response to researchers’ and professionals’ interest to discuss individual questions, ideas and problems, NDT.net added a discussion forum to the website. From the very beginning, NDT.net was a pioneer, providing networking for NDT proffessionals. Later, this function turned into the MyNDT network. Another early service of NDT.net was the delivery of e-conference proceedings, which were simultaneously published in the database. Further, NDT.net introduced an online exhibition, where companies can display their products and services.

Parallel to constantly developing the online platform, NDT.net developed the Conference Management Cloud (CMC), an online program for conference organizers. This service was complemented by a Conference & Proceedings Web App in 2014. The App is connected to the data of the CMC and serves as a guide for conference participants and a worldwide reference for conference contents.

Today, NDT.net presents an integrated communication platform for the NDT Sector. Thanks to Sponsors and Exhibitors, NDT.net offers free of charge access for the NDT community since 1996.
