Technical standards, quality regulations and delivery conditions

from Wikipedia, the free encyclopedia

The technical standards, quality regulations and delivery conditions (TGL) were binding standards for tangible and intangible objects drawn up by the state in the German Democratic Republic (GDR) from 1955 to 1990 .

The TGL standards were - in contrast to the DIN standard in the Federal Republic of Germany - regulation with the character of a law and were not just a recommendation. They were published in special editions of the Law Gazette , TGL paperbacks and in magazines. The GDR standards and the department standards applied to the entire economy ; the factory standards applied to the respective companies .

A state authority based in Berlin-Köpenick was responsible for the standards. This was founded in 1946 as the German Office for Measures and Weight (DAMG), renamed the German Office for Metrology (DAM) in 1961, in 1964 as the German Office for Metrology and Goods Testing (DAMW) and in 1971 as the Office for Standardization, Metrology and Goods Testing (ASMW) . In 1990 the ASMW was taken over by the German Institute for Standardization (DIN).

The TGL quality regulations defined minimum quality regulations for issuing the GDR quality mark . The TGL regulated a larger range of topics than comparable DIN standards and were at the same time the generally known state of the art in the GDR.

In the mechanical engineering sector, many TGLs were identical with their DIN equivalents or largely agreed in order not to endanger the West exports of the GDR mechanical engineering companies. A clear identification feature for this was the numbering with a leading zero , e.g. B. there was a TGL 0-933 based on DIN 933. For a TGL 0 -... there was (almost) always a DIN ... with the same content.

However, there was also TGL on the same topics as DIN, but these have developed in different directions over time. An example of this is the TGL 18395 compression springs. Wire diameter 0.5 to 16 mm . For this purpose there is the similar DIN 2098-1 cylindrical coil springs made of round wires; Sizes for cold-formed compression springs from 0.5 mm wire diameter . Both standards differ in the designation structure and also in the selection series, so that compression springs according to TGL 18395 are still used today, as these cannot be interchanged with springs according to DIN 2098-1. For dams was considered as the TGL 21,239th you as true today where in the 19700 DIN otherwise provided.

Today the University Library of Weimar and the German National Library (DNB) have extensive collections of TGL and registers of state standards of the GDR. The digitized TGL holdings can be accessed online free of charge via the catalog of the German National Library and the TGL directory of the University Library Weimar. The Weimar TGL collection is being digitized in collaboration with the Federal Institute for Building, Urban and Spatial Research (BBSR). Both projects will be continued.
