DIN/ EN/ ISO differences
Gain an insight into the difference between DIN, EN and ISO standards!
Here you can find information on what changes have been made to the respective product standard and what differences between the DIN, EN and ISO standards this has caused. Get an overview and use the clear direct comparison of the withdrawn DIN standards and the current EN and ISO standards.
In the past, standardisation work in Germany was carried out on a national level by Deutsches Institut für Normung e. V. (DIN). On a European level there are also EN standards, as well as ISO standards on an international level, which are issued by the International Organization for Standardization.
National standards (DIN) are largely being replaced by international and European standards. DIN standards are now only issued for products that have no ISO or EN standards
In accordance with the task and objective of the ISO, which was founded in 1946, international standards (ISO) are intended to standardise technical rules worldwide, thus simplifying the exchange of goods and removing trade barriers.
The purpose of European standards (EN) is to harmonise technical rules and laws within the single European market that was jointly established on 01/01/1993. As far as possible, existing ISO standards must generally be adopted as EN standards in unaltered form. The difference between ISO and EN standards is that, following the decision of the European Council, EN standards must be adopted and implemented immediately and without any changes as national standards in the member states, and, at the same time, the corresponding national standards must be withdrawn.
