What is a DIN standard?

Official document

Table of Contents

A DIN standard is one of the most recognised standards in the world. Starting in Germany in 1917, DIN has created a wide range of standards that includes around 34,000 standard documents.

Here we go through who DIN are and what are the standards.

What does DIN mean?

DIN refers to the German Institute of Standardization (“Deutsches Institut für Normung”) which are a non-profit organisation founded in 1917 in Berlin, to develop norms and standards for many products including metric fasteners.

Germany has always excelled in the engineering field and the work done by DIN has improved their ability to work in the highly competitive and technical fields. Their importance has helped them gain a solid worldwide reputation, allowing them to join the International Organization for Standardization (ISO).

The primary aim of DIN is to develop consensus-based standards that meet market requirements – all members often take an active role in the decision-making process.

What is a DIN standard?

The “standard” has been defined as a “document, established by consensus and approved by a recognized body that provides, for common and repeated use, rules, guidelines or characteristics for activities or their results, aimed at the achievement of the optimum degree of order in a given context”. They provide detailed specifications for products, procedures, and services.

However as standards become more internationalised there have been some changes to the abbreviations used to publish them:

  • DIN – German standards
  • DIN EN – European standard that has been adopted by the DIN
  • DIN EN ISO – International standards that are also standards approved at a European level
  • DIN ISO – An International standard that is also applied in Germany


Although DIN is still one of the most common standards due to the high respect globally for the DIN, they are still used where there is no International or European standard.
