LIBNOR is a public institution attached to the Ministry of Industry. It was established by a law dated 23/7/1962 as the sole authority to issue, publish and amend Lebanese standards and to give the right to use the Lebanese Conformity Mark (NL Mark).

National standards cover all products falling within the agro-food, chemical, construction, mechanical, electrotechnical and electromechanical sectors.

Moreover, Lebanese standards deal, for example, with measurements, conventions, symbols, methods of analysis and testing, codes of practice for technical work and technical rules and codes for buildings.
