100 years of DIN

Haus der Normung

On our special celebratory pages you can find out how DIN has developed over the years and what our plans are for the future. We would also like to express our appreciation of all those who participate in standardization and contribute their knowledge for the benefit of German industry and society as a whole.

The most important events in DIN’s history

Experience standards “live” and hands-on.

A wonderful world thanks to standards

Whoever follows the advice of their dentist or pharmacist benefits from it at least twice a day. Here we are talking about the Tuft-retention test: the individual tufts (or what we often call “bristles”) of a toothbrush must be able to withstand a force of 15 newtons according to the International Standard DIN EN ISO 20126. Why? So they stay put in the head of the toothbrush and don’t end up being swallowed. In practice this works quite well. Before the bristles begin to fall out, they have usually become so bent that we have already bought ourselves a new toothbrush

Summer is the time for BBQs and a good time to check your barbeque for safety. DIN EN 1860-1 requires, for example, that a barbeque with a foldable stand must be able to be locked in operating position to prevent tipping or collapse. In order to prevent your hotdog from falling into the coals, the clear distance between the bars of the cooking grid cannot exceed 20 mm. And according to DIN EN 1860-2, barbeque charcoal is not permitted to contain pitch, fossil coals, petroleum, coke or plastic

One of the most important standards in stair construction is DIN 18065. It specifies requirements for stairs in buildings and was updated most recently in March, 2015. This standard specifies terminology, measuring rules, main dimensions and tolerances – ranging from the landing to the tread (or “going”) to the rise-to-tread ratio.  The result: stairs are comfortable – and safe – to climb.

No, cucumbers have not been standardized. And certainly not their straightness (or crookedness!)

Yet from 1988 to 2009 there was in fact an EU regulation that defined commercial classes for cucurbits. And in order to belong to the class “Extra” the cucumber had to be “well-formed and practically straight”. In the meantime however, the vegetable is allowed to grow as it pleases.
