Setting state-of the-art Benchmarks
VDI-Standards: Setting state-of the-art Benchmarks
With its VDI Standards, the VDI e.V. supports all those who are faced with technical challenges in their daily work. As one of the most important standardisation authority, it publishes up to 250 VDI Standards per year. These are pioneering and practice-oriented technical regulations that set quality standards in many performing trades and all kinds of industrial sectors. They reflect the current state of the art - competently prepared by experts for experts.
More than 2,100 valid VDI Standards can currently be searched in the VDI Standards database. In addition to detailed information on the standards, the database also contains data on planned and reviewed VDI Standards as well as on withdrawals and notifications of withdrawal.
VDI guidelines provide solutions for processes and problems
Every year the VDI e.V. publishes between 200 and 250 new or revised standards. Most of them are published in German and English. Their aim is to provide technical process and problem solutions that are easy and quick to implement. They are extremely practice-oriented in structure and offer practical checklists and useful tables. The VDI Standards are developed by engineers for engineers. Around 10,000 honorary experts from science, industry and public administration are involved. They set standards in more than 600 committees, which are coordinated in the VDI Technical Societies. This makes the VDI one of the most important standardisation authorities in Germany.
Feedback from experts is welcome
The VDI Standards are the result of an interactive process lasting several years. The advisory boards of the 50 VDI departments determine the topics. The experts work on the draft for a standard for about two to three years. The experts exchange information at regular meetings. Once the draft is approved, it is published. In a public objection procedure, criticism and suggestions for changes from the experts can be submitted.

A VDI Standard is a future-oriented, practical working document. With its assessment and evaluation criteria, it provides well-founded decision-making aids and forms a benchmark for flawless technical procedures. VDI Standards provide experts with the certainty that they are guided by a recognized rule of technology and act accordingly. In principle, VDI Standards have the character of recommendations. Initially, anyone is free to apply them, i.e. they can be used, but do not have to be. The application of a VDI Standard does not release the user from the responsibility for his own actions and is therefore at his own risk. Experience has shown that in a legal dispute, a court will base its decision on the state of the art, i.e. as a rule on the standards and guidelines available for this purpose.
If a VDI Standard is withdrawn, it no longer meets the recognized state of the art at the time of withdrawal. In many cases, not all parts of the text, especially the general content, are necessarily incorrect or outdated. Replacement and/or follow-up documents are referred to on the VDI website.
Withdrawn VDI Standards, which for example form the basis of a private law contract, remain valid for this particular contract. This also applies to contracts concluded after the withdrawal.
Withdrawn VDI Standards are also available from Beuth Verlag. For withdrawn VDI Standards, the citation rules for e.g. bachelor and master theses, dissertations, lecture notes or textbooks continue to apply.
Before a VDI Standard is published, a draft or amended VDI standard is published. Within a time-limited objection period, anyone can submit criticism and suggestions for changes during the objection procedure, for example using an objection form.
Objections must be submitted in formal written form to the responsible VDI Technical Society, preferably by e-mail in the form of the table template provided by the VDI on its Internet pages.
The responsible VDI Standards Committee examines all comments within approximately three months after the objection period has expired. The principles of section 3 of VDI 1000 (VDI Standardization work; principles and procedures) apply here.
A decision on the consideration of objections is made according to the principles explained in section 4.5 of VDI 1000. Each objector will be informed in writing of the result of the examination of his/her objection.
If a VDI stadard is revised, in exceptional cases a draft VDI standard amendment can be published instead of a new VDI standard draft, which contains only the amendments to the VDI standard concerned. This procedure is only permissible if only minor changes are made to the VDI standard. These are, for example, changes of a predominantly editorial nature and adaptations to ordinances, laws or similar.

A network license offers you the following advantages:
- The time-consuming borrowing of VDI standards from the standards body or requesting a licensed copy is no longer necessary. You have access to the desired documents at any time.
- Every employee can research and call up any required VDI standard on your intranet from his or her own PC, for example with the help of your document management system.
- An unlimited number of employees can simultaneously access the same VDI standard. So you only need to order a VDI standard once.
