Standards work at DIN results in the publication of either a national standard, or a European Standard or International Standard adopted at national level. Their origin is indicated as follows:
DIN (plus number, e.g. DIN 1234)
National standard that has been developed at national level only and is primarily of national interest. Although the numbering system is not officially classified, standards on the same subject sometimes have similar numbers.
DIN EN 1234
European Standard that has been adopted, unchanged, at national level and which has been developed by the one of the European standards organizations, CEN, CENELEC or ETSI.
DIN EN ISO 1234
European Standard that is identical to an International Standard (i.e. it was developed by ISO or IEC and adopted by CEN/CENELEC) and has been adopted, unchanged, at national level.
DIN ISO, DIN IEC or DIN ISO/IEC 1234
This is an International Standard, published by ISO, IEC or ISO and IEC jointly, which has been adopted, unchanged, at national level.
Other standards deliverables:
Some of the results of our work do not have the status of a „German Standard“, because they differ from these in the type and duration of the development process and their binding nature. The documents resulting from the not completely consensus-based technical rule-setting are called Technical Specification (TS), Technical Report (TR) or DIN SPEC.
Technical Specification (TS)
A DIN SPEC developed according to the prestandard procedure is the result of standards work that has not been published as a full DIN Standard due to certain reservations regarding its content, or because the development process has deviated from that for a full DIN Standard, or in consideration of the framework conditions of European standardization. In most cases, it can be expected that such a document will eventually be brought out as a full consensus standard, with any necessary modifications, and the DIN SPEC version will be withdrawn without replacement.
A TS is the result of a standardization work that is not published as a standard by DIN due to certain reservations about the content or due to the setting up procedure that differs from a standard or with regard to the European framework conditions.
A DIN/TS is the result of a DIN working committee. Technical Specifications from CEN/CENELEC are adopted nationally unchanged as DIN CEN/TS. If the working committee decides to adopt a Technical Specification from ISO or IEC that was not adopted by CEN or CENELEC, it is adopted as DIN ISO/TS or DIN IEC/TS.
The principles and rules laid down for standardization work apply to TS, in particular the requirements for uniformity and freedom from contradictions with the German set of standards.
Like a standard, a DIN/TS is drafted according to the rules of DIN 820. DIN/TS offer the public the opportunity to use results from standardization projects that cannot be published as a DIN standard due to a lack of consensus or due to certain reservations about the content. In addition, in contrast to a standard at DIN/TS, the draft publication can be omitted.
The preparation of a DIN/TS is accompanied by the relevant standards committees.
DIN/TS must be reviewed every five years. A decision is made as to whether this will be converted into a standard, whether it should be withdrawn, whether it should be revised or whether it will be retained unchanged. If a DIN/TS is retained unchanged, this decision must be reviewed annually.
Technical Report (TR)
A TR is a status report that contains findings, data, etc. from standardization projects, which provides information on the status of standardization - including other international and regional standardization organizations - and which can be used as a basis for later standardization work.
A TR is the result of a DIN working committee (DIN/TR) or the adoption of a European (e.g. DIN CEN/TR) or international (e.g. DIN ISO/TR) work result.
DIN/TR serve to safeguard data and knowledge that has been obtained once by documenting the work results of the standardization work that should not be published as a standard or DIN/TS.
A DIN/TR is drafted according to the rules of DIN 820. The responsible DIN working committee decides whether to issue a DIN/TR.
