scope:

The 2020 edition of DS Handbook 166 (in English) will give you an easily understandable explanation and associated examples of how to use the common ISO/IEC 81346 series of standards dealing with reference designation systems (RDS) for structuring systems and their component parts. The Handbook is fully updated including major updates incorporated into the ISO/IEC 81346 series of standards published in 2019. With the new edition of the Handbook, the author Henrik Balslev has emphasized that ISO/IEC 81346 aims at creating a common language across technical disciplines. The updated Handbook therefore includes a new and more basic understanding of modes of thinking and a description of how ISO/IEC 81346 is used as a common designation method for systems. In addition to the extensive updating, the new edition also includes the new type aspect (%); the new letter codes to published in 2020; completely new codes for spaces; examples of properties, and a new extensive car wash example that shows how RDS can be used as a common point of synchronization for information across technical boundaries.
