The new 2017 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. Please note: now in 2nd imprint, with minor corrections made to figure 111 on page 162. The following changes were made: =G1=HN1 was changed to =G1=HQ1, and =H1=WP1=XL1 was changed to =H1=WP1=RN1. The corrected page can be seen in the back of the preview file. The Handbook is based on a wide range of updates incorporated into the ISO/IEC 81346 series of standards to be published in 2017. With the new edition of the Handbook, the author Henrik Balslev has emphasised 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 three letter codes to be published in 2017; 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 synchronisation for information across technical boundaries.
