Perinorm becomes Nautos


Access to standards is changing; Perinorm will be discontinued at the end of the year. Beuth-Verlag, through which DIN standards and VDI guidelines are licensed by tub. will instead use a new platform: Nautos

To give you time to get to know the new platform, we are offering access to Perinorm in parallel until the end of the year.

What´s new?

The functions remain the same, but the search is structured somewhat differently in Nautos in contrast to Perinorm. In the start search field you can only search for the document no., not for terms. However, the free text search can be found under the link “Advanced search fields”.

Here, in addition to the free text search, extensive search options are offered, such as by ICS classification, document type, country code, date of issue or even a dynamic search with Boolean operators.

A new feature compared to Perinorm is the possibility to search within a document. In an XML view, it is possible to filter by the categories formula, image or table in order to display certain aspects of a standard more quickly.

How do I get my document now?

The download of a standard is triggered by clicking on this button.

Icon for Download

First the standard appears in a preview and then the PDF download is possible via the menu bar above the document, if the license allows this and you are within the TUHH network.

More information

Nautos offers help on the platform in the form of good videos and a FAQ. However, you are welcome to contact us personally if you would like an introduction to standards research.
