Understanding the DIN Specification


The DIN Specification, or DIN SPEC as it is usually stylised as, is a certification standard that specifies certain requirements for a variety of industrial machinery components such as Continental Variflex Belts.

While they are a widely trusted certification for a variety of products, it should be noted that DIN SPECs differ from full standards as they do not require a full consensus and involvement of all stakeholders. They are simply drawn-up in temporary workshops by the interested parties and published for review.

How General Standards Are Developed

Standards are created by people who need them have a vested interest in them being used within their industry. They usually involve a transparent development process with the consensus principle in place to ensure a fair and reliable result. Everyone interested in a specific standard can propose one and participate in its construction.

The normal process involves a draft version of an industry standard being published before the standard is officially adopted so that others can see it and contribute to improving it. Experts working on a standard must all agree on its content before the draft is published, and thus again for any proposed amendments.

How to Create a DIN SPEC

Acquiring a DIN SPEC is perhaps the quickest way to turn research into a marketable product. As the economic success of a good idea can depend largely on how long it takes to reach the market, getting a DIN SPEC can be crucial. For a product such as Continental Variflex Z Belts, they must apply for the DIN SPECs that already exists. These were previously created, but it is also possible to create a new one.

DIN SPECs are created in temporary workshops brought together specially to develop and finalise the specification. They can be published within months of their creation being implemented. In the workshop, ideas will be exchanged with other involved parties and the ideal way forward will be ascertained together.

It is important that any new DIN SPECs do not conflict with any existing standards or rules of procedure. With worldwide renown, DIN SPECs have become very effective marketing tools that are widely accepted by clients and customers alike.

What’s more, DIN SPECs can and often are used as a starting point for developing a full standard.

DIN is the German Institute for Standardization

Founded back in 1917, DIN is an independent platform for standardization in Germany as well as the wider world. They operate as a partner for industry and research and play an important role in “supporting the marketability of innovative solutions through standardization”.

DIN benefit from the expertise of nearly 35,000 experts from the fields of industry, research, consumer protection and the public sector. All relevant persons bring their own expertise to work on DIN’s standardization projects.
