The University Library provides access to standard searches in many different disciplines for all students and employees, including access to fulltext NS, NEK (IEC), ISO and some NORSOK standards.

A standard describes requirements, specifications, guidelines or attributes that should be used consistently to ensure that materials, products, processes and services are safe, secure and accommodated.
