NoRA: searching for standards

The database contains information on more than 15,500 standards. The special ErgoNoRA search tool locates standards in the area of ergonomics search tool locates standards in the area of ergonomics.

"NoRA" is a German acronym for Normen-Recherche Arbeitsschutz and is a comprehensive search tool for OSH-relevant standards. The cornerstone of the NoRA system is a database which was generated by selecting German, European and international standards concerning OSH from the DITR database and is updated every month by adding and indexing new standards. The standards are classified according to application areas and hazard category and are complemented by a comprehensive list of search terms related to OSH. This means that, besides the usual search fields such as document number, date of publication and title, NoRA users can base their search on other additional categories.

With this system, keywords are simply selected from existing index lists for each search field. By combining keywords from the fields of “Application areas” and “Hazards”, the user can narrow the search down to more specific OSH-related points.

NoRA displays the search results in the form of a list of standards titles. The user can click on the relevant standard to view a summary and thus determine whether the standards selected by the system meet his or her needs Additional detailed information on the standard can be displayed in another box.

Anyone is able to use NoRA free of charge. This ensures that SMEs will also have an easy way of searching for the OSH standards relevant to them.
