Overview of standards – defined standards in the 19” sector

As a company which operates internationally in the field of enclosures, and a major partner to electronics markets, we always do our best to offer our products in a standard which applies worldwide. For the 19” sector in particular, this means that internationally valid standards are required which define dimensions – depending on the model – and the possibility of physical integration. In addition, criteria for electrical compatibility as well as shock and vibration resistance are defined most precisely in individual standards, and this ensures reliability worldwide.
