Standardization - whether national, European or international - is systematic. This is also true of the identification of standards: Each standard number includes a letter or combination of letters (acronym) indicating the nature of the document and its relationship with other technical rules. This bilingual (German/English) Beuth Pocket will help anyone working with standards quickly find their way around the standard numbering system, making it easier to find the documents they need. Numerous examples and illustrations round out this practical guide. This 6th edition has been completely revised and expanded to reflect the revision of the DIN 820 series of standards as well as the latest developments in standardization.
